About this game
What this game is, in the developer's words
Fight your way through zombie-infested wastelands in a turn-based tactical survival game. Reveal the map tile by tile, manage your health, choose your battles wisely, and survive against increasingly dangerous mutants lurking in the darkness.
The world is dead. Mutants roam the ruins, and every step forward could be your last.
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.
