Twelve Thirteen

1213 is a freeware game in three parts by Ben "Yahtzee" Croshaw. Yes, it's him again.

Somewhat inspired by Flashback with some System Shock thrown in for good measure, 1213 is an action-adventure platformer complete with gun combat. Not bad for a game engine specifically designed for point-and-click adventure games. The title character, 1213, manages to escape the cell in which he has lived for as long as he can remember (Which isn't that far back) into something much worse.

As with the Chzo Mythos games, Yahtzee made a special edition of 1213. Originally donationware, it is now free to download.

Tropes used by the game:
"Westbury:"
 * Advancing Wall of Doom: 1213's entire perception of reality breaks down on several occasions, leaving you to keep him ahead of the breakdown.
 * Subverted. The inky blackness doesn't kill you, and doesn't advance on its own, only advancing when you reach a certain point.
 * Apocalyptic Log
 * All Just a Dream: Word of God suggests this as a possible interpretation of the game. But he also points out that it is probably not the case.
 * Attack Drone: Security drones, one of the tougher regular enemies in the game (Out of a pool of three).
 * Back Tracking
 * Bandaged Face
 * Bottomless Magazines: 1213's gun never runs out of bullets, while the same applies for the security guards.
 * : The horrible truth learned just in time for the player to realize just how badly every last source of hope has been destroyed.
 * Conspicuously Selective Perception: Guards will only shoot at you while you're on the same level as them, completely forgetting about you as soon as you drop out of their limited vision. Zombies only move in similar circumstances.
 * Corrupt Corporate Executive: In a sense, Westbury.
 * Otherwise subverted by Westbury's


 * Death Course
 * Downer Ending: And how. Even the comparatively silly hidden ending is equally depressing when you think about it.
 * Not really.
 * Edge Gravity: While walking, you'll stop at a ledge. Run, and you'll just run right off. There's even a Lampshade Hanging at the beginning of the game, when Westbury says "Don't worry, if you keep walking you won't walk right off the ledge. That would be silly, now wouldn't it?"
 * The Faceless: 1213 and the rest of his brothers and sisters all wear full-face masks
 * Heal Thyself: Showers can cure bullet wounds, zombie bites, being stabbed, electrocutions, heart conditions brought upon by sheer exhaustion, and painful landings.
 * Insecurity Camera: Mostly averted; most cameras are decorative, and only two will impede your progress if they see you.
 * Insurmountable Waist-Height Fence: Hundreds of doors, few accessible. Pretty much every elevator fails to respond to 1213, requiring him to haul himself between floors.
 * The Ishmael: 1213 towards Westbury.
 * Late to the Party
 * Mad Scientist: Westbury, according to Yahtzee's commentary.
 * Mission Control Is Off Its Meds: Westbury, Westbury, Westbury.
 * Nice Job Breaking It, Hero: By generally shooting everything that moves, 1213's considered a threat by the crew of the facility, which is a damned shame, considering what his purpose is...
 * Not to mention . Oops.
 * Nobody Poops: Shower blocks exist, barracks exist, there's even a small mess room and an entire food court, but not one toilet.
 * They could very well be behind those doors in the background.
 * Ontological Mystery: Stop me if you've heard this one: you awake in a room with no memory. Through exploration, you learn a backstory of horror, and ultimately fight to liberate yourself from your condition of ignorance.
 * Yahtzee happily lampshades this in the special edition commentary.
 * Precision F-Strike: As demonstrated above.
 * Puzzle Boss: The final boss.
 * Redemption Equals Death:
 * The Reveal: Maybe he could've done something differently if he hadn't been brought up to speed in the very last scene... but maybe not.
 * Scary Shiny Glasses: Westbury.
 * Take That: In the second episode, Croshaw included a "sprint" function, which allows 1213 to run faster at the risk of making his heart explode, by request of the fan-base. He then did not include a single puzzle in the game that requires the faster speed imparted by the sprint function.
 * Tastes Like Diabetes: In-Universe
 * We Will Have Perfect Health in the Future:
 * You Wake Up in a Room
