• free redistribution of commander skill points for the commanders that came with the submarines
• no upgrades, camouflages, signals, researchable modules

Depths

0-6 m under the surface (Surface Level)

Pros:

• faster
• can capture/block areas
• battery is recharged regardless of speed
• fast battery recharge
• higher spotting range
• torpedoes can be used like with a normal ship
• cannot be hit by depth charges
• your Radio Location skill is active (if you have it)

Cons:

• can be hit with shells, ship- and airborne torpedoes, aerial bombs, and rockets
• highest detectability range
• Emitting sonar pings while on the surface increases the submarine's detectability more significantly than while underwater.
• can't detect enemy submarines that are 30 m or more under the surface, even if distance < 2 km (but is detected by them)
• you can be located by enemy ships/submarines which are at the surface and have the Radio Location skill

6-80 m under the surface (Submerged)

Pros:

• detectability reduced
• cannot be hit with shells, ship- and airborne torpedoes, aerial bombs, and rockets
• Emitting sonar pings increases the detectability less.
• you cannot be located by enemy ships/submarines with the Radio Location skill

Cons:

• can be hit by depth charges
• battery charge is depleted when moving underwater at speeds higher than 1/4, and when reversing.
• battery recharges only when speed is between 0 and 1/4
• slow battery recharge
• cannot capture/block areas
• speed drops significantly
• spotting range decreases to the value of torpedo range.
• enemies that are detected by your team but are beyond your spotting range are not shown on your minimap
• can't detect aircraft
• no aircraft (neither enemy nor allied) are shown on your minimap
• your Radio Location skill is not active

6-30 m under the surface (Detection Depth)

• detectability range reduced but > 0 km

Cons:

• the Hydrophones on destroyers allow them to determine the approximate location of the submarine.

30-80 m under the surface

Pros:

• detectability range is 0 km
• can be detected only by ships with Hydroacoustic Search, and by submerged submarines if distance < 2 km
• not detected by ships/submarines at surface even if distance < 2 km (but detects them)

30-50 m under the surface (Operating Depth)

Cons:

• the Hydrophones on destroyers allow them to determine the approximate location of the submarine.

50-80 m under the surface (Maximum Depth)

• only reachable while Maximum Depth consumable is active

Additional pros:

• invisible to enemy hydrophones
• reduced damage from depth charge explosions

Submarine Controls

• The W, A, S, and D keys control horizontal movement.
• Press F to ascend.
• Press C to dive.
• Ctrl+F and Ctrl+C lock the horizontal rudders to either ascend or dive.
• 1—sonar pings.
• 2—torpedoes.
• Press 1 again to choose between two sonar ping options: wide and slow, or narrow and fast.

Sonar Pings

• wide and slow, or narrow and fast
• needs enough battery charge
• reduces battery charge
• temporarily increases detectability range (for 20 seconds if detected)

Battery Charge

• needed for sonar pings
• reduced by sonar pings
• fast recharge at surface level
• slow recharge when submerged and speed between 0 and 1/4
• reduced when submerged and speed higher than 1/4 (or reversing)

Depth Charges

• on all destroyers
• on cruisers Dallas, Leander, Budyonny, Perth
• damage submerged submarines (except allies)
• do not damage submarines/ships at the surface
• can cause fires and floodings
• reduced damage when submarine is 50 m or more under the surface (using Max. Depth consumable)

Hydrophone

• on most destroyers (not on Västerås)
• allows them to determine the approximate location of the submarine, except when submarine is 50 m or more under the surface (using Max. Depth consumable)
• Range: 6 km

Hydroacoustic Search

The Hydroacoustic Search consumable can detect a submarine at any depth.

Smoke

• Submarine at detection depth is not detected by enemies at surface that are in smoke even if distance < 2 km (but detects them).

Radio Location Skill

• does not locate submerged enemy submarines
• on submarine: only active when at surface level

Teams

• 12 vs. 12.
• Teams are filled with bots if there are not enough players.
• It seems that there are never more than 3 submarines per team.

Maps

• Neighbors
• Trident

Battle Modes

• Standard
• Domination with 4 areas
