Indie developer Lyra Studio is thrilled to announce that FrostBound, the roguelike deck-building tower defense game set in a relentless frozen world, will launch for PC via Steam on November 27th, 2025. Players can add FrostBound to their Steam Wishlist now.
FrostBound takes inspiration from Game of Thrones, channelling its brutal battles, human conflicts, and the desperate fight against an endless winter. Echoing the firelit stands beyond the Wall, the game turns those themes into strategic survival, where fragile alliances, unexpected heroes, and unity are the only way to endure the cold.
Endless Strategy in a World of Ice
FrostBound combines deep deck-building with tactical defense and roguelike replayability. With nine escalating difficulty levels, every run tests your adaptability - tougher enemies, tighter resources, and new events like Fortifications and Beacons that reshape the battlefield and your strategy.
Players can unlock and customize their deck from over 500 cards across four factions and five categories - Attack, Defense, Skill, Structure, and Elite - each offering new tactical options. Nurture powerful Elite heroes, exploit risky Curse cards, and experiment with endless combinations to craft your own path to survival.
Built on pillars of adaptive difficulty, replayable challenges, and achievement-driven progression, FrostBound ensures no two battles ever play the same. Whether you’re optimizing complex synergies, testing new deck archetypes, or pushing for survival at the hardest tier, every victory feels earned in this beautifully brutal frozen world.

Lead the construction of your fortress, marshal resources, and withstand waves of twisted enemies in a world where the frost never ends. With a massive 500+ card pool, countless building upgrades, and heroes with unique abilities, you’ll craft the ultimate defense and turn the tide against the unyielding cold.
Plan each turn carefully, decide when to attack or reposition, and balance the harsh conditions that force units to retreat. Only your strongest warriors and fortifications will endure the relentless frost.
FrostBound has already turned heads across the industry. The game was nominated for the 2025 indiePlay China Independent Game Awards’ “Best Design Award” and named a finalist at the 17th Golden Dolphin Awards during the Xiamen International Animation Festival, early recognition that highlights its inventive design, striking art direction, and the passion driving Lyra Studio’s vision.
