[Scenario Seed] Repurposing Video Game Plots

[thereviewer]

So as a follow-up to my Repurposing Movie Plots, here's a section where you can reimagine various video games as scenario seeds for your adventures. Here's a few of mine:


Isolated (Based on Alien: Isolated)-



Introduction:
The players agree to assist in helping a company to evacuate the residents of a futuristic-styled space travel corporation (basically airports but with space ships instead of planes). Unfortunately, when they get there, they find the place abandoned and discover why. An old enemy species of theirs (take your pick), has taken over, and the company wants the species brought back so they can study the creatures and make their own version. To make matters worse, the station's androids have malfunctioned and are now targeting everybody seeing everyone as a hostile. The players must evacuate those who came, stop the species, and prevent the company from getting their hands on the creatures.

Things To Do:

 Explore the facility, craft items, study the record logs.


Antagonists:

The Company, whatever species you choose to use in place of the Xenomorphs, the Android Helpers.


Action Scenes:

Fighting back against the species, evading/figting the Android Helpers, crafting items, evacuating the station.


Visuals:

Alien: Isolation, obviously. Or just kick back and watch the first two Alien movies back-to-back.


Problems:

The Android helpers have a neural mind and even if one is somehow reprogramed, there's still over a dozen more to deal with.


Things To Prepare For:

This is very much a survival game. The reason I think Isolation worked so well is because of the fact that unlike the mega-flop that was Colonial Marines, it dared to step (mostly) away from FPS material that the Alien Franchise had become known for. Don't have people running around finding too many guns. Instead, encourage crafting as a means of both improvising, and themes on Survival.


Continuing The Adventure:

 The Company could become a recurring villain. It would not be the first time a Doctor Who story dealt with a dangerous corporate business as Titan Comics The Eleventh Doctor Year One dealt with the Doctor dealing with such a case, but on a much larger scale.


The Pages of Death (Based on Slender: The Eight Pages)-



Introduction:
The players find somebody in the middle of the woods rushing to collect pages. They realize that a creature is hunting him that appears whenever another page is collected. It cannot be killed by any conventional means. It turns out the creature is caught between our reality and another, similar to the Cybermen of Pete's World during the Battle of Canary Wharf
. It is attracted to the pages which are in fact, part of the creature, but have gone out of sync with it. Now the players must find a way to reunite the creature with his pages before it kills them all.




Things To Do:

 Explore the surroundings, collect the pages


Antagonists:


Slenderman (You can even rename him if you wish)


Action Scenes:


Trying to get the pages together, and back into the creature's frequency.


Visuals:


Slender: The Eight Pages.


Problems:


Much like the Weeping Angels, The Creature can pop out at anywhere and at any time. What's worse is that the longer one looks at him, the less time it will take for him to kill you. Also there's the problem of trying to get the pages back to him.


Things To Prepare For:


This is very much a jump-scare story like Blink. However, do try and not overdo the jump-scares. Have them be well-paced and far apart. Also, don't be constantly making jump-noises. Scary scenes can still be made without the need for jump sounds. Look at Halloween 6: The Director's Cut for further proof.


Continuing The Adventure:

New sets of pages start turning up. Someone has the idiotic idea to turn it into a book. Now the players must collect the book copies before the creature kills those who buy the cursed literature.

I'll post more soon!

[thereviewer]

Okay, here's a few more repurposed video game plots:

Aggressive Intelligence (Based on Five Nights at Freddy's)-







Introduction:

The players land at an interplanetary family-styled restaurant with the universe's biggest arcade and the highlight of the diner; the best animatronics found in any point of time and space. Unfortunately, something has gone terribly wrong. The security staff are holed up in a room against the now-sentient animatronics. Some kind of sentient force (it could even be the Great Intelligence if you want,) has taken control of the animatronics and is now using them to kill. Now it falls upon the players to help defeat the rogue animatronics and purge the system of this malevolence.


Things To Do:


Explore the restaurant, discover the force behind the animatronics.
 


Antagonists:


The Animatronics, (whatever villain you decide to use as the puppet master pulling these animatronics' strings.)

Action Scenes:


Evading the animatronics, trying to keep doors shut, boosting the power.


Visuals:


Obviously Five Nights at Freddy's. Basically a happy-go-lucky eatery which has turned into a nightmare.


