just in a game where some guys where trying to copy that worm guy and each time i threw the EMP grenade to the wall from the room they where in , i would destroy all equipment except the thropy system lol.
i kinda screwed me out of some easy war machine kills.
I don't think so. Remember that the EMP blast can go through walls and floors. If you are running engineer, toss the emp grenade just outside the room or building. This way it can't be taken out by the trophy system.
