Elcor soldier: they don't carry weapons, instead their weapons are for their powers. Right bumper would be to use the gattling gun, which plays out like a geth spitfire with a max of 500 rounds, left bumper would be to use the rocket launcher, which is like two to three times as powerful as a frag grenade and gets a max of 5 shots, the Y button is to activate a new power that increases damage resistance by some amount and increases movement speed by up to 150% (this is an elcor, it's still going to be ridiculously slow). And since elcor are so large and heavy, they're immune to instant kill attacks.

Of course, to balance things out, they're slow (feel like I should keep pointing this out) and they can't even take cover
