Xenon 2: Megablast is a classic shoot'em up developed by Bitmap Brothers and released by Image Works in 1990 for DOS and for a plethora of other systems. Xenon was good, Xenon 2 was far better. Compared to today standards Xenon 2 is perhaps a mediocre shoot 'em up, but at the time every shooter fan loved it. Plus, it was developed by Bitmap Brothers (you can recognize the Bitmap Brothers graphics style just looking at the screenshots).
