NLO 2: Dyavoly Bezdny

NLO 2 is a sequel to a unofficial remake of UFO: Enemy Unknown for ZX Spectrum. This time, the game deals with the franchise sequel called Terror From The Deep, where the alien threat moved from the skies into the depths of the oceans.

The game stayed pretty much the same in the basic ideas and the graphics - it's a tactical strategy with a global map mode & research. However, there are noticeable changes to the interface and the world map.

The most important change is that the ground battles became turn-based, as in Terror From The Deep. Air combat has also been changed. This time it's an arcade shooting sequence, where you need to hit the saucer that moves around the screen from a first person view.
