Assassin's Creed 3's Sharpshooter multiplayer character is going to require a NOS Energy Drink investment. Until January 31, 2013, the only way to obtain the Sharpshooter for AC3 is by purchasing a can of NOS and entering the code under the tab at the drinknos.com site.

The Sharpshooter requires only one NOS point to unlock, much like a similar promotion last year for Batman: Arkham City's Batman Beyond skin. Turns out AC3 and Batman have more in common than just their combat systems.
