Some time has passed since the defeat of Ashtar and the revived Jaquio. And a certain Irene Lew (obviously either a reporter or a detective, it is not clear), carrying out someone's mission to monitor a strange factory about which no one really knows anything. But on her way there is a person who is very similar to her friend - Ryu Hayabusa. And he kills her. Well, as you understand, it's not him, but just an impostor. Ryu himself got wind of this, who now must at all costs erase the false stain from his honor. In short, he went to the factory in search of answers.
For Lynx, this is a port from the Arcade version of the game, exactly the same as for the NES, but unlike the latter, Lynx has a very shabby graphics, which is what we are seeing.
