Portal 2 co-op gamplay footage hits PAX
Nine minutes of co-op gameplay for Portal 2 has come out of PAX, and it's looking pretty sweet.
As the video explains, the two-player co-operative mode allows both players to control separate portal guns and also allows players to use each others portals as necessary. Both players take on a different colour to help distinguish between the two sets of portals.
Check out the footage below. There's some co-op shots over at RPS.
Portal 2 is due for release on February 9.
