A perimeter fence, a sniper tower, a row of small sheds, a maze. Its just not very interesting as a game or eye candy, its not even a matter of needing to learn the maze you just have to plasma climb or rocket jump into the fenced off teleporter. Teleport to the sniper tower and camp. You will end up back in the maze just for something else to do. Bots play ok but why would you bother?

An exercise yard in prison would be more fun.
