Night! You have bungie pro! Render it. Look for one where the grenades didn't explode.
Yes i was thinking That maybe its like the halo 2 switch, (my theory was that in the game levels they cut (a whole diffrent halo 2, at E3 they had partly made delta halo and they forgot to get rid of that switch which moved a gondola (or something) at the time), and the one on high charity. I dont know if having one person jump down in co-op triggers it, because you respawn too fast to hear it.
Here's my plan: *Keep in mind that this is void if there is a death barrier* Two players (could do this with 4 players, much easier) go onto the side wall of the elevator that comes up when youve killed everything. One players stands on the other, and the player on the bottom slowly moves of the edge. This creates the effect of player 1 (bottom) falling, while player 2 (top) rests on player 1's head. This creates for 2x more that player 2 can fall. Player 1 dies and player 2 lands on the elevator (same one that comes up once you've defeated all the covenant). Repeat. Find switch. Switch it.
