Ignition Entertainment and Marvelous Entertainment have announced that Muramasa: The Demon Blade, a video game developed by Vanillaware, will hit the store shelves in North America in September 2009, exclusively for Nintendo Wii. Based on ancient Japanese lore, Muramasa: The Demon Blade plunges players into the mystical Genroku era, ruled by the skilled shogun Tsunayoshi Tokogawa. But this culture is threatened; Tokogawa's thirst for power leads to a conflict over the enormously powerful, though cursed, Demon Blades. Players take on the role of a male ninja or female kunoichi, utilising their ninja prowess to traverse the clever side-scrolling levels that feature vertical progression as well as the traditional horizontal stage advancement. Muramasa: The Demon Blade is due to be published in Europe by Rising Star Games.
