This is that glitch where a player appears to be stationary or stuck, not moving... but apparently is still playing in the game. A little like the "invisible player" thing I suppose. N7 Paladin playing Firebase Dagger, bronze, waves 10, 11.
But there are enemies just mysteriously dying in front of me like the Brute and then the cannibal, at 0:50 (nothing in feed) or the Brute and Banshee at about 3:40. Ha ha. Little difficult to "co-operatively" play when you can't see your team mates, ugh!
