Uzi was removed on purpose since I realized that restoration was silly and unnecessary. 10mm SMG already exists in V13, restoring Uzi was a bad decision on my part. Forgot to remove the code for spawning it and ammo for it in V15 though, whoops. Thanks guys. It is planned to allow player to trade between knockback and no-knockback versions of sledgehammers via in-game customizing, I just haven't added it quite yet Personally I hate knockback, I think it's a stupid annoying mechanic that ruins HtH gameplay. Can you clarify about the items not stacking ?
