Cosmic Mart was the most prosperous supermarket in the sector, until an alien infestation turned its aisles into a flesh-eating nightmare. You are an independent extreme-cleaning contractor. Your mission: ascend through the bowels of the ship, wipe out the infection room by room, and reach the sixth floor to collect your paycheck. Brace yourself for a frantic action roguelike where the environment is just as dangerous as the plague. Every level is made of lethal, procedurally generated rooms. Here, survival depends on your ability to dodge bullets and enemies, and build destructive item combinations. Shoot, die, swap your mercenary, and try again.
