This mod adds Crossbows into Fallout New Vegas which can be created at the workbench. Also includes a custom store with a quest + voiced vendor! It adds in Gauss type ammo which you craft with energy rounds and lead.
Project Nevada is a mod aiming to make Fallout: New Vegas a more interesting - eventually more challenging - but surely more fun experience for you. Project Mojave is a massive overhaul fallout new vegas weapon mod split into multiple parts so that you don’t have to incorporate them all if you don’t want to.
The auto-gauss I generally get when I finish veronica's questline and is awesome.
