Game Overview
A starship trapped in a collapsing sci-fi time loop turns every encounter into a tense lateral duel of positioning, timing, and card-driven improvisation. Cobalt Core is a roguelike deckbuilder with the satisfying run-building appeal of Slay the Spire, but its battles play out on a single horizontal lane where ships weave around incoming fire rather than simply trading damage. The mood stays bright and witty despite the stakes, thanks to a charming crew of oddball pilots and a story that gradually reveals why the same disastrous journey keeps repeating.
Each turn, you spend cards drawn from the decks of your three chosen crew members to fire weapons, reinforce shields, move the ship, disrupt systems, or prepare delayed effects. Movement is the key twist: missiles, beams, and cannon shots occupy visible spaces on the combat line, so a well-timed dodge can negate a devastating attack without spending defense at all. Enemy weak points and weapon systems create priority targets, rewarding players who can read upcoming threats and decide whether offense, protection, or positioning matters most. Victories grant cards, upgrades, relic-like equipment, and route choices, while branching upgrades and deck combinations allow a focused strategy to become wonderfully excessive.
Its combat feels more spatial than most deckbuilders, turning every hand into a compact tactical puzzle instead of a routine damage calculation. Crew members bring distinct card pools and personalities, and pairing them with different ships dramatically changes how a run handles mobility, energy, defenses, and weapon pressure. Persistent unlocks, escalating challenge levels, alternate builds, and the unfolding loop narrative give failed attempts a sense of momentum rather than wasted time. Anyone who enjoys roguelike card games but wants more active battlefield control should find Cobalt Core approachable at first and remarkably deep once enemy patterns, crew synergies, and movement tricks start clicking.

Check that extraction completed and your PC meets the system requirements. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
