FrostBound frames its strategy around humanity’s survival in a world locked in endless winter. This roguelike deck-building game combines base construction and resource planning with defense against enemy waves. Its premise gives each battle a larger stake: protect the last spark of civilization while facing a world whose secrets remain unexplained.
The distinctive format is turn-based card tower defense. Players choose to attack or position troops on each turn, but the harsh cold makes units retreat after a single turn. That rule puts weight on the structures and warriors able to remain in place. More than 500 cards, four factions with distinct playstyles, and combinations between factions support varied approaches to building a defense; an elite-card system also allows growth within each battle.
The game describes ten starting heroes, each with a signature skill, alongside more than 100 upgradable buildings that can reshape the battlefield. Its enemies include more than 70 foes, and the listed format is single-player.
