Over the past few days Sega has been releasing new animation projects for Phantasy Star Zero and Sonic Unleashed. The Phantasy Star trailer features both animation and in-game footage, tied to some strange music.
Also released was the finished "Night of the Werehog" short, based on Sonic Unleashed. Expect no voice acting, or plot for that matter. The animation and graphics are brilliant, however, but the whole thing feels too late; it should have been released three weeks ago. See it here.
