📋 About This Mod

Building on the Grunt and Cowboy Perk fix - No Weapon Left Behind - ESPless Scriptrunner mod by Gdhvd, this mod is meant to be the ultimate, most complete version of the Grunt and Cowboy Perk fix series of mods, extending the effects of those two Perks to all the weapons that Obsidian didn't include in Cowboy and Grunt due to technical limitations, and expanding the effects of Cowboy and Grunt to all weapons where it makes sense logically, thematically, and in terms of lore.

One version is for base Fallout: New Vegas (and all the DLC), and the other is for Tale of Two Wastelands, adding in all the weapons that the TTW creators overlooked, as TTW already makes quite large changes to the functionality of these two Perks.

Credit goes to Ghvhd, ChunksAhoy, and Bunslinger for all the work on their Grunt&Cowboy mods which inspired me to make this one. Seeing those mods on the Nexus was how I learned of the incredibly sloppy implementation of these Perks by Obsidian.

Generally, weapons were added to the two Perks due to 3 reasons:

- The "bug fix"/"we didn't include these due to technical limitations" variety; typically unique/variant versions of weapons that Obsidian didn't add to the Cowboy and Grunt FormLists due to those weapons being added to the game by DLCs, such as the (GRA) weapons, the Great Bear and Red Victory Grenade Rifles, the Medicine Stick, Tomahawks, and so on.

- Thematic consistency. Cowboys are often depicted in media wielding double-barrel and pump-action shotguns, bolt-action (hunting) rifles, as well as axes, shovels, and other outdoor tools. Same with soldiers and satchel charges, sniper rifles, flamethrowers, as well as automatic and pump-action shotguns.

If the vanilla Grunt Perk includes the . 45 auto Thompson submachine gun and M1911 pistol, both of which are WWII weapons, then it only makes sense that it includes the M1 Garand (Battle Rifle/This Machine) and Remington 870 (Hunting) shotgun, which closely resembles the Winchester Model 1897 and Model 1912 shotguns used by American soldiers during WWII.

- Lore. A lot of weapons were used by military forces in Fallout before the Great War, including quite a few that the player can see and use in Operation Anchorage in Fallout 3. The Operation Anchorage weapons include the 10mm Pistol and Submachine Gun, Sniper Rifle, Gauss Rifle, Missile Launcher, Flamer, Super Sledge, and Minigun. I didn't include any Laser or Plasma-based Energy Weapons, or the Fat Man, as those were all highly experimental prototypes that soldiers wouldn't have gotten much experience with before the Great War. Power Fists, Super Sledges, and Rippers were all used by the US military for various purposes, kind of like shovels. Those weren't always used for direct combat, but neither are knives the majority of the time.

But aren't Gauss Rifles experimental prototype tech?

Gauss weapons seem to be more
