(Fixed the article by correcting the mistakes done by the previous author(s) who indicated that the demo is a DOS application which it isn't. Provided general directions on how to run it on modern versions of Windows.)
This demo features three levels from the actual game. 2 Allies and 1 Soviet mission.
To run it on modern versions of Windows extract the contents of the INSTALL folder to anywhere on your hard drive. Like the retail version you need a thipx32.dll file from either Scorpio9a or CnCNet (demo does not support multiplayer, but requires this file) and Windows 95 or 98 compatibility mode.
