Instead of a human test subject, Portal 2 ‘s protagonists are a pair of adorable robots. Don’t worry if one of them is flung into a wall, or falls off a cliff, or is otherwise burned, crushed or mutilated by Aperture Science’s many devious testing facilities. They’ll come back to life.
Watching this trailer does give you a glimpse of just how complicated playing Portal with two players — and two independently-controlled sets of portals that ruin everything you know about Euclidean geometry — will be. Make sure to pick a partner who won’t stab you.
Valve representatives said at PAX that the single-player mode of Portal 2, which will be released for Xbox 360, PlayStation 3 and PC on February 9, will be twice as long as the original 2007 game’s campaign. The co-op mode will also be twice as long.
