Combat Arms

Combat Arms gameplay is similar to commercial games such as Mission Against Terror, Crossfire, Counter-Strike, Ghost Recon 2 and Call of Duty. The game offers many different modes of play, including One Man Army, Elimination, Capture The Flag. During the 2009 winter season of the game, a special mode known as Snowball Fight was introduced, but was later removed. 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 leveling up one's rank gives the player money in the form of Gear Points (GP), which can be used to purchase new equipment. Equipment includes weaponry, weapon attachments, and accessories for one's character. Players can also purchase equipment from the Black Market that is bought with real-world money. Primarily, the Black Market equipment is cosmetically different from regular shop items and have no rank or level requirement that many of the free items require. In addition, some items may only be obtained through the Black Market. Items purchased typically have an expiry date, after which the gear is deleted from the player's inventory, though some can be purchased permanently.
