"I may make more spin-offs," said Kojima. The Boss (above right), an antagonist in Snake Eater, is a possible candidate for her own game, a title Kojima said he "personally [wants] to do.

Kojima served as executive producer on the Platinum Games-developed Metal Gear spinoff Metal Gear Rising: Revengeance, which launched earlier this week on PlayStation 3 and Xbox 360. Kojima and artist Yoji Shinkawa attended the game's U.K. launch event at a GAME location in London last night.
