In its simplest form, Enemy Waters is a cat and mouse game between submarines and ships. The player will control a naval fleet comprising of ships and submarines, using which he has to outsmart and outflank his enemy's fleet.
Setup ambushes for Convoys using WW2 era Wolf-pack tactics, or engage silent running and sneak past enemy patrols to get to a position of advantage, before breaking stealth and launching a salvo of torpedoes, or feign an attack and lure enemy vessels into a constricted area where you can concentrate your fire . These kinds of advanced naval maneuvering is possible in Enemy Waters.
The Game features 10 submarines and 9 anti-submarines frigates (ships) ranging across different nations and different time periods with realistic physics.
