Samurai Shodown: Edge of Destiny, known as Samurai Spirits Sen in Japan, is the fourth 3D game in SNK's popular Samurai Shodown series of versus fighting games and the eleventh title in the series. The developer K2 LLC is best known in America to have developed various installments to the stealth game series Tenchu, beginning with Tenchu: Wrath of Heaven, the series' third installment. The main artist for the Samurai Shodown 64 series and Samurai Shodown: Warriors Rage, Senri Kita, returns for official illustrations.
The game was first announced to the public at Tokyo Game Show 2007, as a future release for Japanese arcades. Since late October 2007, the game has been undergoing severe beta testing around arcades in Japan. On December 13, 2007, the official website to the game was created, along with a bulletin of four locations sites which are in Tokyo, Kanagawa, Osaka, and Chiba. Testing begins on December 20th and ends on December 24th. The official site also confirms an eventual release in 2008. The first overseas testing location took place in Hong Kong during December 20~21. Along with this announcement came the game's international title. Aoi Nanase, character designer to the series' first OVA, has reported in her personal blog that the official staff intend to take a great departure from the Makai and are going for a sengoku-jidai effect.
On February 9, 2008 the third location testing ad was listed on the Japanese official site at four different locations. Testing begins February 14th and ends on February 19th. The ad also says that this is meant to be the final round of testing. Also at this time, a tentative release date listed as "Spring 2008" (later to the release date) in Japanese arcades is scheduled on the Hong Kong SNK Playmore site.
As of December 2007, there is little other news of an international release. There is also no news yet when the game takes place in the series storyline
