Description



Cobalt Core is a sci-fi roguelike deckbuilder with a unique single-axis combat system that will throw you for a loop. Many loops!



Give orders to your crew by playing cards: Will you raise shields to protect your ship, dodge incoming missiles and cannon fire to avoid damage outright, or strike preemptively to disable your enemy’s weapons? Outmaneuver your foes to stay just ahead of impending calamity, and reach the Cobalt Core!



  • Fresh new spin on tactics – dodge attacks and target weak points in this unique single-axis take on tactics combat. Outwit the enemy in a high stakes game of cat and mouse!
  • Customize your deck – hundreds of cards and split upgrade paths means no two runs will be the same. Find that perfect combo that brings your deck from powerful to overpowered.
  • Get to know your crew – each character comes with a completely unique playstyle and their own personal story. Bring 3 along, mix and match their decks, and see how these little goobers get along with each other.
  • Tons of replayability – hundreds of different character+ship combinations before you even hit “start run”. Crank up the difficulty and really test your skills!
  • Daily Challenges – Keep runs fresh with all sorts of modifiers. Can you win with just 1 character, or with your ship scrambling itself every fight? Play at your own pace, or get competitive on the leaderboards!
  • Get in the groove – featuring 90+ minutes of catchy and electrifying original music by Minecraft composer Aaron Cherof!
  • Forward momentum – untangle a narrative and unlock more playstyles as you go. Is there any escape from this time loop?

Cobalt Core is a real innovation and iteration on the roguelite deckbuilder genre. I’ll do a lot of comparison between this game and Slay the Spire (StS), which I think most people interested in this game will have

overall solid, though it wears its influences too closely for me to appreciate its differences. it doesn't help that this game is comparatively bite-sized, which forces the player to rely on a small set of optimal

A pretty simple and fun roguelike! Movement is good, cards are pretty balanced (except Parry, which is completely OP), and the mechanics guide you to try out every character. I'd say it's worth the price for the mileage

Game breaking bugs galore since the update. Super obvious stuff. I've restarted so may times and the bugs remain. So obvious I'm not even going to list them. Play your own game devs.

A very cute lil deck builder game that was highly enjoyable. It felt a little long in the tooth story wise, having to effectively beat the game 24 times. But it was very well worth doing so in the end! The final push

Solid game. A colorful strategy game with a simple quippy story. The game leans shorter. Once I knew what I was doing, my casual runs tended to be ~30 minutes. The Normal difficulty is well-balanced. While this game has
