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?

Probably one of the best FTL like games that's come out. It introduces some unique mechanics that really add a lot to the genre. It also is super adorable visually. Definitely one of the best deck builders out there.

One of the more unique deckbuilders I've played. I love the art style and wry humor built into the surprisingly deep narrative. Very fun game mechanics and has lots of replayability. Highly recommend to anyone looking

A solid fun roguelite deckbuilder with great music and fun character/NPC interaction on top. The main actions are "move (now/later), attack, shield, deploy midrow object (e.g. missiles, drones)". And you use those blow

So, just beat the basic stuff to get the ending. It made me tear up. Would recommend. I'm not sure who is Best Girl, Riggs or Books. Both had their moments in that sequence. So, actual review. The game is actually

I like roguelikes, but I also live under a rock, and didn't hear about this one until the year of 2026- somehow. You'll hear others say FTL + Slay the Spire, and that bastardization is mostly correct. There is a bit of
