SummaryNot even remotely as good as its successor.
The GoodXenon is just not really a very good game. It's wasn't even close in popularity to its magnificent successor, and is quite terrible in comparison.
Being a typical overhead shooter Xenon is quite fun at first, but it dwindles soon enough. Only genuinely good thing about it is its decent controls (if not terribly good).
The BadHowever, Xenon fails when it comes to both graphics and sound. Visually the game is, to say the least, less than appealing. It's blue all over, and the enemies do not contrast well with the background. It's so lacking in colour that you won't really realize you're moving through the game - everything just looks the same.
Musically it's not really better - plain and simple sound effects don't add a great deal to the atmosphere, and the complete lack of background music is annoying as hell. Xenon's level design isn't terribly good either, for that matter.
The Bottom LineThis game just goes to show that a sequel is not always inferiour.
