Source, setup & reuse terms

Fast arena FPS with movement techniques, bots, team modes and a level editor. The official download currently offers 0.8.6; this is a mature project, not a newly released AI-made game.

Code & assets

Code: GPLv3+ project; preserve component licences
Assets: Official project describes the game as freely playable and modifiable under GPLv3+. Preserve individual asset notices and corresponding-source obligations; no per-asset redistribution audit performed here.

  1. Use the current official download, with hardware-accelerated OpenGL 2.1 and at least 4 GB RAM. No browser port is represented by this listing.
  2. Source builds and NetRadiant map editing require their separate official setup. Follow project/component licence notices; no local build verified.

A first idea: Try one small single-player arena change in a separate fork, then establish a modern-browser build before adding maps or network features.

Download brief

Source, setup & reuse terms

A browser port of the Cube 2 first-person shooter with multiplayer, maps and weapons. Its original web build is now a legacy experience, but the source shows how a full 3D arena shooter was brought to the browser.

Code & assets

Code: zlib
Assets: Art assets are CC BY or CC BY-SA; the upstream README says directories without a specific licence default to CC BY. Retain the original author credit and any share-alike terms. Mozilla branding is not included as a reuse grant.

Original licence notices ↗

What you need

Complete source and included game assets; historical Emscripten toolchain required.

  1. Use the pinned repository and its documented Emscripten/Cube 2 build setup; this is not a simple single-file web game.
  2. The project is inactive and its legacy WebAssembly/WebGL runtime may need browser compatibility work.
  3. Keep attribution for all art and verify any per-directory licence before redistributing modified assets.

  • This old project does not meet a modern AAA visual target; treat it as a substantial historical browser FPS source.
  • Preserve zlib and asset-specific terms; do not reuse Mozilla marks or external commercial game assets.

About these listings

Listing, price and licence information is upstream-reported, not our gameplay testing or remix permission. Recommended prioritizes reviewed picks, then source-reported released games with free access, imagery and strong player-rating evidence. These are discovery signals, not our gameplay quality score. Most rated uses sourced rating/review counts, not players. Device and engine filters reflect source reports; Godot is an engine, not a platform or quality certification. Unknown counts rank last. Price reports do not establish original-content rights or working gameplay. Curated source foundations are additional project guides; main search includes their matching entries. The listing count does not silently add or double-count those guides.
