This is the first official Black Talon DM arena map. Fast action paced rounds similar to fy_iceworld, bt_arena throws a few twists here and there. Four sniper towers surrounded with glass make for some wild sniper battles, while down below bridges collapse, walls break down, and chaotic gun fights happen in the water.

If you like this one, be sure to check out the night time variation bt_arena_night.
