While playing Crota my friend saw ammo on the bridge, Crota was rotating the other direction so he went out for it. The rest of our team saw this from inside the crystal room. As my friend went for the heavy Crota glitched and changed directions. All we saw was Crota teleport in front of my friend, hear a rather high pitched scream and the ever famous "Guardian Down" this started the ever famous line from our raid group. Don't be trash, and Don't get ammo from under Crota's foot. We still haven't let him forget it.