Problems:


There is very little power in the place so the doors can't keep shut for long. PC's will need to continually boost the power in order to evade the animatronics whilst looking for the source making them so evil.


Things To Prepare For:


Much like 'The Pages of Death' this is a story where the scares come from the tension that pays off with a satisfying Jump Scare rather than one every few minutes. Make sure your scares are sparse enough, or do something different each time, in order to not make it feel like another lame horror movie.


Continuing The Adventure:


Someone sees the potential in this story and tries to make a museum recreation using the designs from the eatery. Unfortunately, his creations are TOO perfect, and now the players must stop the new animatronics from killing everyone in the design department of this facility.

The Enemy on Mercury (Based on Doom [2016])-







Introduction:

The players land on Mercury in the distant future. A colony has taken up residence there and is in the middle of performing a deadly experiment. They have found a way to open a portal to the world where the Dæmons to our reality again. Despite their new weaponry for battle against the Dæmon race, they're quite different from the last time The Doctor encountered them. Due to the events of the Last Great Time War, the Dæmons have received new and improved abilities that make all the new hardware outdated. Fortunately, one of the explorers managed to retrieve a hidden vault from the Dæmon's Home World; a coffin which is said to hold the greatest warrior of the Time War. No, it's not The Doctor. Abslom Daak!

Things To Do:


Explore the colony, get to know Daak (who is revealed to have put himself in a Pandorica-like machine in order to keep himself alive after getting shot during the Time War), making friends with the colonists/scientists.


Antagonists:


The Dæmons. It should be noted that due to the events of the Last Great Time War, the Dæmons have received new abilities similar to the Voord's transformation as seen in Titan Comic's DW Event Miniseries Four Doctors. This is your chance to get creative and come up with a redesigned look/new abilities for the Dæmons, since the effects of the Time War had repercussions on the biology. Absolm Daak might even become an antagonist if the players manage to get him really mad.


Action Scenes:


Defending the colonists against the Dæmons, using the base to its fullest advantage to throw the Dæmons off their game.


Visuals:


Think Doom (2016) if it had been co-designed Steven Moffatt & Co on top of everything else that we got in the finished product. The Dæmons redesign is also a chance for you to stretch your creative muscles.


Problems:


None of the original weaknesses seem to be working on the Dæmons. The players will have to come up with another way to defeat them. Also, Daak is a fuse just ready to go off. However, if you're able to convince him (which might be a difficult thing to do), he'll happily kill anything.


Things To Prepare For:


This is a base-under-siege story. Think Army of Darkness with a sci-fi twist. The players arrive, get trapped with a madman who still has some good in him (even if he doesn't admit it), and have to defend the colony.


Continuing The Adventure:


Daak's wife is out there somewhere, still cryogenically frozen as well. Do the players take him to her? This could make for a wild campaign of a season through time and space in order to find her and reunite them? What happens if they refuse? (Hint: nothing good, most likely!)

Ghouls ate My Planet (Based on Zombies Ate My Neighbors and Ghoul Patrol)-







Introduction:

The players arrive on a planet that they have previously rescued only to find it completely deserted. They discover that resident mad scientist, Dr. Liver, held a grudge against the heroes for saving the planet. He had a really bad flu that day, and claims that had it not been for said flu, he could have single-handedly saved everyone himself. Thus, he decided he would create his own 'invasion' and save everyone himself. He created robotic duplicates of vampires, werewolves, huge demonic babies, squidmen, evil dolls, aliens, UFOs, giant ants, blobs, giant worms, Silurians, Autons, Cybermen, Daleks, Ood, and even zombies. Once he had enough of each robot, he thought that he'd have everything he needed to pull of his 'invasion.' Unfortunately he was wrong and when he brought his creations to life, they became sentient and began running amuck all over this world, outsmarting even Dr. Liver. Now it falls upon the players to team up with planet locals Zelda McDermott and Jack Ebert to defeat the mechanical army and save the day.



Things To Do:


Run around saving the various inhabitants including barbecue chefs, teachers, babies, tourists, inspectors, soldiers, dogs and cheerleaders. The PC's will have to travel with their new friends to many areas on the planet including suburban neighborhoods, shopping malls, pyramids, haunted castles, and lastly Dr. Liver's own massive underground laboratory.


