- Goal
- Share coal replenishment, steering, water leak repair, disconnection repair, and drainage to extend the submarine's cruising range without reducing its speed to 0.
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.
WARNING AT ZERO
When the fuel runs out,
The speed will soon fall into the warning range.
The engine will stop unless you replenish the coal, and if the speed reaches 0, the game is over. Move the sailor to the necessary equipment while watching the distance at the top left of the screen and the status display in the center.

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.
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.
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.
