A Quake III Arena port designed for running in pure JavaScript pre-ECMAScript 2015 (no WebAssembly). Simply open the link below, click the red icon, and select all the PK3 files and q3config.cfg (optional); all files will be loaded and booted automatically. If you have the commercial version and you want to play it, you need to have the Point Release 1.32 version, this means than you need to have and select at least the following files: pak0.pk3, pak1.pk3, pak2.pk3, pak3.pk3, pak4.pk3, pak5.pk3, pak6.pk3, pak7.pk3 and pak8.pk3. The multiplayer mode is not available in this project, for multiplayer check the original project link at the bottom of this document.
