Cooperative and head-to-head multiplayer modes allow controllable submarine, surface, and air platforms to battle it out in the definitive naval combat experience. Players can command a platform on their own in multiplayer, or collaborate with multiple players in "Multi-station Mode" as they each operate individual crew-stations and strive to work together as a team on the SAME platform. By assigning certain crew stations to be manned by the "virtual crewmen" the player can hand off various functions for the simulation to manage.

This allows the player to tailor the game's difficulty level to their liking and the precise level of involvement and micro management that they wish. The player could choose to monitor every single crew station himself or choose to just command the platform and to let the A.I. do the rest. Autocrew control is dynamic so the player can enable or disable this feature for every crew station modeled in the game.

Merchant ships are broadly classified on the basis of their sizes and areas of operation. The classification of the ship is decided right at the design stage on the basis of route of operation and purpose of the ship.

The ship’s dimensions play an important part in determining the areas of operation of any type of merchant vessel. A variety of parameters such as draft, beam, length overall, gross tonnage, dead weight tonnage etc. are taken into consideration while designing and constructing a merchant ship. For e.g. for designing a ship that would be able to pass through the Suez Canal, the dimensions of the ship would be decided in such a way that the ship is able to smoothly transit through the narrowest and shallowest areas of the canal, in both fully loading and unloading conditions.

Ship sizes chiefly vary on their load carrying capacitance, just as their variance alters on the constructional capacitance of the various ports and harbors.

It is difficult and expensive to do vessel-specific training well - which is probably why it is under specified, and in many cases poorly implemented - often via job shadowing.
