When Valve launches its new download-only Counter-Strike game next year, 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.

VALVE ANNOUNCES ARSENAL MODES FOR COUNTER-STRIKE: GLOBAL OFFENSIVE (CS: GO)

September 22, 2011 - Valve, creators of best-selling game franchises (such as Counter-Strike, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today announced the new game modes for Counter-Strike: Global Offensive (CS: GO).

Targeted for release via Playstation Network, Xbox Live Arcade, and Steam (for PC and Mac) in early 2012, CS: GO will expand upon the team-based action gameplay that it pioneered when it was launched 12 years ago.

Arsenal Mode is based on the popular Counter-Strike: Source mod Gun Game. "Arsenal: Arms Race" and "Arsenal: Demolition" add eight new maps and expand on the classic Counter-Strike gameplay.

Valve is working directly with creators of Gun Game to create Arsenal Mode. "We are excited that Valve reached out and is working with us to ensure Arsenal Mode is the best version of Gun Game.", Michael Barr project lead of Gun Game.
