Battle Flow

Move into the enemy territory

Move your submarine to a place where you think the enemy may be lurking. Only submarines can enter enemy territory.

Close in on the enemy

When you get close to enemy ships, you can tell where they're likely to be hiding, but you won't know their exact location.

Enemy ships may be hiding in these spaces.

Use your sonar

Discover the location of enemy ships by using sonar. Careful—when you do, you'll give away your own location to the enemy.

Attack enemy ships

Once you've found them, attack! Submarines can attack from periscope mode. Enemy escort ships can also attack you with depth charges.

Read your Foe's Movements

Since enemy movement can't be seen, you must predict your enemy's location and choose when to use sonar. If all goes well, you can close in on a transport ship undetected. If you've guessed wrong, you may be attacked.
