[edit] How to Setup

Note that these two games are very popular, thus there are various version of the program for DOS, and even a special collectors edition for Windows. This guide describes the CD-ROM version of the two games only. When the disk versions are tracked down, more information will be added.

[edit] 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 CDs and they will install by default to C:\MPS\UFO and 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\UFO.BAT, C:\MPS\TERROR.BAT, C:\MPS\UFO\UFO.BAT and C:\MPS\TFTD\TERROR.BAT.

[edit] Playing Terror from the Deep without the CD-ROM

On the root directory of the X-COM: Terror from the Deep CD, there is a directory \HARDDISK. Executing the installation file there will install the game so that it does not require the CD to play, however the instead of an introductory and game-end video it will be a slideshow instead.
