Loop Hero is an auto-battler roguelike where you don't directly control your hero's movement or combat. Instead, you influence the world around them by placing cards on the looping path and adjacent tiles. Your hero automatically walks the loop, fighting monsters, gathering resources, and getting stronger. The goal is to restore the world from a mysterious void, one loop at a time.
The game combines elements of deck-building, resource management, and strategic tile placement. Each expedition is a fresh start, but progress in your camp carries over, unlocking new cards, classes, and structures that enhance future runs.
