Description How good are you with the gravity gun? In this map there are 8 difficulties (Easy, Medium, Hard, Advanced, Extreme, OMG Hard, OMG WTF?, Goreful), in each difficulty there are different changes to the map which are described at the bottom of the screen when you load up that difficulty. The .zip file has also come with a "fun" map which was made just for mucking around and having fun while killing zombies instead of dying all the time :D.
To play the fun map, go into console and type in: "map zm_fun" without the quotes.
THIS IS A LOW DETAILED MAP TO REDUCE LAG!
This map has not been compiled with HDR to reduce further lag for mass carnage.
The damage is only directed to the normal zombies, not the fast zombies or headcrabs.
