A fusion pistol physics for those who like playing on BROWN, or rounds with the Fusionize script. Basically makes it stronger, dare I say crazy. :P
The primary fire is the usual major/overload bolt, and the secondary fire shoots the major dispersal bolt. Basically the damage amount is the same, however it also has splash damage, so be careful with distance.
Admittedly this idea is not completely originally mine. It's very similar to how the fusion pistol operates in the 9 Minutes 37 Seconds scenario.
While I can't stop you from using it as such, it's not intended for games that don't only have the fusion pistol, so keep that in mind.
