A survival map for Left 4 Dead.
This is a survival map for Left 4 Dead. There is a large arena-like area in the middle, which is surrounded by four rooms. The rooms are the intended defensive areas. Press the radio button and prepare to fight the horde. Do not go crazy with your weapons because ammo runs are difficult.
