Its a small, simple, rather motion-sickness inducing physics file I made a while back that makes all the weapons fire loads-upon-loads of projectiles but there's no over-powering weapon (Well, the AR could be argued as being a bit over-powered...and the SMG is kinda crappy). For example, the SPNKR now has a clip of 4 and the rockets stop spewing smoke after a few seconds, but each rocket only does a 1/4th of the damage of a normal rocket (so you would still do the normal rocket damage total if all 4 rockets hit, although I threw in a slight randomizer, so your target might actually survive that 4th rocket). I also increased movement speed so that you can dodge the wall of death that people can spew out, but I was a bit over-zealous and now you can actually sidestep between rockets if you're quick and aren't throwing up all over your monitor.
I'll probably modify it and "fix" a few of the problems it had (the excessively-high movement speed for one, I think I pretty much doubled your walking and running speed), I feel like messing with it again.