Antagonists:


Dr. Liver's own robotic duplicate army. They come in all shapes and sizes. Vampires, werewolves, huge demonic babies, squidmen, evil dolls, aliens, UFOs, giant ants, blobs, giant worms, Silurians, Autons, Cybermen, Daleks, Ood, and even zombies. Unfortunately, even the old enemies your player might've encountered in the past don't have the same weaknesses as before. Fortunately, they are vulnerable to water which'll short-circuit them, but only for a limited time. Dr. Liver is the endboss as he manages to mutate himself into a giant floating head complete with laser vision, and multiple eyeballs that he can push out which then explode after a few seconds.


Action Scenes:


Fighting against the various creatures, saving the rest of the people here.


Visuals:


This is every Halloween-lover's personal best dream. It's a send-up to Golden Age of Horror Films to the Bronze Age, with your regular Doctor Who mix thrown in for good measure. You can even have robotic duplicates of some of your own original aliens thrown into the mix if you want. Whatever the case, as with Zombies ate my Neighbors, it's a straight-up B-Movie that doesn't try to take itself too seriously, but doesn't talk down to your intelligence either. It's just seeing how many insane things can you handle in a 1980's suburban town-styled setting.


Problems:


As mentioned, the robotic duplicates of any creature your PC's previously faced don't exactly have the same weakness. Also, unless they have a means of traversing Time and Space (I.E. a TARDIS or a Vortex Manipulator,) the PC's better find a good hiding spot for anybody


Things To Prepare For:


I'd recommend viewing walkthroughs of Zombies ate my Neighbors and Ghoul Patrol in preparation. Another good source of inspiration would be to check out the film Monster Squad which has a similar plot of young individuals having to stop an invasion of monsters.


Continuing The Adventure:


After saving the planet, an investigation is put into action into anything else Dr. Liver might've been working on. Somebody finds a chemical formula and accidently gets drenched in the stuff which transforms him into a hideous monster. It's up to the players to stop him and get him back to normal.

Leave your thoughts and opinions here as well as any repurposed game ideas you might have!

I'm back again! Here's a couple more Video Game Plots repurposed for your campaign adventures:

Beyond the Silver Screen (Based on Lakeview Cabin)-







Introduction: The players arrive on a futuristic planet where they discover an abandoned movie theater featuring a film that none of the PC's have heard of before. If there are any Time Agents or Time Lords, even they don't have any info and any attempts to find more info on these films result in nothing. However, something is suddenly apparent. The 'Movie Screen' is actually a portal to the world inside the film. The 'Movie' is actually an artificial pocket reality molded by people with a lot of money. Unfortunately, all the people who went to see it got stuck within the film and are now trapped within the events where they repeatedly fall victim to the hands of the killer 'Childface.' Now the PC's must rescue the inhabitants without becoming victims themselves.


Things To Do:


Explore the theater, enter the movie, convince the people they were not meant to be who they are now, escape the movie.


Antagonists:


'Childface.' Basically your typical Jason Vorheese or Michael Myers-seque-styled killer. Silent, strong, and unnaturally fast.


Action Scenes:


Preparing traps for 'Childface,' Confronting the monster head-on, finding a way out of the film


Visuals:


Basically, this is your typical Friday the 13th/Halloween/Nightmare on Elm Street slasher film, but with your typical Doctor Who twist. The look of the theater is inspired by the Halloween Horror Nights event from back in 2009 with the titular 'Silver Screams' house. More info can be found here: halloweenhorrornights.wikia.com/wiki/Silver_Screams and here: www.hhnyearbook.com/tag/hhn19/page/3/ .


Problems:


Finding out how to pass through the pocket dimension and our reality, how do you stop a killer who has been designed to be in-killable?


Things To Prepare For:

Get ready for paranoia. This is the Weeping Angels times 1000. No matter how hard your players try, they just can't seem to kill this creature as he keeps getting back up even when its assumed that he's dead! This should encourage improvising ways of dealing with a creature. Maybe some old horror movies might help? "What about that film with the guy when the thing comes out of his chest? Didn't they send that alien out into the vacuum of space?"


Continuing The Adventure:


What about the other pocket universe 'movies' in the cinema?! How do other patrons deal with being caught in films ranging from a small suburban neighborhood finds itself terrorized by an un-killable evil on Halloween Night, as opposed to those who find themselves on a space station collecting remains of the original cabin from the first film only to be besieged by mutating monsters, and strange hearings of a lady singing? Either way, you might want to get those people out as well!

