Yie Ar Kung-Fu II: The Emperor Yie-Gah is the sequel to the famous Yie Ar Kung-Fu. Both games were developed by Konami for the MSX. While the first one was a fighting game, this one is a beat 'em up. You play as Lee Young, a martial arts master and the son of the first game's hero, who must take out self-proclaimed Emperor Yie-Gah and his gang and save China from their evil influence.
The author, Quibus, avoids unnecessary battles with gang members and beats down every boss to defeat Yie-Gah without taking a scratch.
