Build your deck, re-write your cards, and join in epic space battles! Heat Death is a single-player deckbuilder which takes card customization and power scaling to the extreme, as you battle against sentient stars and black holes.
The core gameplay loop revolves around building and customizing a deck of cards to tackle increasingly challenging battles. A standout feature is the deep card customization and crafting system. Players can "rewrite" their cards, fusing them together to create powerful synergies and combos. This allows for a high degree of deck experimentation, as players continuously work to break the game by building overpowered card combinations.
The game currently features four playable planetary factions, each with their own unique mechanics and strategies. For example, the Human faction focuses on swarming the enemy with satellites and drones, while the Radioactive planet utilizes a resource called "Radioactivity" to power devastating attacks. The Storm planet specializes in healing and self-buffing, and the Ablaze planet excels at inflicting the "Burning" debuff. This diversity of playstyles encourages multiple playthroughs as players explore the different approaches to victory.
The game features a difficulty scaling system, allowing players to incrementally increase the challenge level up to 10, unlocking new cards and mechanics along the way. This provides a sense of progression and mastery, as players gradually overcome higher difficulty levels through strategic deckbuilding and card crafting.
The combination of card crafting, planetary abilities, and difficulty scaling leads to highly emergent and unpredictable gameplay. Players can create wildly powerful card combinations, unleashing devastating attacks or gamebreaking defensive strategies. The ability to "break" the game through clever deckbuilding and synergy exploitation is a key source of enjoyment for many players.
