Kingdom Hearts: Coded

Kingdom Hearts coded was a mobile game that was released in Japan, exclusively on NTT DoCoMo phones. The initial install contained two playable worlds. These were unrelated to the main story, which was released as episodic downloadable content in eight parts.

The first world available upon initial install was Traverse Town, which was a trimmed down version from the main game, and as such was labeled the "special edit upgrade". Sora could fight heartless here. It also acted as a hub world, allowing travel to the only other world available in the initial install, the Olympus Coliseum.

The "Olympus Coliseum Side Episode" was a small story wherein Sora fought battles at the Olympic Coliseum for the satyr trainer Philoctetes. The Disney hero Hercules also made an appearance here.
