Remember that game called Portal, the one developed by Valve Corporation, the one with the amazing physics magic and fabulous gameplay unlike essentially anything else you've probably ever seen!? Portal! The only things you really had to watch out for in the first one were murderous turrets and some falling spikes - and you were only one jamming portals into the environment. Now it's a whole 'nother game going on - co-op mode - Portal 2! This game comes out April 19th 2011 - that's 11 days from now!
