About Heat Death

This ancient galaxy is under attack by the mysterious "Apparitions". They are huge star-like monstrosities which threaten to consume the world. Your planet is controlled using cards which you collect while playing. Creativity and resourcefulness will be the keys to your victory!

Rewrite your cards!

Improve your deck even further by re-writing your cards! The game's unique crafting system is used to fuse cards into each other, allowing you to create insane synergies that feel like cheating. And yet, even with such powerful tools on your side, the enemy still puts up a fight!

Heat Death is in early access, but is almost ready for release - with 5 Planets, nearly 500 cards, and a crazy amount of depth and replayability.

  • The Human planet can swarm its opponents with drones, play defensively by buffing its allies, or stand on its own with versatile weapons and defenses.
  • The Radioactive planet focuses on fierce bursts of nuclear damage, and lays traps which detonate when opponents make their attack.
  • 'Storm' is a desert planet which can recover from almost any attack with its powerful heals and repairs, while steadily growing stronger with every passing turn.
  • 'Ablaze' is a volcanic planet, dishing out vast elemental damage while protecting itself in a veil of ash.
  • 'Sanguine' is a planet of witchcraft. A Sigils and blood moons forebode the end of its enemies.



The game world consists of procedurally generated maps of stars and clusters. Death is permanent – you start from scratch each play session, but you expand your knowledge and unlock higher tiers of difficulties. The powerful deckbuilding and card crafting in Heat Death allows you to explore new strategies with every new attempt. And if you still want more, then there are also cheats and challenges, to make the game even crazier.
