Sengoku, or Sengoku Denshou ("Legacy of the Warring States") in Japan, is the first game in a series of Arcade brawlers from SNK that pits a ninja and a cowboy against a horde of feudal Japanese warriors across a post-apocalyptic landscape.
Sengoku was originally released in the Arcades in 1991. It was soon ported to SNK's console, the Neo Geo, and this version would also see a US release. An enhanced version was developed for the Neo Geo CD around the same time, taking advantage of the CD format's better sound quality.
In addition, the game was ported to the Sega Mega-CD by Sammy and the Super Famicom by Data East. These versions suffer from being on less powerful systems, with inferior graphics and fewer features. Neither of these versions were released outside of Japan.
Sengoku was followed by Sengoku 2 and Sengoku 3. It was also released as part of the SNK Arcade Classics 1 compilation in 2008, and the Neo Geo version was added to the Wii's Virtual Console in 2013.
The game is a standard side-scrolling brawler. The player, as either Dan or Bill, must defeat groups of enemies before they are allowed to move forward. A second player can take control of the other character. Enemies occasionally drop power-ups that provide various benefits:
In addition, the player is able to transform into three forms: A quick but less powerful wolf form that can damage enemies by leaping; a strong samurai form that towers over most enemies; and a ninja form that can beat enemies into submission with its fast attacks. These can be selected and used in game, but only sparingly. In the SNES version, these transformations appear randomly alongside the orb power-ups and wear off after a while.
