Highway Hunter

The Good
In highway-hunter you control a car instead of a spaceship/plane. It's a simple but effective variation which sets it apart from most other top-down shooters.
Otherwise, however, game-play mechanics sticks to the basic formula. Collect power-ups, blow up enemies and defeat end-of-the-level boss. Fortunately, all levels have their own respective backgrounds and layouts with various mood-enhancing soundtracks which will ensure to keep you motivated to play.

The Bad
The only real downside I can think of is that it can be quite a tedious affair to beat some of the bosses unless you have any of the more powerful weapon-upgrades.

The Bottom Line
Highway-hunter is a fairly ordinary top-down shooter but it certainly is one of the better of it's kind. It's fun to play every now and then when you have some spare-time to kill.
