The last promo for Senran Kagura Burst—Marvelous AQL's busty Nintendo 3DS ninja action game—offered almost five minutes in an "extended preview," but 4Gamer is topping that with an extended play clip that nearly hits the 10-minute mark.
Senran Kagura Burst hits Nintendo 3DS in Japan on August 30, and is also being adapted into an anime.
