About This Game

is a chaotic 2D bullet-heaven action roguelite where biology stops being a textbook chapter and turns into a full-scale survival arena.

Play as Eggnes, guardian of the egg cell, and stop absurdly massive waves of sperm before even one of them reaches its destination. Move, dodge, dash through the crowd, collect XP and choose cards capable of completely transforming your run.

Eggnes may not have to defend the organism alone forever. Other forces are operating somewhere within, but their identities, combat methods and levels of emotional stability remain classified by the laboratory.

Combine acidic auras, antibodies, ricochets, spears, shields, explosions, hormonal zones of chaos and Medically Mythic synergies. Activate antibody towers scattered across each map, develop their modules and use different defensive doctrines. A good build can turn the organism into a biological fortress. A bad one can still look impressive for several seconds.

Fight through a series of biological environments, each introducing its own layout, hazards, tower network, special enemies and final confrontation. Watch out for acid pools, contractions, mucus tides and enemies that explode, steal XP, block projectiles or attempt to disable your defenses.

When regular runs are no longer enough, face mutations that change the rules of the game or enter Boss Rush and discover how many biological disasters you can defeat without a moment to recover.

During combat, you will also receive mini-quests and educational questions. A correct answer strengthens your guardian and one of your towers. A wrong answer makes the organism charge interest on your confidence.

After each run, spend research points on permanent laboratory upgrades. Expand your card collection, complete the bestiary, recover strange Chronicles, earn achievements and discover secrets that the research department definitely should not have left unattended.
