Escape takes place on Alcatraz. The map is full size and every building is accurate to the real thing. There are 5 classes to choose from and there's an ammo shop with free ammo! The gameplay of the map is highly intense and difficult (tons of CQB). The map was not made by me, however. Jaff62 and Ash_Killer made the map, and it took them almost a year to do so! All I did was zombify the place, and that took me only 4 hours (which is the longest it has ever taken to work on a map)! The mere existence of this map couldn't have been without these two "architects", so kudos to them for making such an awesome map!
