Calculus of Rot

Calculus of Rot is a turn-based tactical survival roguelite set in a zombie-infested wasteland where every decision can mean the difference between life and death. Exploring one tile at a time beneath a dense fog of war, you’ll uncover abandoned locations, search for useful supplies, and carefully plan your route through maps filled with mutants and dangerous infected. Every encounter consumes valuable health and resources, making it just as important to know when to avoid a fight as when to stand your ground.

As you venture deeper into the wasteland, increasingly powerful abominations emerge, forcing you to constantly reassess the risks ahead. Studying enemy strength, managing your limited actions, and choosing the safest path through each area become essential parts of survival as every map evolves into its own tactical puzzle. With procedurally unfolding exploration, strategic resource management, and challenging turn-based combat, every expedition offers a fresh test of planning and survival.
