Our take on Cubic Cosmos

Rather than treating deck building as a sequence of isolated card exchanges, the game combines it with tower defense and pawn management. Its runs also emphasize chained turns, shared pawn setups, and battlefield-wide effects alongside standard roguelike progression.

What is Cubic Cosmos?

Cubic Cosmos combines roguelike deck building with tower defense.

Cards and Relics shape a deck, while pawns form an army whose attributes, abilities, and combinations determine each battle. Runs include random events, boss encounters, daily challenges, and more than 10 difficulty levels. Clearing runs unlocks 12 heroes across three classes, each with distinct abilities. The card pool contains more than 240 cards, and over 50 equippable Relics add further effects. Mastery Mode tests completed decks in a high-pressure setting. Players can also share pawns through Doll Codes, which support 11 Doll types, and share battle moments using generated Battle Codes.
