Requirements:
-Windows 95 or higher (Another reason why PCs rule ^_^)
-DirectX 5.0 or higher (You can probably find this on download.com if you need it)
-32-bit TCP/IP support (You probably have this)

Files:
-SM.ZIP: (REQUIRED) Program itself, readme, and maps
-ATTACKS.ZIP: (REQUIRED) All of the artwork
-ASH_CO.ZIP: Midi files
-WAV.ZIP: Wave files
-MAPS.ZIP: Two extra map files

The first two should be unzipped in some directory, and the second two should be unzipped in a subdirectory called 'sound' (no quotes). Have fun!
