View source for GAMES:X-COM: Terror from the Deep

===CD-ROM Version===
You will need to mount the CD for installation and also every time the game is played. Run ''INSTALL.EXE'' found on the CD and they will install by default to ''C:\MPS\TFTD''. Make sure you mount the CD back to the same drive letter you installed it to, or else it will complain about a missing CD. Alternatively, you may want to edit the BAT files yourselves if you decide to give it a letter change. Just search for the drive letter you installed from and change it to the letter that you will mount it to.

The affected files will be (assuming that you installed it to the default path) ''C:\MPS\TERROR.BAT'' and ''C:\MPS\TFTD\TERROR.BAT''.
