Combat Arms is a modern first-person shooter online multiplayer game, free to download & play ~ GI-Game

Combat Arms free gameplay is similar to commercial games such as Counter-Strike, Ghost Recon 2 and Call of Duty. The game offers many different modes of free play, including One Man Army, Elimination, Capture The Flag, Search and Destroy, Elimination Pro, Last Man Standing and variations with objectives, as well as multiplayer co-op called Fireteam mode and Quarantine mode.

Combat Arms uses a player ranking system based on total experience, using common military ranks that players can obtain. Completing objectives, killing other players, and levelling up one's rank gives the player money in the form of Gear Points (GP), which can be used to purchase new weapons and accessories. All items purchased have a time length of anywhere from 1 to 90 days, after which the gear is deleted from the players inventory.

Sometimes players can buy Permanent weapons with GP. Players can also purchase equipment from the Black Market (also known as Nexon Cash Shop) using NX that are bought with real-world money. Primarily, the Black Market equipment is cosmetically different from regular shop items and has no rank or level requirement that many of the free items require. There are some items that may be obtained only through the Black Market, including permanent weapons.
