Counter-Strike: Global Offensive, it'll add several "Arsenal" modes to the multiplayer FPS. The Washington-based developer has announced a partnership with the creators of the popular "Gun Game" mod, on which Arsenal is based.
In Gun Game, players start with a simple gun and then gain access to more powerful weaponry as they score kills. The Arsenal "Arms Race" and "Demolition" modes will collectively add eight maps to CS: GO, and "expand on the classic Counter-Strike gameplay." Beyond its Gun Game lineage, we haven't yet seen how Arsenal mode plays out. We'd bet on there being quite a few dead terrorists by the end, though.
