Explore dark, infected zones hidden beneath the fog of war. Reveal new paths, discover useful items, and carefully decide which enemies to confront. Every encounter costs resources, and every mistake brings you closer to death.
Study enemy strength, plan your route, and use your limited health and attacks wisely. Some monsters are worth the risk. Others should be avoided at all costs.
As you progress, stronger abominations begin to appear, turning each map into a deadly tactical puzzle where survival depends on smart decisions rather than luck.
