Cave Story

A side-scrolling platformer in which a robot traverses a strange world that has been thrown into disorder due to its violent history and a doctor that is attempting to exploit the inhabitants to aid him in his own pursuit for power.

The player character awakens in a cave with no memory of how he came to be there. He finds a village of Mimigas, who are being persecuted by the Doctor. The Doctor's servants Misery and Balrog are looking for Sue Sakamoto, a girl who had been transformed into a Mimiga.
