(1) on delta halo, when you get to the part where you have to lower the bridge, there is a way to make the elites on the ghosts seem incredibly stupid.NOTE: THIS WORKS BEST ON CO-OP.
Okay, before you go to the part with ghosts, snipe(if possible) all the grunts on the turrets that you can see. then there should be a cliff next to you, a looooooong cliff. get near it then jump down the first ledge.
there should be a few rocks. have player 1 go out to distract the banshees. only one should come at him. have him jump over it and it will go FLYING off of the cliff.have player 2 step in and another ghost will come to him. have him jump over that one, and it will do the same. the last one should go towards 1st player and he can either jack it or make it go off (well, you can do this with all of them). the last two you should just blow up, cuz they can be a problem w/the wraiths.
(2) on outskirts, when you get near Sniper Alley, there should be a big pillar thing. look to your left and there should be a ledge just above a little rock somewhere. jump up on the rock, then jump on the ledge. you should be in a little hallway sort of thing where ther are no enemies. at the far end there should a little trash can sort of thing. you can either set that up for a jump, or use a grenade jump(recommended). when you get on top, there should be an elite(I think) standing on the bottom. make sure he doesnt see you, it will ruin everything(this is a good spot for killing).try to get a plasma onto his head. if you do, he will just stand there.no yelling,nomovement,hes just standing there. once it blows up,(if you have the sputnik skull, I WILL NOT SAY ANYTHING ABOUT IT)it will go flying into the air.
