Battle Rifle, though I never really relied on it, I'll take it if it's there or I need something more precise
Plasma Rifle (Repeater was pointless and impractical)
Magnum (Auto-mag was fun but weedy, I favour a 45. (I know M6's are 50.'s)
AR (I did however like the M7S in ODST though...)
Carbine all the way, never felt the need for the needle rifle
Brute shot, the original, deadly, cultured and not annoying as heck. Also, It's pointy.
Hammer, so I can say "Wammo!" every strike.
Rockets, because Booooooom that's why.
