It runs under OSX 10.3 (under X11) and also Windows, Linux and Unix - The game is free and very popular - the Windows version 38 has been downloaded more than 312,000 times since it was released 34 days ago. Though the minimum system requirements are not mentioned on the web site, I've found it requires at least a 16 MB (or more) video card and a G3 (or faster). Scorched 3D is a 3D version of Scorched Earth - and it has great OpenGl graphics. Version 38 of Scorched 3D was just released yesterday I've been playing since yesterday and it's worked great.
