Basically it's an Anti-Terrorist Training Facility for HLDM. Four different situation areas with an observation tower in the middle. The crates do blow up with quite the affect. Below the map is a prison where you can see other players movements on two maps mounted on the walls. There's a combination lock to get in there though. The number is displayed as you go down through the floor of the middle building(40687).Shoot one of the maps and you can place other players in jail. Shoot the other map and you warp to that area. A few more secrest here and there. Hopefully people are having fun playing it.
