A gear shredder is a weapon which fires discs at the opponent to tear them to shreds.
A Gear Shredder fires discs at the enemy these discs, generate a great deal of heat on the edges so they can melt through armor and even cause trouble while they are lodged in the target. Some version use Phase Energy to disrupt molecular bonds and slice through conventional matter easily. These alternatives are more costly in terms of energy and resources.
The 'gears' fired can take the appears of actual gears, discs or circles but the ammo fired is always circular.
