Shoot firstG 40

This is one of my favorite achievements in the game because they use Star Wars movie related phrases for most of the achievement names that fit the actions needed to unlock them. This one is most fitting and will unlock when you get the first kill in any of the game's multiplayer game types. Just rush to the enemie's side at the beginning of the match. Be quick on the draw or throw a well placed grenade and this achievement will be yours.
