NVForever

OpenMW-style engine for Fallout: New Vegas written in Rust, running on the player's own game data. It loads plugins in Mod Organizer 2 order and implements xNVSE, JIP LN and other script-extender functions natively instead of loading their DLLs; builds so far are pre-releases.

nv-rs

Fallout: New Vegas

A new 64-bit engine for Fallout: New Vegas in Rust, produced by translating the original program function by function and checking each piece against it, then rebuilding memory, threading and rendering natively. It loads the game's plugins and assets from the player's own install; the only published build is an early experimental viewer.
