Cave Story takes you into a rare world where a curious race of innocent rabbit-like creatures, called Mimiga, run free.

You wake up in a dark cave with no memory of who you are, where you came from, or why you're in such a place. Uncovering Mimiga Village, you discover that the once-carefree Mimiga are in danger at the hands of a maniacal scientist.

Their only hope rests squarely on the shoulders of a quiet, amnesiac boy who can't even remember his own name. Take control and learn the origin of this world's power, stop the delusional villain and save the Mimiga!
