Better Automatron Weapons
If you're in possession of the Fallout 4 Automatron DLC, you'll want to check out this excellent modification to the DLC's weapons.
The Better Automatron Weapons mods re-balances the weapons that come with Bethesda's add-on from March. Specifically, it tweaks the Tesla Rifle, Salvaged Assaultron Head, Mr. Handy Buzz Blade, and Assaultron Blade.
There are some big changes but there are also some smaller tweaks that offer improvements over the vanilla versions of the weapons.
The trailer below will give you a better look.
