Valve was kind enough to fire me off some co-op photos of “Portal 2” from PAX. As per my conversations with Valve at E3, “Portal 2” will incorporate a co-op mode where two players assume the roles of robots armed with portal guns. This will be a completely separate campaign from the single player mode, and they promise it will be much more challenging in order to correct for the increase in portal potential. Sounds awesome, as always. I don’t mean to give Valve free press or anything, but these kids are unstoppable.
