Atlas and P-body prepare for testing in latest Portal 2 co-op trailer

We’re not sure that title could have been any more descriptive, because as you can see, the trailer above depicts Atlas and P-body preparing for testing. The implementation of co-op play in Portal 2 should be more than welcomed as it clearly would take the series to the next level – or down under depending on what kind of friend you play with.

Valve’s Portal 2 is set for a mid-April 2011 release on PlayStation 3, Xbox 360, PC and Mac.
