I recommend not using night vision goggles. The darkness this map has combined with the flare gun and a thick fog is just something you have to experience. Just relying on one source of light or waiting for the enemy to fire to expose them selves is something I haven't seen with any other maps yet. I really had a blast playing on this map!
