What is Cobalt Core?

This single-player, turn-based deckbuilder follows a spaceship crew caught in a time loop. For each run, choose three crew members and combine their decks, then play cards to move your ship along a single axis, raise shields, and disable enemy weapons. You uncover the crew’s stories and unlock more playstyles as you progress.

For you if...

  • +you enjoy combining character decks and experimenting with card synergies
  • +you like a lighter tone in science-fiction games

Not for you if...

  • −you prefer a continuous campaign instead of repeated runs
  • −you want reflex-driven action rather than deliberate card choices

What players say

96% of 4,172 reviews are positive · 90% of 30 in the last 30 days

Players praise the ship-positioning combat, soundtrack, and crew interactions. A recurring complaint is limited enemy and encounter variety, with some players also finding the card drafting shallow and runs repetitive.
