The Wasteland Combat Update would be a themed content update, and completely free. The update would contain the following:
New weapons(pistols, rifles, melee, etc)
New mods for both new and existing weapons(Automatic .38 Receiver anyone?)
New Armors
New mods for armors
New Helmet types: Sturdy and Heavy Combat Armor Helmet, Sturdy and Heavy Metal Helmet. Standard, Sturdy, and Heavy Leather Helmet
Ability to mod the Blue Batting Helmet, Vault-Tec Security helmet, Army Helmet and Dirty Army Helmet.
Extra mod options for Metal Helmet and Combat Armor Helmet
Craftable ammo types
New enemies types
The Weapons, armors and ammo types would be added to the world, as well as weapon and armor vendors. The ammo crafting would be done at the weapon bench(I don't see a reason for adding another bench for the sole purpose of reloading ammo).
