X-COM: Terror from the Deep

The Good
Well, the AI has been improved (to the point of madness), the game engine is a little faster and the UFOpedia has been given a boost.

The Bad
Game is simply TOO DAMN DIFFICULT, the graphics are less appealing than the first and the game has a much less claustrophobic, stretching atmosphere.

The Bottom Line
A lot less fun than the first, but still makes a good game.
