Based on campaigns.
God weapon-Pistol, no explanation needed
Overpowered sidearm-Plasma pistol, its supposedly a sidearm yet its superior to the plasma rifle and has an insta kill over charge for flood and grunts
Automatic plasma pistol-Plasma rifle, is it me or do these two do the same damage? And it lacks overcharge
Self contradictory weapon-The shotgun which cross maps flood, despite being a close quarers gun
Splish splash splosh gun-Rocket launcher and its huge splash damage
Anti infantry and vehicle sprayer-AR, you can spray at a back of grunts and kill all of them in 5 seconds, plus it brings down banshees and ghosts in a magazine
No need to pick it up gun-Needler, my favourite gun in the game but when you are surrounded by OP weapons why pick it up, with its long kill times and dependency on open areas with no hiding places or corners?
A vertical seasaw gun-The completely unbalanced sniper rifle that tears through covenant but useless against flood and vehicles
Scary ball-The frag grenade, you throw it behind a rock and next thing you know a bunch of grunts and jackals fly away screaming
Sleepy ball-The plasma grenade with its long kill times, enough for the elite or whatever to charge at you and kill you with your own grenade
Haxor gun-The warthog chain gun and its insta kills
Blind bullets-The scorpion chain gun and its inaccuracy
