Our take on Heat Death

The bounce point arrives when a failed session resets progress to the beginning. Players who are comfortable rebuilding decks may continue, but those seeking persistent runs can hit the wall there, especially as card fusion and nearly 500 cards add further decisions.

What is Heat Death?

Heat Death is a single-player deckbuilding game set in a galaxy threatened by star-like Apparitions.

Cards control the player’s planet, and a crafting system lets players fuse cards to create new combinations and synergies. Five planets offer different approaches, including drones, defensive buffs, nuclear bursts, traps, healing, repairs, elemental damage, ash protection, witchcraft, and blood moons. Each session uses procedurally generated maps of stars and clusters, with permanent death sending players back to the start. Knowledge and higher difficulty tiers carry forward between attempts. The game is in early access and includes nearly 500 cards, along with cheats and challenges.
