📋 About This Mod
ALEX'S COPPERHEAD ASSAULT PLATFORM
Alex's Copperhead Assault Platform aims to bring a lore friendly AR-15 / M16 Platform rifle to the Commonwealth Wasteland, while maintaining the essence of a true weapon platform. There are many parts to the platform, and they are all completely interchangeable between all variants of the rifle. You can customize your rifle to match your playstyle effortlessly. Shotgun, Sniper, Submachine Gun, the classic Assault Rifle, and many more.
All parts of this platform are completely interchangeable. You can freely swap between receivers, magazines, stocks, barrels, and many more. There are also several Uniques to find, provided you can decipher the clues...
This is meant to be a Late Game weapon, and spawns even after the vanilla Assault Rifle Does. It is meant to help you fight against the infinitely increasing health of your enemies in the Commonwealth for just a little bit longer.
Contains full levelled list integration, thanks to a_blind_man's injection scripts. You'll find variants of the rifle on Mid-High Level Gunners, High Level Raider Bosses, and High Level Vendors
While uncommon, the Copperhead Assault Platform and its variants were used by United States Military Forces before the Great War. Each variant has its own story to tell, but the platform as a whole traces back to the late 1950's with the Cottonmouth Marksman Rifle. In the post-war Commonwealth, the rifle finds its way into the hands of Raiders and Gunners via caravans from the West. However, rumors stir that the Gunners have gained control of a manufacturing facility on the outskirts of Boston from the pre-war era. While unconfirmed, time may reveal more information on the matter.
