Yeah, this is more suited to the Reach forum but whatever. I'd personally want to see a Gauss Rifle.
Weapon Type: Support (Flamethrower, Machine Gun Turret, etc.)
Ammunition: 10 Shots, non refillable.
Rate of Fire: 1 shot per second and a half.
Damage Dealt: 2 shots-Infantry, 2 shots-Light Vehicle, 4 shots-Tank.
Impossible to implement into ODST but whatever...
