Cosmic Crossover: Roguelike Basketball key art, showing a lineup of alien and mutant basketball players facing off on a neon court in deep space

Draft aliens. Stack relics. Win the galaxy.

A roguelike basketball sim. Draft five misfit ballers from across the galaxy, then coach them through three escalating tournaments while the game simulates every possession.

What you're getting into

Draft your five

Wrestlers who live on the glass. Oozes that never get tired. Sharpshooters from dying stars. Every character has authored abilities that grow as they level, and every race and playstyle feeds team-wide synergies. No two drafts play the same.

Break it with cosmic relics

Beat bosses and scour the galaxy for run-altering relics and gear. Build around foul-baiting, seven-seconds pace, defense that scores, or pure hero-ball. Relics stack into engines, and engines win championships.

Coach the moments that matter

Games simulate live with full play-by-play, but you're never a spectator. Pause at quarter breaks to adjust matchups, react to in-game events, and outfox rival coaches in blind tactical battles.

Survive the run

Your coach has health, and every point you lose costs some of it. Manage your gear at tip-off, gamble at scout events, spend big at the Galactic Exchange, and take down three tournaments of escalating alien squads.
