Summary
Essentially X-Com: Harder, With Water
The Good
Everything to like about "X-Com" is to like about "Terror from the Deep." They're more or less the same game.
The Bad
X-Com was unfairly hard; Terror from the Deep is ludicrously hard. Even at the easiest difficulty level, with lots of experience and employing solid tactics, your men always have a better-than-even chance of getting run over like circus midgets at a steamroller convention. Without gave saves, getting a soldier through half a dozen missions is impossible.
The under-the-water motif never really made sense to me, but to each his own. The game does seem to be a giant continuity error, though; if it's set 40 years after the original X-Com, why has human technology gone backwards?
The Bottom Line
Basically just a facelift to X-Com, but too hard to play. Get X-Com, not the sequel.
