Well... it's a physics model pack. Not exactly the best light you want to throw on your creation.

The slow-motion physics are OK, but since the monsters move just as fast as usual while you move at 1/4 speed, it's near unplayable in solo. The projectiles also move, relatively, too fast, and the bullets shouldn't have the missile contrail. Instead, give them something less obtrusive like the fusion contrail.

The AR mine physics are pretty good, and I can't think of anything to say about them except that you should have kept the current grenade function and make the fists create the mine instead, or something like that.

Overall, meh.
