Since E3, Valve has been consistently releasing more information about its GLaDOS-dominated puzzler, including gameplay videos and the release date. The trailers for Portal 2 have shown a stimulating single-player experience, but what about the multiplayer? Valve has previously discussed how multiplayer co-op would work in Portal 2, but had not shown any gameplay footage. At least, not until now. Check out the teaser video below:
Because there will be two players, there will also be four different colored portals used in multiplayer. While this opens up the possibilities of even more ingenious puzzles, as a color-blind gamer, it does give me a little concern depending on which colors are used. The original Portal used orange and blue portals that were easily discernible. But if say, green and red are the two new colors, then those who are color-blind will have some difficulty keeping track of the portals. A similar problem occurred in Call of Duty: Modern Warfare 2, where friends and foes were highlighted in green and red, which made it extremely difficult to determine who to shoot. Despite a petition from color-blind gamers, no changes were made to that game's color scheme.
Notwithstanding this, the game looks like it will be a ton of fun, so long as you don't play with one of your impulsive or temperamental buddies.
