Knights of Valour (simplified Chinese: 三国战纪; traditional Chinese: 三國戰紀; pinyin: Sān Guó Zhàn Jì) is a side-scrolling beat 'em up video game series released by International Games System (IGS). The plot is loosely adapted from the 14th century Chinese historical novel Romance of the Three Kingdoms by Luo Guanzhong, and features the Five Tiger Generals, Zhuge Liang, Diaochan and others as playable characters. The gameplay involves the use of magical powers that are not featured in other games also based on the novel.
The series includes eleven games, including five main titles: Knights of Valour (1999), Knights of Valour 2 (2000), Knights of Valour: The Seven Spirits (2003), Knights of Valour 3 (2011), and the remade Knights of Valour (2015). The original games were developed for arcades and released in Traditional Chinese, Simplified Chinese, Japanese, Korean and English. All but two games in the series ran on the IGS' own PolyGame Master arcade hardware, being KOV The Seven Spirits, which was released on Sammy Corporation's Atomiswave.
