You know, I'm planning a jail map as well. I'm planning on calling it Jail_Tech. Ive already drawn a blueprint and planned programming and everything! It will be the best map ever!
Can I? Yes I can indeed. I've already made 3 custom maps for practice. The only thing I'm having slight trouble with is the ammo stuff, but I'll work on that later. The map wont be done for awhile since I'm going to be away all summer, starting in two weeks.
