Deus Ex: Invisible War -
A rocket turret and two more Paladins patrol the next area. They'll drop a flamethrower and a mag rail. This Paladin is sparking because my spy drone didn't give him quite enough juice - yet. Note that knocking the power-armored Paladins unconscious results in their self-destruction. A pacifist technique? In my mind they are killing themselves -- but if you want an extra challenge, ditch the spy drone tactic on the power-armored Paladins from here on.
