Sega Master System / Mark III / Game Gear
Dust down your trusty Sega Light Phaser and ready yourself for a challenging game of target shooting. The object is pretty simple. A soldier travels along a railway track and it's your job to defend him with your light-powered firearm. Various meanies travel around the screen and it's their aim to do away with the soldier hero. It's your job to just keep blowing them away!
Rescue Mission comes highly recommended, combining graphical excellence with infuriatingly addictive gameplay. The action is slick and fast and should keep you blasting away for ages. Go get it, you'll love it!
