This rapid-fire space shooter is surprisingly fun and addictive. Your mission is to destroy 16 satellites, but you'll encounter asteroids, robots, and other adversaries as well. The screen scrolls in all directions, letting you fly around freely. It's easy to locate the satellites because they send light beams between each other. Still, it would have been nice to have an on-screen counter indicating how many remain. While the basic gameplay is simple, Zone Ranger has a lot of extra elements which spice things up. "Sonic sparklers" make you temporarily invincible, and portals allow you to bypass levels. There are even cool maze stages. The graphics are great - all objects are multi-colored and well defined. I even like the control scheme - holding down a button to rapid fire is quite satisfying. Zone Ranger is an exciting shooter. Check it out.
