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.

What you need

Official source repository and downloadable code sources linked; no immutable revision or installed-release/source match verified.

  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.

  • Official security notice: versions older than 0.8.6 must not be used to join online servers. Link points to the current official download, not an old binary.
  • External listing only: no Game Commons hosting, malware clearance, local playtest, partnership or automatic remix integration is claimed.
  • The displayed official media-kit image dates from 2011 and does not attest the current release.

Pinned README and licence statements inspected.

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.

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.
