Arctic Camouflage is a usable weapon camouflage for multiplayer unlocked by default. It can be utilized to much effect on arctic themed maps such as Derail, Sub Base, and Salvage. The Developers at Infinity Ward emphasized the care they put into perfecting the appearance of this camouflage, although It is unfortunately often neglected in favor of later unlocked camouflages.
The camo is also used several times by allied factions on their weapons: most commonly on the M14 EBR, but occasionally on the MP5K. Soap uses an M14 EBR with this camo on "Cliffhanger", Roach uses an M14 EBR with Arctic camouflage on "The Gulag", and along with Price on "Contingency". Members of Task Force 141 also wear various arctic themed clothing, though they bear little resemblance to the Arctic Camouflage pattern itself.
