Terror from the Deep had a Introviedo, no slideshow but if cinematics are important for you the game might feel a bit dry.
I was asking because I already have the HD version of TFTD, and wanted to get the CD-ROM version of the game also-not a big deal though.
What is the HD version of TFTD? Incidentally, I used openxcom to play TFTD and it was easy to replace the dos music with the CD music from the playstation version. And the same for UFO Defense. If there are any other assets from the CD version that's not in the dos version, possibly video clips, then I'd be surprised if those couldn't be easily imported as well.
