Embark on a thrilling journey as the Cardstronaut in this 2.5D roguelike deck-building adventure! Set on a desolate alien planet, you play as a space engineer who returns to find your massive mining base overrun by hostile aliens. With communications down and your colleagues in danger, it’s up to you to fight through the base, room by room, using your engineering skills and a unique deck of powerful cards. Balance the gas levels of ceiling-mounted flamethrowers to burn your enemies without overflowing the gas and hurting yourself. Siphon precious alienium from the aliens to turn the tide of battle. As you progress, choose from a variety of cards and trinkets that synergize in powerful ways, allowing you to craft unstoppable strategies—until the next wave of enemies challenge your newfound power. Explore procedurally generated maps filled with events, vending machines, and hidden surprises. Will you master the alienium and rescue your crew, or will the void consume you?
