The name "Nemirtingas" comes from Lithuanian, roughly translating to "immortal" or "deathless"—a fitting name for a tool that refuses to let DRM kill offline single-player gaming.
The tool is most frequently mentioned on forums like CS.RIN.RU and GitHub as a launcher that can trick certain UWP (Universal Windows Platform) games into thinking the user has a valid license, allowing them to run without the Xbox app or Microsoft Store authentication.
