Portal 2/Trivia


 * Artifact Title: almost happened.
 * Fan Nickname:
 * "Portal Kombat": The release date coincided with that of Mortal Kombat 9's; the temptation to switch out the "M" in "Mortal" for a "P" proved to be too great. It doesn't help matters that both Noob Saibot and Scorpion have fatalities involving creative use of portals, and the former's babality even involves portals.
 * Developer Nickname:
 * Freeze Frame Bonus: The trailer for the Perpetual Testing Initiative contains (incredibly small and barely distinguishable) footage of Meet the Pyro.
 * Hey, It's That Voice!!:
 * Both GLaDOS and the proper Turrets (as well as ) are voiced by the same person as in Portal.
 * Stephen Merchant (writer of the original The Office) is Wheatley.
 * He's also in Hot Fuzz briefly as P.I. Staker...having problems with birds.
 * J.K. Simmons (J Jonah Jameson) is the voice of Aperture Science founder Cave Johnson.
 * He's also the professor in the Farmers Insurance commercials (Bum-ba-dum ba bum-bum-bum!)
 * Dee Bradley Baker voices the co-op bots.
 * Literally everything save for the Male Announcer and those above is played by Nolan North.
 * Internet Counterattack: Relatively minor compared to most examples, but some people were not happy with the results of the Potato Sack contest on Steam, and wrote negative user reviews on Metacritic just for that.
 * She Also Did: Most of the animation of Personality Cores was done by Karen Prell, AKA Red from Fraggle Rock.
 * Sure Why Not: Red emancipation grills, originally from Portal: The Flash Version. The blue plasma walls are also similar to official Hard Light Bridges.
 * Urban Legend of Zelda: Despite the obvious contradiction of J.K. Simmons, Erik Wolpaw has had to confirm that these rumors are false.
 * What Could Have Been:
 * A very early version of the game, based on an internal prototype called F-Stop, was supposed to be a full prequel to Portal, taking place decades before the main game and focusing on Aperture's origins, with a brand-new game mechanic that Valve absolutely loved - and without a single portal in sight. Testers, on the other hand, weren't so happy about the concept, insisting on having Chell, GlaDOS and the Portal Gun in the sequel.
 * Valve released short Aperture Science videos showcasing the various new gimmicks, including Aerial Faith Plates, the Gels, the Thermal Discouragement Beams, and the Pneumatic Diversity Vents. The last is completely absent in the final game. Although the player does travel through vents at several points, they're cutscenes, not a gameplay element.
 * Originally there were meant to be more personality cores the player would interact with apart from Wheatley. The audio commentary explains they scrapped them because there were too many, and there wasn't enough time to give each one a decent amount of characterization. Some of the cores got recycled as
 * Some unused dialogue found in the Portal 2 files suggests that Cave Johnson  much like his Memo suggests. In fact he   similar to the companion cube and would be plugged into a wall. In order to get through to the next chamber you would need to disconnect and kill this cube.
 * Originally Wheatley had a different voice actor (Valve animator Richard Lord). Though still British and with similar dialogue, Wheatley seems like a very different character from how he is in the final game. You can checkout the original Wheatley here.
 * If Stephen Merchant turned to be unavailable, Valve were in talks to have Richard Ayoade - best known as Moss from The IT Crowd and Dean Learner/Thorton Reed from Garth Marenghi's Darkplace - play Wheatley instead.
 * The co-op mode was originally going to have another woman named Mel work alongside of Chell. She ended up being replaced by Atlas and P-body after someone pointed out that play testers tended to die a lot.
 * One of the gels was supposed to allow you to ignore gravity and walk up walls. It made playtesters sick. It was one of the three "paints" in the indie game "TAG - The Power of Paint", that inspired the gel mechanic. The other two, "Fast" and "Jump/Bounce", made their way in the game with the new Conversion Gel.
 * One player found that the Peer Review DLC secretly replaced the unused fourth gel with a new "Reflection Gel", which would reflect any lasers directed on to them similarly to a Redirection Cube. It was most likely cut because the cubes are far more versatile and flexible than the gel when it comes to devising puzzle solutions.
 * Cut sound clips seem to indicate that the original plan was not to have a separate announcer narrate the tests before GLaDOS's revival, but recordings of GLaDOS with the exact same lines. Notably, these lines bear a stronger resemblance to her lines from early on in the first game (i.e. more cold and robotic) than the rest of her lines, suggesting a sort of audio continuity.
 * According to The Final Hours of Portal 2, there were several different ideas for the ending, including one where Chell would say one word, "yes", to end the game, and another involving a duet between Chell and G La DOS.
 * Portal 2 was going to be a game without portals.
 * In the script files for the game, there is a lot of unused dialogue, some of it pretty funny.
