The Plasma Shotgun is an item added by Matter Overdrive. It uses Redstone Flux (RF) to fire a spray of 10 energy bolts, each dealing 1.7 () damage on impact with a range of 16 blocks. Multiple energy bolts can damage the same creature at the same time, dealing up to 17 () damage per shot. Each spray fired consumes 2,560 RF and there is a 1.1 seconds cooldown between each shot.
Like other Matter Overdrive energy weapons, each shot generates heat which decays over time. Each shot generates 6 heat then multiplies the current heat by 4.2, and at 80 heat the weapon overheats, preventing it from being fired until it fully cools down. It can also be applied modules at a Weapon Station and can be enchanted with Overclock.
