This is one small map with a lot going for it. The layout wraps around itself quickly, thoroughly well connected with a simple and effective aesthetic. The top floor is where you want to hangout and try to control the level from. This is not as easy as it first looks in games with well matched players. There are a number of jumps that speed up the game play and action, like the one to the Railgun over the central pit. For the best results against bots load up two of them on Nightmare.
Great small map, grab it for sure.
