Ok this is a mod for BloodGulch called extremglch
Changes are:

Rocket launcher shots are faster (for both the hanheld version and on the warthog)
Flamethrower flames last a little bit longer
Fuel Rod Gun shots have a longer lifespan
Pistol shots have some force and stun people when they are shot for a few seconds
Plasma Pistol soots some shrubs that float in the air, and when charged up shoots a small tree (for camoflauge and to hide in)
Plasma Rifle shoots slightly faster
Assualt Rifle shoots needler bullets that have a fuse for 10 seconds and then explode, also never runs out of ammo (never have to reload)
Shotgun shoots 3 floating plasma grenades that explode on impact usally
Sniper now shoots wicked sick covenet plasma sniper shots (kinda like halo 2), also can shoot much faster almost as fast as a automatic rifle (but you have to click the shooting button every time)
Frag grenade is dropped like a mine does more dameage a bigger explosion and radius and has a 20 second fuse
Plasma Grenade is now thrown horizontally and explodes on impact (if thrown against a wall it bounces of and floats in midair)
