Grey Seas: Submarines

Take command of legendary World War II submarines and stalk enemy warships beneath hostile seas.

In GREY SEAS: SUBMARINES, you command historically inspired submarines in tense naval missions where patience, positioning, and timing decide whether you become the hunter — or the hunted. Track enemy ships, approach convoys undetected, calculate the perfect firing solution, and launch your torpedoes before slipping silently back into the depths.

Choose from famous submarines inspired by vessels that fought across the Atlantic, Pacific, Mediterranean, North Sea, and beyond. Each submarine has unique speed, diving depth, maneuverability, torpedo capacity, reload time, and underwater performance, along with a distinctive silhouette based on its real-world design.

Each campaign takes you through waters connected to the history of your selected submarine. Read short historical briefings, follow routes across campaign maps, and complete missions in sequence to unlock new operations.

Patience matters. Torpedoes are limited, and every shot counts. Study the enemy’s course, estimate the perfect intercept point, and wait for the right moment to strike.

But once your position is revealed, the battle changes.

Enemy destroyers will hunt you with sonar and depth charges. Dive, maneuver, reduce your speed, and disappear before they can locate you. Sometimes the best attack is the one the enemy never sees coming.

All submarines can be viewed and selected freely. The free version includes a selection of missions, while a single full-version purchase unlocks additional campaign content.

The enemy is above the surface.

Dive deep. Hunt silently. Strike without warning.
