A sandbox game by Unknown Worlds that combines elements of action-adventure productions and RPGs. As the game’s universe draws inspiration from such novels as Twenty Thousand Leagues Under the Sea, at the bottom of the ocean you can find bizarre sea monsters, as well as remnants of futuristic buildings and ships. The player assumes the role of a captain of an advanced submarine, and explores the depths of the ocean. The game’s characteristic feature is the ability to design vessels and determine such things as performance, layout, on-board mechanisms, and materials used for the construction. You begin with rather primitive ships, but as you progress you will be able to construct more advanced vessels, and explore previously unavailable parts of the ocean. While playing, you can freely walk around your ship, and even go outside to explore the marine world on your own.

A science fiction horror adventure game created by Frictional Games, Swedish studio known for such titles as Amnesia: The Dark Descent and the Penumbra series. The game is set in a top-secret research center PATHOS-2, where a series of failed experiments resulted in human-like machines killing off most of the staff and taking over the facility. You play as one of the survivors, who has to safely evade the hostile, machine infested environment. Gameplay is presented in first-person perspective and focuses on exploration of the facility and avoiding direct contact with the enemies. Just as in the other works from this developer, instead of dynamic action sequences, the game emphasizes the thick, dark atmosphere and a persistent feeling of vulnerability.

Mechanics of UBOOT combine the features of Silent Hunter and Fallout Shelter and the main task of the player is to take care of the crew. One must consider physical and emotional limitations of his subordinates, assign functions to them etc. Each crew member has his own personality and different weaknesses which can be revealed if the captain fails to keep balance between discipline and despotism. As the game progresses one can upgrade the submarine, but our opponents obtain new technologies, such as radar, as well. UBOOT is a three-dimensional game but most of the time the action is shown on a cross-section of the submarine.

An arcade submarine simulator with crew management elements. The game was developed by an independent team known as Arachnid Games. The story of Diluvion takes place in the distant future, where an apocalyptic flood has forced humanity to colonize the ocean depths. The gameplay is focused around exploration of a marine world of a considerable size, completing various tasks, and combat with encountered opponents. Our travels often require the use of a sonar, which helps in navigating dark areas, as well as ranged weapons in the form of torpedoes or even cannons. We’ve also received access to a crew management module – throughout our journeys, the individual crew members gather experience, acquiring new skills over time. For example, an experienced coxswain offers better maneuverability, while a talented cannoneer is much more accurate.

Depth was designed with multiplayer experience in mind. In the game there are two competing teams – scuba divers, and sharks that try to hunt them down. The game is a debut by a studio originating from the modding community – Digital Confectioners. The action takes place exclusively underwater, and the two teams have completely different goals to accomplish. The task of the divers is to locate a valuable object and bring it to the surface. The other group, playing as sharks, needs to prevent the first team from doing so, which, most of the times, boils down to eating them. The gameplay is pretty realistic – the divers’ movements are limited by all the physics of submerged bodies, while the sharks make use of their animal instinct without hesitation. High quality graphics are provided by the Unreal Engine 3.

Subsiege is an original blend of a real-time strategy and a MOBA game developed by the German studio Icebird. The game takes place in the second part of the 21st century, when almost all of the Earth's natural resources are depleted. The depths of seas are the last place where they can be found. This leads to a full-scale underwater war for those exact resources. Before we start, we have to chose a couple of ships from the available ones. We will be able to use and construct only them during the RTS matches. As we play, we will have to build special structures that will gather the resources and will have to lead a group of combat units to battle. Each ship has a limited amount of oxygen, so we will have to gather as much resources as possible before our crew members face asphyxiation. We can increase our oxygen supplies by gathering oxygen tanks from destroyed enemy ships. The game offers a multiplayer mode (both co-op and competitive) along with a single player campaign. The game's PvP world has a permanent nature and constantly changes as a result of players' actions.
