AquaNox 2: Revelation

It is the 27th century, and humanity has fled the surface of the Earth, plagued by radioactivity, into the depths of the ocean. William Drake is the last offspring of an old aristocratic family. After the death of his grandmother, the young man sails off on a freighter belonging to Drake Enterprises. Soon, a group of mercenaries attack his vessel and take control of it. The attackers spare William's life, but he has no other choice but to link his fate to theirs from that moment on.

Like its predecessor, AquaNox 2: Revelation is a hybrid of submarine simulation and first-person shooter. Four different gunships can be controlled and upgraded by the player throughout the course of the game. The vessels have different characteristics and often have to be chosen for particular missions, e.g. one that requires stealth or heavy plating to withstand attacks. Torpedoes and energy-based weapons can be used to combat the foes. The ship's controls can be switched between the FPS mode and the Simulation mode, in which the submarine is controlled more realistically.
