A fourth unannounced game, being developed by Resident Evil creator Shinji Mikami, is also in the works, the company said on Wednesday.

The batch of original fresh games is the result of a new development partnership formed between Sega and Platinum Games, which was formed by several reputable Japanese developers including Mikami.

"The creative forces at PlatinumGames bring a new level of imagination into the SEGA family at a pivotal time in the video game industry when the demand for quality, originality and fun has never been greater," said Tatsuya Minami, president of PlatinumGames. "These new titles will contribute meaningfully to SEGA's brand, while adding a new level of depth to the strategic portfolio of games in our library."

The three confirmed games are described as follows:

MADWORLD, the first title set for release in Q1 2009, is an inventive third-person action game exclusively for Wii". Produced by Atsushi Inaba, MADWORLD has a unique black and white style depicting an incredibly sharp backdrop that straddles graphic novels and 3D worlds. As players battle opponents, they must master the use of various weapons and items found within their environment, such as chainsaws and street signs, while entertaining sports commentary adds to the third-person gameplay. With its irreverent humor and over-the-top violence, MADWORLD will deliver a unique core gaming experience currently missing on the Wii system.
