Shindo 40 -FATHOMS FORCE-

Released by Comptiq in 1984, "FATHOMS FORCE" is a simulation game set in the North Atlantic during the final stages of World War II. Players take on the role of a U-boat captain under Hitler’s direct orders, tasked with sinking enemy fleets with a limited supply of eighteen torpedoes. Developed in BASIC, this title represents an early experimentation with simulation mechanics on home computers and serves as a rare example of capturing historical tension within strictly limited technical resources.

In the North Atlantic during the final days of World War II, the German military faces a deteriorating situation and deploys a cutting-edge U-boat as a last-resort gamble to reverse the tide of war. As captain, you receive special orders from Hitler and submerge into waters teeming with enemy fleets. Faced with only eighteen torpedoes and immense pressure, you must engage in a lonely battle to sink the enemy and alter the course of the war.