In the name of Love (Based on Yandere Simulator)-







Introduction:

The players arrive at a modern school and discover that there is a number of murders going around of everyday high school girls with no connection, rhyme, or reason. After investigation, they discover that the cause is an everyday normal girl who is killing off the girls because she wants the "popular boy" all to herself. There's no alien interference, no psychic control, no alien in disguise, etc. She's a normal girl doing this because of paranoia that if she doesn't "take out the competition," then she'll never have her boy all to herself.


Things To Do:


Explore the school, discover the dark secret, infiltrate the educational building, try to talk reason with this girl.


Antagonists:


The "unpopular girl." (A/N: You can call her whatever you want.)


Action Scenes:


If the players demand for her to stop, then she will become angry and try to kill them as well.


Visuals:


A very-modern-day story. Much like the War Machines, The Web of Fear, and The Bells of Saint John, this is set in the present, and deals with a lot of real-world issues.


Problems:


This girl will not back down from her goal no matter what. PC's will have to roll really high to convince, or take her to a place in time and space to teach her a lesson. Also, as it might be pointed out, even though she's gotten away with her act for so long, she will eventually be found out by the police.


Things To Prepare For:


This is actually partly inspired by some real-world events that I won't get into, but is something we've heard about happening every so often. It is often portrayed mostly in fiction, but this one deals with the rare cases when one's love can go too far. An important note is that much like my Carrie-based adventure, this girl is not entirely evil despite her actions. She's friendly when the players meet her (as she doesn't have any friends,) and is often bullied. To her, this is her getting "what she deserves." This is similar to the DW Novel; 'In the Blood,' where an alien virus is spread through the internet, making people who get angry even angrier until they have a heart attack and die. While they do bring up internet trolls as the first victims, a neighbor of the "troll victims" points out that while he was obese and living with his Mom, he still loved his Mother and loosing her son has devastated her. But meanwhile, everybody else online is making fun of the "fat-slob" who died. In short, it's what Vengeance on Varos tried to be; a story that questions what we do as a species and what we say about other people. Again, it's a thing that should be discussed amongst your players to make sure they're cool delving into a story like this. But in the end, this is meant to be a story about accepting how you can't force things to be your way, but you can also try to be a better person for it.


Continuing The Adventure:


Assuming she survives, the young girl calls back on the PC's when she's arrested for a crime she didn't commit during the time of her murders. The players must find a way to clear her name before she's given a terrible sentence for the accusation.



The Fish-Faced-Family-Man (Based on Octodad)-







Introduction:
The players land in a surburban everyday home where they discover that the man of the house is actually a fish-alien who escaped decimation of his people. Now he's trying to live a normal life, but an incoming bounty hunter might sweep those thoughts away.


Things To Do:


Explore the house, learn the history of the fish-alien, try to cover for him when his wife's around.


Antagonists:


Helece the Bounty Hunter (an original alien I created for this game. Basically think Colony Sarff if he were made up of leeches.)


Action Scenes:


Trying to keep the fish-alien and his wife alive, dealing with Helece.


Visuals:


This is very much a comedic story. Set in a suburban town where the most bizarre things happen. It's almost like an episode of Cartoonnetwork's Courage the Cowardly Dog if anyone remembers that show.


Problems:


Dealing with Helece, the wife is also very ignorant of her husband's unusual behavior of walking funny, grabbing things in an odd way, or why his new friends are insistent on keeping her safe.


Things To Prepare For:


This could be a very difficult story to play, but only because of how crazy the plot can be. Make sure to add touching moments with the Fish-Alien. Remember; he's trying to start a new life and he doesn't want the wife to get heartbroken over loosing him or finding out the truth.


Continuing The Adventure:

A few years later, the fish-alien and his wife have a couple of children. Unfortunately, a genetics facility wants them for study and experimentation and now its up to the PC's to help get those kids back.

and finally, based on my favorite web reviewer;

Game On (Based on The Angry Video Game Nerd Adventures)-







Introduction:
The Celestial Toymaker is back! This time, he's created an all-new video game trap that actually absorbs anyone willing to play it. The PC's find themselves trapped in a bizarre pixilated world and their only way out is to beat the game with assistance from a famous online game reviewer.

