Map type: the single
Very difficult map which belongs to the Kill All of Them type. The player appears in a small dark room. The task — to interrupt all zombies who will appear indoors. And we will be helped with it all by a favourite small lamp which will give us a little light in the most full darkness. Prepare for difficulties because there is a lot of enemies.
