This video is interesting to say the least. The voice acting makes me think Army of Two is supposed to be a comedy, while the eye candy makes me hope that this is real-time game footage. What's more interesting is the fact that AoT is the baby of Alain Tascan. Remember him? He's that guy from EA Montreal that says Gears of War has no innovation.
If Army of Two can somehow survive the backlash Tascan has created for himself by talking smack about Gears, then more power to the man. But, he doesn't bring co-op to the next level, I can't help but think he will be eating his words.
