Zangeki no Reginleiv (Dynamic Slash, or Dynamic Zan was its original title) is an action game for the Wii developed by Japanese developer Sandlot and published by Nintendo. It was first revealed at Nintendo's conference on October 2, 2008. It was released on February 11, 2010 in Japan; no North American, European, or Australian release dates have been announced. With its black cover design, it is the third game to break the traditional white coverwork of Wii video games. The first two were New Super Mario Bros. Wii and Metroid Prime Trilogy.
The story revolves around spiritual siblings stopping an army of giants.
The game supports free, four player online cooperative play, Wii MotionPlus and the Classic Controller. It also includes weapon customization and more than 300 weapons. The player has the ability to target heads or limbs, then cuts them off with blood effects and all.
Due to the game only being released in Japan, not many outlets have reviewed the game. Famitsu, Japan's weekly gaming magazine, awarded the game a 28/40 with a breakdown of 8/7/7/6. In America, PixlBit awarded the game 4/5 stars citing the game's excellent WiiMotion Plus utilization and the co-operative online mode. Siliconera said that the game is "mindless fun", "so mindless ... people are either going to love it or hate it."
