Again with some classics, today we have a small yet interesting map. As the name suggests the map is a small arena better suited for deathmatch/gun-game modes. However, you can't see the maze shaped arena that includes the weapons on the ground until you rotate one of the valves. Once you've done that, the entire upper sandy floor will move away from the center opening the access to the underground arena where you'll find the weapons.. The arena will (slowly) close again once the round is done.
The package includes both an auto-generated .nav mesh for CZ bots as well as .pwf waypoints for POD-Bots.
Note: Don't conflict this map with this map named 'de_arena' as well. And if you know the author of this map please tell me so I give credits for him.
