Samurai Spirits Sen

Released in March 2008.

Developed by 'K2 LLC'.

Known outside Japan as "Samurai Shodown - Edge of Destiny"

The game was first announced in development to the public at the All Nippon Amusement Machine Operator's Union (AOU) 2006 event where it was given a tentative release date of sometime by the end of 2007. However, at the 2007 Tokyo Game Show, the date was pushed back, but was mentioned to be nearly ready for future release in 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 4 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 3rd location testing ad was listed on the Japanese official site at 4 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.
