Thank you for pre-ordering Call of Duty®: World at War! The M1A1 Carbine Rifle is a fast and powerful weapon that is normally accessible at level 65 in Multiplayer, but you can use it from Day One. To use the M1A1, simply join any Multiplayer game and chose the “Rifleman” class. Your “Rifleman” will have the M1A1 equipped, rather than the default loadout and this class is exclusive to pre-order customers.
