another thing I just thought of about these older Amiga classics, like Xenon 2, is that, in the MANUAL, there's a story of sorts, something about Xenites or whatever in this case.
Lots of old school gamers loved their well presented manuals, many of which contained BACK stories, and read them before playing (not like today, where no body RTFM!), and played the game with what was written in the manual, in the back of their mind.
I certainly did. :-)
