Valve has released an extended Portal 2 cooperative trailer showing off more of the crazy, insane ideas that the developers at Valve have in mind.
As you already know, Portal 2 allows two players to tackle infinitely more complex puzzles than anything that was attempted in the first game, by forcing them to work together as two robot characters (a modified personality core and modified turret gun). From redirecting portals with lasers to working independently towards a shared goal, Valve is promising to “re-surprise” players with the sequel.
Here is the fun new trailer.
The Portal 2 release date is set for February 9, 2011 for PC, Mac (Via Steam), Xbox 360 and PS3 (The PS3 Portal 2 includes Steamworks).
