Portal 2 Co-op Bots, Full Trailer
The cake, which was a lie, might be the offered reward at the end of this one. The creepy automated voice is back. The portals are back. The puzzles are back with new twists. Simply awesome. Portal was one of the most unexpected and amazing discoveries in gaming. Originally included in the Orange Box along with Half Life 2, Portal was more than a reason to buy the packaged game.
Now, the sequel is finally knocking on the door. Not only a sequel, but a full game offering - wait for it - co-op play. This trailer is the first official full trailer for the co-op play, featuring the co-op Bots and that lovely computerized voice. This was played for the crowd at Pax 2010 and again, is freaking awesome.
