The almighty LasGun. It is a fast, rapid firing railgun which uses fusion cells. It's accuracy isn't as great as plasma rifle's railgun fire, but it makes it up for it's random damage and random fire speed. (Everything about this weapon is random, depends on how high the fusion energy is, sometimes attacks once, twice or even 3 times in one click)