Things To Do:

Explore the game world consisting of eight worlds (they can be either inspired by classic video games, ones of your own creation, or the examples I've listed here as stand-ins for what was in the actual game Mansionvania, Sparkling Good Land, Future Freakout 2020, Icy Mountain Zone, Thy Soul Consumed, Dungeons and Pitfalls, Creepy House, and finally Laughing Joking Nation), teaming up with the internet reviewer, getting to the Celestial Toymaker's lair.


Antagonists:


The Celestial Toymaker and his pixilated minions


Action Scenes:


Surfing mode, platforming, shooting, riding giant lava sharks, avoiding obstacles and enemies, defeating the Celestial Toymaker.


Visuals:


This is very much a classic video game story brought to life. Be as creative and old-school inspired as possible, and use as much influence from classic games as you can.


Problems:


Getting past the stages, dealing with the game reviewer's cynicism, defeating the Celestial Toymaker.


Things To Prepare For:


The Angry Video Game Nerd continues to be one of my inspirations (it was because of him that I chose my username as 'thereviewer,' This is a send-up to games of his era and his character in general. You can use the Nerd if you like, although it might be a more adult-oriented game then unless you want to take the route they did when he teamed up with Captain S as seen here: . If you're not comfortable using him, you can have the PC's team up with other internet reviewers (they don't have to necessarily be video game reviewers,) or just make one up as either an original character or an allegory. Then of course there's the Toymaker. Defeating him (as with his other bosses,) should be done using classic video game boss stratagems. For more inspiration and info about the AVGN game itself, check out the AVGN Wikia Page for more inspiration: avgn.wikia.com/wiki/The_Angry_Video_Game_Nerd_Adventures . The AVGN/Captain S crossover that I mentioned is also a good inspiration for how two very different characters can come together for a common cause.


Continuing The Adventure:

After defeating the Toymaker, the games are recalled by U.N.I.T. and buried. However, some REALLY obsessive collectors managed to pull the game out and decided to play it. Now they PC's must once again put their classic game skills to the test and save the day.

Let me know what you think!

[thereviewer]

So I realized that a majority of scenario seeds here are mostly horror-based games. Here are a few more non-horror video game-based ideas:

Return to the Asylum (Based on Batman: Arkham Asylum): 



Introduction:

The PC's are contacted by the Daleks who have recently built another asylum. It turns out the Daleks chose to keep both their asylum a secret from even Davros. They feared Davros would pervert the asylum for his own ends that would affect even the Daleks. However, the mad genius has learned of the secret and plans to release the Dalek nanocloud to spread through the universe like a virus. The PC's must brave the Dalek Asylum and escape with their lives intact.


Things To Do:



 A great way to re-introduce the Asylum. Stopping Davros no matter the cost. A surprising team-up with the Daleks (albeit temporary.)




Antagonists:



The Insane Daleks, Davros, and the normal Daleks (once the threat has been eliminated).




Action Scenes:


Fighting your way towards where Davros has holed up in, defeating any other mad Dalek creations Davros might've unleashed (and possibly upgraded!)




Visuals:



Asylum of the Daleks/and Batman: Arkham Asylum (obviously). If you want inspiration for how the surface of the Asylum could've changed over time, I'd recommend searching for videos on the game Star Wars: Uprising which was (I believe,) the earliest new canon story to be available to the public after Disney announced they'd purchased Lucasfilms with the plans for their sequel trilogy. The game itself takes place between Episodes VI and VII and shows the early years of the Galactic Empire scrambling to fill the hole left by the death of both Palpatine and Vader. In one level, you go to Hoth and get to check out the remains of the Battle of Hoth seen in Episode V. This should be the perfect visual influence to use to have players return post-Asylum of the Daleks. 


Problems:



The Dalek nanocloud. Also, while Davros's main goal is to unleash the cloud into space and have it spread, he knows that people will oppose him so he's repaired some of the Dalek inmates with new and improved upgrades. Then there's the problem of what happens when you've succeeded? Chances are the Daleks won't bother to care for you


Things To Prepare For:



This is basically Asylum of the Daleks done right. You are free here to use as many Dalek designs as you wish spanning from all eras. Hell, you could make your own new designs if you wish, considering Davros is upgrading! Make sure though to remember the stealth and puzzle-solving aspects in areas. One of the reasons Batman: Arkham Asylum did so well is because it used two key elements to Batman that weren't explored much until then; his ability to keep hidden and his ability to be the world's greatest detective. These should be aspects in the adventure as well to give some variety 




Continuing The Adventure:



 The PC's get word that a prison planet has just been unveiled. It turns out that prisoners are allowed to run free in the planet albeit in certain area limits. But they soon discover the mastermind is the Great Intelligence. He's adapted the Dalek Asylum plans and is preparing to control all the inmates when the time is right.


