I'd help ya, but you're gonna have to beat it solo to get the "A Monument to All Your Sins" achievement anyways. You should just go for it solo, just take your time, and carry a plasma pistol at times. I'm tellin ya, the plasma pistol shield drop then headshot will save you so much time, I dispatch every elite with it or an assasination. My other favorite trick is on the ONI level, grab the rockets after you take out the two wraiths, give the rockets to some douche bag marine and make sure he rides shotgun in the warthog. For some reason he'll have heat seaking rockets and all you have to do is drive throuhg the level and let him blow the hell out of everthing!
Thanks for the advice. I will use that wisely. Would you like to join my party sometime?
