Our take on Petit Petit Petit

Rather than centering on a conventional hero, the game puts immune cells and medical nanomachines in control of the fight. Its progression also includes a slot-style event that can alter skill levels or the number of skills, adding chance to the character-building loop.

What is Petit Petit Petit?

Control immune cells and medical nanomachines in battles against pathogens threatening unknown creatures.

Each character has distinct equipment and abilities, offering different combinations to choose from. Attacks use skills with cartoon-style sound words, while enemies can target vulnerable points and lower the character’s vital signs. Responding to SOS signals is part of managing those threats. Power-up kits develop skills, and a slot-style event can raise skill levels or increase the number of skills available. Collecting more kits supports fights against bosses. Success depends on the chosen character and skill combination, along with strategy and luck.
