Valve Software's upcoming first-person action/puzzle game Portal 2 won't make it in time for Christmas. However, gift-givers can still pre-order the game at GameStop and receive the exclusive “Custom Bots” for the game's cooperative multiplayer component (while supplies last).
The new installment takes players into new areas of the Aperture Science Labs and reunites them with GlaDOS. The game's two-player cooperative mode features its own campaign with new player characters, new chambers, and a unique story. Portal 2 is slated for an April 2011 release.
