I remember playing couple years ago on a barn map where there was straight line, on one end there was a barn from where zombies would come from and on the other was a house where survivors would spawn in. And military map was quite small, i remember there were 2 or 3 baracks, 2 sniper towers and mostly empty space or tents. And i think you could call in a chopper on top of one tower. If anybody has links or files of those maps please send me a link to it because i wanted to play them with my friend but i cant find them anywhere in workshop.