Planet of the Dinosaurs (Based on Jurassic Park: The Game): 





Introduction:

The PC's find themselves on Siluria after the events of Dinosaurs on a Spaceship. The place has become a preservation for the Dinosaurs but someone is trying to smuggle them off-planet and has inadvertently knocked out the security systems for keeping the Dinos in-check and safe from each other (and the general population.) Now the players must try to get off-planet with a few survivors and maybe the Dinosaurs as well before a nuclear missile destroys them all. 


Things To Do:



Discover the planet of Siluria. Try and rescue the Dinosaurs. Learn more about what happened with the creation of the preservation that happened between the end of Dinosaurs on a Spaceship and the time your players arrive. 




Antagonists:



Any carnivorous dinosaurs, dinosaur smugglers.




Action Scenes:



Fighting back against the smugglers, outsmarting (and outrunning) the dinosaurs, getting off the planet before the nuclear missile hits and destroys everyone. 


Visuals:



Definitely Jurassic Park (both the first movie and the game by TellTale which I feel was greatly underrated even if it might not be cannon anymore following Jurassic World.) Another big influence is from Universal Studios Orlando's Halloween Horror Nights event. In 2002, the event moved from Universal Studios Florida to their then-newly-opened sister park; Islands of Adventure, where the then-five lands became five scarezones with haunted houses. The Jurassic Park scare zone was greatly influenced by the scenes in the film where the power goes out and had some stunning visuals. You can read more about it on the Halloween Horror Nights Wikia, and there are a few videos on YouTube you can watch. There's also a forums (I forget the specific name), but it has info about two unused icons along with the detailed description for the original 2002 event. Try searching HHN Cindy and Eddie forums. You'll find it eventually.


Problems: 

Upon hearing that the dinosaurs have broken out, its been decided to quarantine the planet and nuke it from orbit. This creates another ticking bomb. Can your players prevent the bomb from reaching them? Or will they be forced to save as many dinosaurs as they can?

Things To Prepare For:



If Jurassic Park ever got an RPG, this is what it would be like. Get ready to put your survival skills to the test.


Continuing The Adventure:


One of the smugglers was shipping the dinos off to make money for her daughter as they are very poor. She returns home to find her daughter's been kidnapped. Apparently the buyers weren't happy to learn about what happened on Siluria. Now she turns to the PC's for help in getting her daughter back.

Ocean of Trouble (Based JAWS: Unleashed) (Note: With Some Creative Liberties)-




Introduction:

The players arrive on a leisure planet in the future. Unfortunately they soon discover that someone has been messing around with splicing the DNA of Sky Fish from the planet Ember (the planet featured in the 2010 Christmas Special: A Christmas Carol,) with that of normal sharks. Now a freak-accident has resulted in the creation of a Great White which can survive outside of water and fly for limited periods of time. While not being able to fly for as long as the Sky Sharks on Ember, the Great White has nonetheless become a threat to the planet and it now falls upon the heroes to stop it.


Things To Do:



Defeat the flying Great White, interact with other people visiting.




Antagonists:



The Flying Great White. Also, a number of bounty hunters have been brought in to deal with the shark as well. They might become a problem if the PC's get in the way.




Action Scenes:

Fighting the flying Great White, dealing with the bounty hunters (if they get in the way.)


Visuals:


Jaws. Plain and simple. 




Problems:



What do the players do with the scientist responsible? Do they have him arrested? Some of the victims of the Flying Great White are demanding that someone pay for this and your PC's might have different opinions.


Things To Prepare For:



This is very much Jaws. In order to make this work, you should have long moments where the shark is rarely seen, but when it is, make sure it's surprising and just as dangerous. 




Continuing The Adventure:



The PC's learn that the scientist who created the flying Great White had a student. On a floating city in a distant world, a new stage show is about to open involving flying aquatic creatures of all types that don't need to breath oxygen. The PC's will have to go and sort this mess out once more.

