plasma assault rifle:by donut
idea:not mine, got it from this guy who made a two betrayals mod
work:done by me
shoots:plasma (blue)
effects:all he pasma effects 
muzzle flash:plasma
everything else is the same(damage=same,model=same)

ok this is my first weapon mod.
all of the effect files (for example: "impact sand")have been put in the effects folder
so you dont have to worry about moving files (sorry if thats confusing).
im not sure if this gun works though cuz i couldnt test it because my sapien if being faggy and
doesnt want to load my scenarios (if someone wants to put up a tutoral or something to help us noobs with
sapien problems that would be nice)
im assuming you know how to organise your weapons
(if you dont just put everything into "halo ce directory/tags/weapons" item collection goes to "halo ce directory/tags/item collection/single weapons")
have fun with it and you dont have to worry about credit (although it would be appreciated)
