NVForever
An open-source, clean-room reimplementation of the Fallout: New Vegas engine, in the
spirit of OpenMW. It runs on the data files of your own copy of the game; it ships no
Bethesda content and contains no Bethesda or Gamebryo code.
NVForever is not affiliated with or endorsed by Bethesda Softworks, ZeniMax Media,
Microsoft or Obsidian Entertainment. See LEGAL.md.
Getting started
- Own and install Fallout: New Vegas (base game; DLC optional).
- Download a build from the releases page
and unpack it outside the game folder.
- Run
nvforever.exe (or ./nvforever.sh on Linux) and point it at your game folder
when asked.
NVForever never writes into the game folder. Its settings, saves and logs live in
Documents\My Games\NVForever.
Mods
- Mod Organizer 2: add
nvforever.exe to MO2's executables (the drop-down beside
Run, then <Edit…>) and start it from there. It loads the plugins ticked in MO2,
in MO2's order, and the game folder MO2 manages. See
docs/mod-organizer-2.md.
- Without a mod manager: put the mod in the game's
Data folder, then turn its plugin
on in Documents\My Games\NVForever\plugins.txt with a * in front of its line. The
order of the lines is the load order. NVForever keeps its own list, so the original
game's mod list is not changed.
Mods that need NVSE may not work yet: NVSE plugins (.dll) do not run in NVForever.
Building from source
Needs Rust and Python 3.11+.

Report bugs and differences from the original with the
issue forms. Crash

Contributing
Pull requests are welcome. Read CONTRIBUTING.md first: the clean-room
rules there decide what can be merged.
Support
NVForever is free. If you'd like to support it: ko-fi.com/lootjunkieazza.
Donations buy nothing extra; you still need your own copy of the game.