The Resonance Cascade (Half-life)
Introduction
The year is 200X (Whenever you want to) and at the top secret research facility of Black Mesa an experiment is about to go wrong. Black Mesa was set up as an independent (but in close quarters with the US government)to examine and study or even reverse engineer alien technology that has been discovered upon US soil. The facility is located deep within the New Mexico deserts save away from public eyes. Gordon Freeman is one of these employees working there and right now is on an important job, testing alien crystals inside of the Anti-Mass Spectrometer which is a room sized device used to examine these crystals. Unfortunately on this very day, various safety precautions were not maintained and checked beforehand but the analysing went along anyways. However, when inserting an unfamiliar crystal into the machine, it begins to expand and soon explode into a flush of Archron energy, causing the facility to shake. And there within the room itself, is a Time Rift, only a small crack but it is leaking things throughout Black Mesa resulting in various experiments failing due to interference and the loss of many lives.
Things the Players need to do
Work alongside Gordon Freeman (who is strangely a person who does not talk at all) in order to escape the base, potentially try and find away to close the Time Rift, manage the things that have been leaking through the rift.
Antagonists
Anything can come through the rift so it is up the GM here what might be inside of Black Mesa.
However there is the HECU or Hazardous Envrionment Combat Unit, a US marine crops special force unit specialised in indoor combat situation involving hazardous environments and unconventional enemies, that is including ETs. They have been tasked to shoot anything on sight, including the scientists and guards already in there,
Action Scenes
Avoiding and dealing with the things that come through the rift, avoiding the HECU from killing the players or even trying to convince them not to shoot you, dealing with damaged parts of Black Mesa. 
Visuals
The game Half Life of course as the source of the inspiration, but various other base under siege episodes of who might work as well for inspiration (the adventure game The Shadows of the Vashta Nerada is one of my recommendations
Problems
Well anything that comes through the rift. A specialised team of the HECU has been tasked to try and locate the automated nuclear defence mechanisms to destroy the base entirely, a deviation may be necessary to track this team down and stop them or even work with them to destroy the facility (in game canon the nuclear warheads do get detonated and does destroy the facility)
Continuing this Adventure
The Time Rift never did close after Black Mesa was (current condition after playthrough) and instead only expanded, and within its other side a hostile interdimensional alien species is watching over the portal ready for the right time to strike at planet Earth, and of course they do. The are only known as The Combine and guess what, they have just won over humanity in a 7 hour war. (See the events of Half Life 2 to know what happens afterwards)

Race Against Space (FTL: Faster Than Light)
Introduction
The year is 3924, The Galactic Federation are still at war with Galaxy 5. The war is putting a devastating effect upon both sides but both push on for victory. However though Galaxy 5 have a superweapon up their sleeve, a powerful a spacecraft they refer to as The Mothership, one that can devastate the fleets of the Federation. Soon the entire fleets of Galaxy 5 have assembled together into one large one fleet around the The Mothership and soon begin to pushforward into Federation Space. As the Federation fleets try to evacuate to a safer distance in preparation for the larger battle, a lone but important ship tries its best to jump from system to system in order to survive. This ship contains crew from various Federation worlds and now your players land within their ship. The players need to work with this crew to get to the Federation fleet in order to make it to safety. However, the history books record this ship as being the one to destroy the Mothership and now that the players are onboard, they must do their best to ensure the history goes correctly.
Things the Players need to do
Jump from system to system in order to escape the approaching Galaxy 5 fleet, do various tasks onboard and maintain the ship at various stations, defend the ship from boarding enemies and as well aid in the weapon systems when other ships are attacking from space.
Antagonists
(Ships and Crew) Space Pirates, Militia, Criminals. Automated Defence Ships, Galaxy 5 etc
Action Scenes
Ship-on-ship combat and the destruction of spacecraft, dealing with boarding crews from Trans-Mat rooms on their ships, dealing with fires or hull damages or broken systems etc on-board the spacecraft
Visuals
The game FTL: Faster Than Light of course however space combat that puts an emphasis on solely on ship-to-ship combat in various other sci fi media might be good inspiration 
Problems
Nebulas, sensors failing, crew death, oxygen damaged and running low, fires, Galaxy 5 on the players tail and should they fall under their fleets range potential chaos etc. 
Continuing this Adventure
The Mothership has been destroyed and a major space battle has concluded with a Federation Victory, however we know by 3925 Galaxy 5 is still around this time on Peladon trying to get access to Trisilicate, perhaps the Trisilicate was to be used in repairing the or constructing a new Mothership, and well even if the war ended in 3925 perhaps rogue elements in 3999 are attempting it again to conquer the Galactic Federation once and for all

