Simple, yet a bit more realistic mod than most. What it does? Simply allows you to remove any weapon you have in hand, except fists of course. But what's so special in it? It won't just remove your weapon from a keypress, but you'll have to wait for an animation to play, and then your weapon is removed and appears as a pickup in front of you, in case you still need it. But remember, the weapon pickup acts as a temporary pickup so it'll disappear after some time!
Oh, and some small texture-working I've made, nothing fancy, weapons are converted from Battlefield 3 by YourCreatedHell, I only slightly enhanced the textures. Tell me in comments if I should ask him permission to release those textures, and maybe give me some suggestions and feedback?
