Valve, creators of best-selling game franchises (such as Left 4 Dead, Counter-Strike and Half-Life) and leading technologies (such as Steam and Source), today announced Portal 2 for shipment this coming holiday season.

Portal 2 is the sequel to 2007’s Portal, which won 70 industry achievement awards¹

Man. And it comes with co-op.
