Very innovative!
One particular guy seemed to keep getting shot in the head though. Over, and over, and over and over and over by the sniper, who appeared to be on his team but on the opposite side of the terrain. Note the blue helmet? I also noticed they didn't seem to have ammo limitations.
It did get awfully repetative in some points, but a nice sense of rhythm throughout. Not really much more to say than;
Sweet!
