"One-axis ship combat that clicks, enemies that don't keep up"
About
Cobalt Core is a sci-fi roguelike deckbuilder where every fight plays out on a single horizontal line. Your ship and the enemy sit on a one-dimensional track, and your cards move you left or right to dodge incoming missiles, line up cannons, and drop drones or mines between you. You pick a crew of three from eight characters, each bringing their own cards and abilities, and run through a branching sequence of fights toward a boss. Card synergies, ship choice, and positioning drive each run. The story unlocks piece by piece across multiple playthroughs, framed around a crew untangling a time loop.
Verdict
The one-axis combat is the trick that makes Cobalt Core worth your attention: positioning matters as much as your draw, and dodging a missile by shuffling one tile feels earned. The crew synergies open up once you start mixing three characters whose cards talk to each other, and the writing is genuinely funny rather than wallpaper. The catch is that the content runs thin. Standard difficulty rarely threatens, the enemy and event pool repeats fast, and once you've internalised the strong builds the runs stop surprising you. At under eight euros it's an easy recommendation, just don't expect the bottomless climb of its deeper cousins.
