Samurai Warriors is the first title in the series of hack and slash video games created by Koei's Omega Force team based loosely around the Sengoku (`Warring States`) period of Japanese history and it is a sister series of the Dynasty Warriors series. In the basic gameplay of Samurai Warriors, the player takes the role of a single officer in battle and must fend off hordes of enemy soldiers and defeat the enemy commander. The player has at their disposal a range of combo attacks and crowd-clearing special moves known as Musou attacks. The variety of attacks available increase as the character levels up and acquires more superior weapons. The game features a total of 15 characters based on historical figures during the Warring States period of Japan.
