Infernal Machine: Dawn of Submarine Warfare

Infernal Machine: Dawn of Submarine Warfare is a dedicated solitaire game that puts you in the role of an early submarine pioneer during the American Civil War.

This is not a traditional naval wargame. Instead of commanding fleets, you design, fund, and operate a fragile experimental “fishboat” in an era where underwater warfare was barely understood and often dangerously unreliable. Every decision—from engine type to weapon choice—shapes how your missions unfold.

The game combines a strategic layer, where you manage resources and plan operations, with a tactical layer focused on the actual attack runs. Once submerged, the tension shifts inward: crew fatigue, panic, oxygen supply, and mechanical failure become just as threatening as the enemy blockade.

What sets Infernal Machine apart is its focus on the machine itself. You are constantly balancing risk and survival, trying to push experimental technology just far enough to succeed without it failing catastrophically. It creates a tight, narrative-driven experience where every mission feels personal and hard-earned.

This is a strong pick for solo players who enjoy immersive, systems-driven gameplay with a historical edge—especially if you like games where managing the situation is just as important as achieving the objective.

Contents include: game boards, cards, tokens, and player aids for both mission planning and tactical submarine operations.
