For defender use the purple force barrier gauntlets (forget the name), Monte Carlo, and a shotgun, the super portion of that is stupidly easy, easier than all others, for the grenade part just wait for mayhem and use magnetic grenades For striker also rock a shotgun and Monte Carlo but use insurmountable skull fort for the double melee, lightning grenades and armamentarium, I have 3 "double kills" to go with striker until I get its enblem Striker is pretty much the same as voidwalker so it's not too bad
