Rail Gun

A railgun is a device that, by using an electrical power source, is able to drive a projectile at much higher than regular bullet speeds, allowing it to penetrate through a person, and continue. Unfortunately, this effect also greatly increases the recoil. A small railgun required a strong mutant to wield, and the gun itself was necessarily heavy to help with the absorbtion of the recoil. A larger version of the railgun necessitated the Mammoth Mk. II, whose quadrupedal configuration was much better suited to absorbing recoil than the bipedal configuration of the Titan and Wolverine.
