The episodic approach sees the action-RPG split into five parts, with the first episode available for free. The downloadable and disc-based editions offer identical functionality, including saved game compatibility, multiplayer and downloadable content support.

No word yet as to when the other four episodes will hit, or how much they'll run. Update: Destructoid reports that players who reach the end of an episode will be prompted in-game to purchase and download the next at 800 Microsoft Points ($10) a pop.
