Using the machine gun and torpedoes of the submarine the Gunner defends the submarine from foes, human or otherwise, destroys debris, and provides illumination with flares.
- Aim at a target: Mouse
- Load the torpedo tube mechanism: 1 2 3 4 5 depending on the torpedo to be loaded
- Launch right torpedo: Right mouse button
- Launch left torpedo: Left mouse button
- Fire machine gun: Left mouse button
- The machine gun has unlimited ammunition, using it liberally is a good way to save precious torpedoes.
- The submarine has a limited number of torpedoes, so it is best to coordinate with the Pilot to fire perfect shots at enemies.
- Torpedoes have an explosion radius, so be careful firing them at nearby objects/enemies--they will damage your submarine if you are too close!
- Utilize the machine gun on weaker faster moving enemies, as torpedoes travel through the water slowly.
