Extraneum is a fast‑paced sci‑fi roguelite that fuses twin‑stick shooting with deck‑building strategy. You step into the boots of a lone operator on a hostile, ever‑shifting space station, blasting through procedurally generated corridors and arenas teeming with lethal machines. Along the way, you collect and merge “cards” that represent weapons, upgrades, drones and defensive systems—crafting a unique loadout on every run.
