Budget Vertical Shooter. There are A LOT of these, but does this one have what it takes to be a GEM? Ok, It scrolls well, there is no slow down, you can blast a lot of stuff, its colorful and not too difficult., Perfect for budget Game. Plus it had sounds and music at the same time and it feels like an arcade game, not an ST game. It's got a Rob Hubbard Sound Track and it's the same programmer that did Alien Syndrome. Good stuff.
