Sega is rolling out TV spots in Japan promoting its femme fatale hack-and-slash action game Bayonetta.   Joystiq is featuring both 15 and 30-second cuts showing how Sega blended live action with in-game scenes for the ads.

The 30-second spots feature a live model in the beginning before transitioning to her in-game model, and eventually game play clips.  The ad then returns to the live model in the finale, blending her in with hi-res CG.  The shorter spots forego game play cuts completely.

The commercials are in Japanese but deliver the English tagline, Nonstop climax action.   The 15 and 30-second cuts run concurrently.

Watch them at Joystiq.
