I has new ideas: Random Gun - Shots random projectiles
Mini nuke MOUNT - Just like Chinese water torture :D
DTS pong - Should have a command that enables you to set the DTS file for the pong projectile.
Scoped Magnum with Rocket Fuel inside the bullets - To freeze people
Ice Rambo bow - To go Rambo, Magic style
Implosion RL - To suck vehicles, and/or people inwards
