Infernal Machine: Dawn of Submarine Warfare

Infernal Machine: Dawn of Submarine Warfare is a solitaire board game that lets you design, build, and deploy an experimental Civil War submarine in a high-risk contest of engineering, secrecy, and attack planning.

Set in mid-19th century America during the Civil War, you take the role of an inventor and entrepreneur trying to turn a fragile concept into a working Fishboat. You recruit investors and crew, manage costs and construction, choose your submarine’s capabilities, and respond to shifting wartime conditions that can disrupt even the best-laid plans. The game can be played as historical scenarios or as a larger campaign in which you guide your project from early development to dangerous missions against the enemy.

Once your boat is ready, you assign crew positions, navigate difficult waterways, and try to survive the approach long enough to make your attack count. Play has a detailed, decision-heavy feel built around risk management, crew assignments, mechanical failures, and tense tactical choices at the moment of contact. A scenario takes about two hours to play, while a campaign unfolds across several gaming sessions. Available now at Boarding School Games—Launch your secret weapon.
