Plays inside your own copy of Fallout: New Vegas, on your device, not in a browser tab. Opens github.com in a new tab.
How to play
Have your own copy of Fallout: New Vegas installed: the mashup plays inside it.
There is no release yet: get its code from its repository on GitHub and build it as its README says (it runs on Linux).
Install it as its page says. What it asks for is just below, in the list's words.
Start the game the way its page says: some mashups come with a launcher of their own.
What it asks for
Linux with Steam + Proton, Fallout: New Vegas 1.4.0.525 (Steam) without other ReShade/d3d9.dll mods, owned Minecraft: Java Edition with Prism Launcher, a Vulkan (DXVK) GPU, and git/curl/7z/unzip/JDK 25/mingw-w64 (i686) to build. No binaries are published.
