X-COM: Terror From the Deep

The game expansion X-COM: Terror From the Deep follows on from the successful X-COM: UFO Defense. The war against the hostile alien race moves to a new front—the dark depths of the oceans, where an army of alien creatures is awakening. This turn-based strategy game for PC will test your tactical skills in an underwater environment. The base game X-COM is required for activation and play.

Underwater Combat and New Technologies

The underwater environment brings new tactical challenges. The game includes a system for creating underwater maps with rich topographical details that influence your strategy. You will have a wide range of underwater military technologies to combat new threats. Tactical maps are now multi-level, including both the seabed itself and the interiors of buildings. An expanded encyclopaedia will provide you with information about the new inhabitants of the deep and their equipment.
