Portal 2! New Characters! Multiplayer! No Cake Jokes?

Good news for people who like interspatial travel:  Portal 2 is coming, probably for Xbox 360 and PC. Game Informer’s April cover reveals that the sequel to Valve’s cultish 2007 hit is real, and while the big reveal was short on details, Kotaku found some more information through GameStop’s listing for the game. So here’s what we know:

Portal 2 will have a multiplayer mode with its own story-driven campaign. This has to result in some mind-bending puzzles, as the original game’s objective — escape a science lab by shooting Point A and Point B portals in the walls and travelling between them — was twisted enough.

Portal 2′s single-player mode promises “a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers,” according to GameStop. GLaDOS, the deadpanning AI who guided you through the first game, will return, though in what capacity we don’t yet know. GameStop lists an October 26 release date, and while that’s subject to change, a 2010 launch seems likely. But its said — or perhaps triumphant, depending on your tolerance for memes — that neither Kotaku’s nor Game Informer’s coverage makes any mention of cake, or it being a lie. And if you don’t get that joke, then just don’t worry about it. [via Kotaku and Game Informer]
