Sinking Steel

The hit is the last sentence. The story is the calculation.

Measure range, speed, bearing, and angle on bow to earn the perfect torpedo shot while managing depth, speed, stealth, and exposure.

Sinking Steel is a compact submarine simulation built around the slow pressure of manual torpedo targeting. Players command a diesel-electric submarine, stalk surface contacts, raise the periscope, identify silhouettes, estimate range and speed, judge angle on bow, and feed the torpedo data computer with the best solution they can build.

The game focuses on the tension before the shot: staying hidden, managing depth, controlling speed, avoiding detection, and deciding when the firing window is good enough. A perfect hit should feel earned through observation, patience, and calculation — not automatic lock-on.
