Single Player

Join the Steel Diver Submarine Corps and pilot your sub through a variety of challenging naval missions, each with three difficulty levels. Complete a mission within a tight time limit to earn an achievement medal – do you have what it takes to earn achievement medals in every mission on the highest difficulty?


Carefully steer your sub through floating rings and sink an enemy convoy while under attack from bombers, before advancing to even more dangerous missions exclusive to the Premium Version.


Internet Battle

Get ready for intense 4-vs-4 warfare! Take on opponents of your skill level, play just with friends* or go up against all-comers, working with your team-mates to win the day.

Use authentic Morse code to send messages to your team-mates and seek out your opponent with sonar, but watch out – using your sonar will alert the enemy to your presence, so use your cunning and stealth to avoid detection and win the day.

The last team standing is declared the winner. Can you help steer your team to victory?

Local Wireless Battle

Choose your side and do battle with up to seven friends in a range of underwater arenas. Computer-controlled subs will fill in for any missing players, but sinking them won’t count towards victory, so it’s a true test of skill.

As you progress through the single-player and multiplayer modes, you’ll unlock larger and more powerful vessels. Each has its own unique strengths and weaknesses, so find the sub that works for you and make it your own!

In the purchasable Premium Version, unlock and command up to 24* unique submarines across seven varied missions. Try the first two missions and two basic submarines for yourself in the Free Version!


Short-range attack subs

While these subs carry larger numbers of torpedoes that are quicker to reload, they do less damage than those on other vessels. Bombard your opponents with bursts of fire before they can retaliate!


Mid-range all-purpose subs

A good all-round submarine, possessing moderate torpedo strength and generally quick reload speeds, with average stats in most other areas. A good choice for commanders at the beginning of their naval careers.


Long-range support subs

These pack the most powerful torpedoes, but can suffer from long reload times and sluggish underwater speed. Use their superior firepower to take down your opponents before they close in.


Extra submarines

In both the Free Version and Premium Version, you can also purchase and download 15* extra vessels based on important historical submarines, including the German Type VII U-boat, British commerce raider HMS X1, Japanese Sen Toku I-400, United States Navy Gato Class fleet submarine, and the French Surcouf.


After finding a submarine that suits you, you can enhance its strengths or make up for its weaknesses by assigning crew members, each of whom has a different statistical or strategic benefit. You’ll need to rescue crew members before you can make use of their skills though, so consult the Crew screen for hints to their location before setting off!

You can also camouflage your sub, making it harder for your enemies to detect you. Additional camouflage options can be unlocked by completing multiplayer matches, so the more you play, the bigger your advantage can be. Choose a camouflage pattern and colour scheme to create your own truly unique vessel!

Lastly, the number on the side of your submarine has a special significance: it reflects your longest win streak, so the more consecutive victories you score, the larger the number becomes. Scope out other players’ win streaks when playing online to help you prioritise your targets, but don’t forget they might be doing the same!
