"X-Com: Terror from the Deep" is the 1995 follow-up to 1994's "X-Com: UFO Defense," created in six months when the publisher, MicroProse, decided it wanted to capitalised on X-Com's success. As a result, Terror from the Deep is almost the exact same game as UFO Defense, except for redrawn graphics and a different premise. Terror from the Deep is a DOS game, making it a good fit for the DOS emulator, DOSBox. It requires slightly different settings than the usual emulated game.

Skill level:


  1. 1

    Navigate to the DOSBox folder, then open "dosbox.conf" in Notepad. Press "Ctrl+F" and search for "Core" and "Cycles." Change the core variable to "core=dynamic" and the cycles variable to "cycles=40000."

  2. 2

    Make a note of where you've installed X-Com: Terror From The Deep. The default directory is "C:\TFTD." Open DOSBox, then type: "mount c:\TFTD" and then hit "Enter." Type "c:\" and then hit "Enter."

  3. 3

    Type "tftd" or "tftd.exe" to run X-Com: Terror From The Deep.

Tips and warnings

  • Once DOSBox is configured, you can run TFTD by navigating to the directory in Windows Explorer, right-clicking on the "tftd.exe" file and clicking "Run in DOSBox."
