ABOUT THE GAME

Two sailors,
Protect one submarine.

``My Rusty Submarine'' is a cooperative survival game by Sørb and DrLudwig3. Travel around the interior of the submarine, interacting with power, steering, electrical, and submersion equipment to address the next problem before it shuts down.

01

Move the sailor with two sets of keys

The first person uses WASD, Space, and E, and the second person uses arrow keys, J, and I to move, jump, and operate. You can operate two sailors using the same keyboard.

02

Keep navigation with coal and rudder

Transport the fuel from the coal machine to run the engine and align the compass direction and rudder. Switch roles before velocity reaches 0.

03

Deal with water leaks and disconnections in order

Repair leaks and pump out accumulated water. Broken cables must be repaired with the electricity turned off, and multiple equipment will also be shut down during a power outage.
