Changes the weapons, but has some frustrating aspects. With a little more work, it could become an excellent modification. The only thing this mod does is change the weapons. Actually, that's fine, the problem is how they work. Worse, you have no idea how many bullets you have in your current clip, so even though you ammo counter shows you have more bullets, your next shot could force a reload.
Damage seems very light as well.
The shotgun is amazingly ineffective, even at close range. Little difference between the rifles other than how they are modeled. The weapon models still need a lot of work. Sound was adequate. Some of the weapons didn't quite sound very convincing as firearms.
