Classic shoot'em up: Xenon 2
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).
You can play Xenon 2 for free on Abandonware DOS.
Input: keyboard
Distributed on: 3,5 floppy disk, 5,25 floppy disk
Review excerpt from Zero Magazine
"On the gameplay side, Xenon 2 has managed to skirt the trap other shoot 'em ups have falle foul of - that is concentrating too much on difficulty. Xenon 2 is geared mor towards playability. Instead of throwing you back to the beginning of the level on dying, you start from roughly where you died. Plus, there's the credit and energy bar system to prolong your game whilst increasing its lasting appeal and addictiveness."
