This is the story of a core named "Wheatley". That's it. That's all there is. Would you like to know more? [YES] [NO]

Sequel to Of Ratts and Men. City 17 may have been destroyed, but the Combine still reign supreme over Earth. Now, the Half-Life gang must find the Borealis so they can use portal technology aboard to find Alyx and finally beat the Combine. Lucky for them, three of the best candidates for the task have just rejoined the surface. Not so luckily, the Combine has found them first.

Something in life guides everyone. Sometimes it's people, sometimes it's the choices that are made. Chell is on the surface and finds the world is a much different place than the depths of Aperture. Gordon and Alyx are trying to fulfill Eli's dying last wish but that's easier said than done. While at White Forest Barney Calhoun just tries to keep everything from falling apart.

Come explore this (Slightly depressing) new world where toons were also drawn to test. Explore the testing facility in Dot's life when things take an unexpected and sad turn. (Norita (reboot CEO) isn't in the character select, so I didn't put her.)

A former test subject, now free, takes up residence in a strange town where almost nothing is considered abnormal. A year later, a young paranormal enthusiast spots two odd new satellites orbiting the moon and immediately makes plans to bring them to Earth, firmly believing that the two metal spheres are alien in origin. Because, after all, what else could they possibly be?

A morally grey laboratory with some interesting employees. The 10th Doctor is certain to investigate. Alternate Universe/Out Of Character Portal/2 cast.

Claptrap had only planned on hanging out with this Wheatley guy long enough to drop him off with somebody who could get him back home, but an emergency stop in a place with only one charging outlet put a major snag into THAT plan… [There Was Only One Bed but with robots]

The human race is a lost cause as far as GLaDOS is concerned, but there just might be one person worth her time.

Cooperative testing is supposed to bring people together through science. Cake is often a good motivator, but escaping a madhouse that tries to pass itself off as a science facility works better. Will they escape? Or will the facility keep them clutched in its iron grasp forever?...

Equestria becomes the next Test Subject within the Aperture Science Facility, run by the Central Core: GLaDOS. Unaware where it came from, everyone is rendered around Earth Pony level, & the Mane Six group must overcome the Test Chambers to reach the goal & save everyone else captured. To escape the Test Facility, they'll need help from a new mute friend without a past: Chell.

The last thing I remember is being trapped in the locker; now I'm in some kind of filthy, abandoned research facility, one that's clearly never heard of OSHA or the Geneva Convention. How did I get down here? Am I alone? Most importantly… how do I get out? Maybe I should make something… Tinker!Taylor, sane!GLaDOS

A team of Combine soldiers find themselves in Aperture Labs

Every robot manufactured in Claptrap's universe gets an assigned permanent companionship unit and, despite all signs to the contrary, he has one too. Unfortunately, not only is she a piece of work he doesn't want to spend two minutes with, much less forever, she lives in an entirely different universe. One that doesn't HAVE soulmates... (Soulmate AU)

When the Doctor and Donna land in the Enrichment Center of Aperture Science after 30 years of silence, they decide to explore. Little do they know that they are about to be tested to the max by a lonely, bored AI that had been dormant for 30 years prior. (Crossposted between here and AO3!)

A collection of Half-Life and Portal drabbles, some for the r/fanfiction Discord Drabble Night, some for other challenges and prompts. (The genres only really describe the first one, since there's a lot of variety, although I guess they're all "sci-fi" to some extent).

Having a girlfriend is REALLY hard, but it's also way more awesome than he'd thought it was going to be. This story is NOT CRACK. It's a serious Claptrap X GLaDOS story. For real.

What would happen if Wheatley and GLaDoS were finally human?

Short story of a man who learned what happens to people who cannot repay their debt to Teiai even if they would work their whole life.

Trouble at the Aperhoof Science Enrichment Center: personality sphere Spike needs to find somepony to test the portal gun, or he's in big trouble. But due to some errors, all the test subjects in cryosleep are in no fit state for doing anything. Luckily for Spike, he's got one pony left who has a great testing record.

Amanda on Sevastopol with a portal gun, everybody's favourite sarcastic core guiding her, the xenomorph, working joes, and... SEARCH MODE ACTIVATED (yep, those pesky little sods. Also based on a dream I had prior to writing It Takes Two.

The Illusive Man sends Shepard to investigate a missing Cerberus cell. Her team becomes trapped in the facility and must outwit a hostile AI in order to escape. But when they finally get back to the Normandy, they find the ordeal is far from over...

What would happen if the Half-Life protagonist were to meet the Portal protagonist? In the broken streets of downtown City 17, this is what happened. Rated T, for violence.

Wheatley remembers his before. His humaness. An Epilogue of sorts to The Threat Underground

GLaDOS lurks underground near a growing city, only a few know the true threat she is. Our main crew will have to delve into their own memories and venture underground to defeat GLaDOS. The sequel to The Curse Of The Cure
