All the home computer ports' manuals include the same written prologue, which offers a very different story from that of the coin-op, playing up the communist imagery already present in the original: "Strider" (Hiryu is never used as his name) is said to be on a mission to infiltrate the Russian Red Army in order to return enemy secrets back to his superiors. The first stage is referred to as "Red Square", where Strider battles out "KGB attacks". After showdowns in the snow-capped peaks of Siberia and the southern lowland jungles, Strider seems to receive new instructions, as he must return to Red Square to defeat the "Grand Master of the Red Army" in order to protect the "future of the western world".
In-game cutscene, on the other hand, remain unchanged from the original, except for the ending which has been rewritten: The game is revealed to be a simulation Hiryu entered as a test to prove his skills before the real invasion. Hiryu is praised for having successfully completed it, something no one believed was possible, and are certain his skills will come in handy once the true invasion starts. Funnily enough, the programmers recycled the images from earlier cutscenes, leading to Ton Pooh and General Mikiel congratulating his enemy for his success.
