M32 Multiple Grenade Launcher
This semi-automatic monstrosity is capable of firing six 40mm grenades in less than six seconds; 18 in a minute. That's just the tip of the smoking barrel. It also shoots HUNTIR rounds, which float to the ground via parachute and capture aerial video footage, as well as HELLHOUND rounds-extremely powerful projectiles that can be fired from 140 yards and obliterate everything in sight. God damn. Check out the shooter's reaction when he unloads six rounds into an empty truck from over 100 feet away.
