Fallout: New Vegas - Project Nevada Mod

Project Nevada is not an overhaul, instead it's organized as a set of themed modules. Each module can address different aspects of the game and target different audiences, but they are also designed to work in conjunction. The vision is to allow players picking the modules they want and using them together with any mod they like, instead of forcing them to make the all-or-nothing choice. Some of those features are improved versions of already well-known Fallout 3 mods, like the Grenade Hotkey, Bullet Time or Sprint. All of them are rewritten from the ground up, with exciting new features like the support for several VATS perks in Bullet Time and support for throwing weapons with the grenade hotkey. Along with a plethora of other features.
