Click on the download button and save the 20.9 Mb file to a convenient place on your computer (such as your desktop). Then run it from there to install Academics 3D. It will run through June 2004, and then stop. It includes the core technology, one 3D Game (Patriot), Foundation (simple 2D non-game), and a very short subject about the history of the American flag. Some of the documentation is out of date, and the game levels in Patriot have not been fully tested or polished (some are known to be broken).
