"It is an exciting time for the Sonic franchise as we look to reinvent our hero while staying true to the spirit of what made him an industry icon," said Sean Ratcliffe, VP of marketing at Sega.
"Sonic Unleashed will introduce a new, unexpected storyline along with innovative gameplay that compliments traditional skills and features, allowing players to experiment and engage in new ways."
Said innovation will include a twist, says Sega, specifically in that different adventures take place according to the time of day. Additionally, Unleashed promises new combat, movement techniques, functional abilities, and platforming across seven continents in "picturesque" 2.5-D graphics (i.e. seamless 3D backgrounds and perspective merged with 2D perspective).
The game is scheduled for release on Xbox 360, PS3, Wii, and PS2 this holiday.
