Sattershot... A beautiful weapon. Easy in close quarters, especially in tight halls where the projectiles bounce on impact on things other than other players and vehicles.
UNSC- BR.... You expected something else?
Covenant- Beam Rifle, snapshot city.
Forrunner- Scattershot all the way!
Vehicle- Gauss Cannon Hog, Sprees and Frenzies coming out my bum every time.
