Divers, all know what the effects of compressed gas are underwater. Diver training teaches that lungs would burst from over-inflation. This principle is key to the effectiveness of the WASP Injection System.
This weapon injects a freezing cold ball of compressed gas, approximately the size of a basketball, at 800psi nearly instantly. The effects of this injection will drop many of the world's largest land predators.
Doesn’t look that useful in a fight. Further, such an odd weapon would guarentee you would be charged, even if in the right. Better to stick with a pistol.
