Phantasy Star Online Episode I & II

Phantasy Star Online Episode I & II is a video game released for the Nintendo GameCube and Xbox. An online hack and slash RPG, its focus is online gameplay rather than storyline.

Multiplayer split-screen mode can be played with up to 4-players, though the framerate and visibility range is much lower than offline single-player and online modes. Playing offline on Xbox requires an active Xbox Live Silver account. Check Phantasy Star Online on "See also" for more details.
