I got 19876 points on heroic on this map =D Firefight friggin rocks! One of the most memorable things that happend while playing it at the gamescom was taking out a wraith on this map! I don't believe it can get more awesome than mowing down rows of grunts, while charging at the tank with hammer brutes right behind you, your allies killing those hammers, taking out the wraith gunner with a plasma stick, jumping on the wraith and blowing it to pieces.
