Atrinik Classic is the current playable, actively maintained game. Its software follows one coordinated 5.x release line; the next-generation foundations do not yet form a complete public download.
Release status
Classic and next-generation software have different licenses and different levels of readiness.
The unified atrinik/classic repository is the supported GPL-2.0-or-later software line. The download below follows the release that matches the official server, with checksums for every file.
The independently released MIT Go and Rust repositories use evidence-gated provenance and provide foundations in development. They do not yet make up a complete game, so no next-generation download is offered here.
Atrinik Classic client
Every Classic release ships a portable Windows x86_64 client and a Linux x86_64 AppImage, together with checksums and an SBOM.
On the release page, download the file ending inwindows-x86_64.zip. Extract the ZIP, keep its files together, and run atrinik.exe.
Download the file ending in linux-x86_64.AppImage, make it executable with chmod +x, then run it. It requires x86_64 and glibc 2.39 or newer, for example Ubuntu 24.04 or newer.
Classic software is licensed under GPL-2.0-or-later. Maps, graphics, audio, and other authored content can carry separate, per-file terms; the website’s MIT license does not cover downloaded files.
Before you begin
Classic releases include a portable Windows x86_64 client and server and a Linux x86_64 AppImage client, which you can find on the release page. There is no macOS client and no published editor binary. Confirm the exact release notes before installing anything.

Next-generation availability will be announced through the project’s public development and release process when it is ready.
