Mod adds almost all weapons and ammo from Vegas.
Including - Ballistic, Energy, Explosives and Melee Weapons and Ammo.
All weapons have their unique sounds. Retained almost all reload animations and some of them are "fitted" under Fallout 3. Mod also adds some weapon modifications, bit int's still experiment, for now.
All weapons can find as any other weapon, buy, find on enemies and etc.
