Plasma shotgun shells: Upon getting level 6 of one of the shotgun shell upgrades(Forget which one) You can reasearch this. 700 of every science pack. Projectile power: ∞ Range: 45. How it works: Each projectile fires projectiles at every TARGET in sight, including trees, machines, biter bases, but not including mk4 construction robos from bob's mods (with my expierience.
