The AmazeBreak is a vanilla jailbreak map. Jailbreak, if you don't know, is a Gmod/Minecraft/whatever gametype where there are prisoners, guards and one warden. The Warden gives out commands, the guards must make sure those orders are followed by the prisoners, and the prisoners must find a way, somehow, someway, to either escape or kill all the guards. The guards (The guards include the warden) win if they kill all the prisoners WITH A REASON TO, or if the timer (which is not included in the map) reaches zero and none of the prisoners have escaped.
It is good to note that this map is WIP, and is very new, and thus is very barren. I can't even get the game to spawn you in the spawn area! ( D: )
By the way, did you know the prison is under water!:)