Haunted Horrors (Phasmophobia)
Introduction
This one is quite simple, the players arrive in 201X and work with a team of paranormal investigators to investigate the reported ghost sightings at a haunted location (a real world location or a fictional location up to you there)
Things the Players need to do
Investigate the Ghosts: using stuff such as EMF detectors, Spirit Boxes, UV lights for hand prints, motion sensors, cameras etc in order to find the "ghosts", potentially even needing to "exorcise" (or bust) the "ghosts"
Antagonists
The Ghosts, whatever they are they most certainly are the antagonists, the actual origin of the "ghosts" and what they are is up to the GM.
Action Scenes
The "ghosts" scaring the players, things moving "on their own" or being chucked at players, ghostly activity all around, being chased by a "ghost"
Visuals
Phasmophobia the game but also those ghost investigating shows on TV like Ghost Adventures or Most Haunted 
Problems
The ghosts are hostile, and they will seal the place down and will go on a hunt to kill one of the NPCs (or players) lest they hide well and not be captured/killed by the ghosts
Continuing this Adventure
The "ghosts" can feature in other haunted locations as well making them a reoccurring alien/monster here and there as a threat to deal with. Plus the Paranormal Investigators may make a return and enlist the help of the players to go to a new haunted location to investigate new ghosts!

The Resonance Cascade (Half-life)
Introduction
The year is 200X (Whenever you want to) and at the top secret research facility of Black Mesa an experiment is about to go wrong. Black Mesa was set up as an independent (but in close quarters with the US government)to examine and study or even reverse engineer alien technology that has been discovered upon US soil. The facility is located deep within the New Mexico deserts save away from public eyes. Gordon Freeman is one of these employees working there and right now is on an important job, testing alien crystals inside of the Anti-Mass Spectrometer which is a room sized device used to examine these crystals. Unfortunately on this very day, various safety precautions were not maintained and checked beforehand but the analysing went along anyways. However, when inserting an unfamiliar crystal into the machine, it begins to expand and soon explode into a flush of Archron energy, causing the facility to shake. And there within the room itself, is a Time Rift, only a small crack but it is leaking things throughout Black Mesa resulting in various experiments failing due to interference and the loss of many lives.
Things the Players need to do
Work alongside Gordon Freeman (who is strangely a person who does not talk at all) in order to escape the base, potentially try and find away to close the Time Rift, manage the things that have been leaking through the rift.
Antagonists
Anything can come through the rift so it is up the GM here what might be inside of Black Mesa.
However there is the HECU or Hazardous Envrionment Combat Unit, a US marine crops special force unit specialised in indoor combat situation involving hazardous environments and unconventional enemies, that is including ETs. They have been tasked to shoot anything on sight, including the scientists and guards already in there,
Action Scenes
Avoiding and dealing with the things that come through the rift, avoiding the HECU from killing the players or even trying to convince them not to shoot you, dealing with damaged parts of Black Mesa. 
Visuals
The game Half Life of course as the source of the inspiration, but various other base under siege episodes of who might work as well for inspiration (the adventure game The Shadows of the Vashta Nerada is one of my recommendations
Problems
Well anything that comes through the rift. A specialised team of the HECU has been tasked to try and locate the automated nuclear defence mechanisms to destroy the base entirely, a deviation may be necessary to track this team down and stop them or even work with them to destroy the facility (in game canon the nuclear warheads do get detonated and does destroy the facility)
Continuing this Adventure
The Time Rift never did close after Black Mesa was (current condition after playthrough) and instead only expanded, and within its other side a hostile interdimensional alien species is watching over the portal ready for the right time to strike at planet Earth, and of course they do. The are only known as The Combine and guess what, they have just won over humanity in a 7 hour war. (See the events of Half Life 2 to know what happens afterwards)
 

I will say on this idea here is one of those where it can work with a plots within plot style campaigns with a session in different departments of the overall facility being one session. Perhaps technology to close the Time Rift is located within each department and need to go in there to get it, yet a different threat each time within each department to deal with and even the HECU as well. Different NPCs as well may offer insight on their research and where tech is located but also rescuing them can aid and benefit later on. The departments are connected via tram-lines as well so might be a good ending point and get onto the tram to the next department.
