After the awful Jailbreak conversion, this restores Konami's credibility. Its graphics are excellent and sound is great too, with the choice of having a delightful tune play or just sound effects with loud explosions.
The graphics are not up to much either, consisting of a poorly executed 3D effect and badly animated one-colour sprites. If you only have a few quid to spare, I suggest going for one of the better budget releases about.
A disaster. I'm currently in the first month of the year and I already have a contender (if not outright winner) for my worst game of 1987. I was expecting great things but, had someone not written the name on the box, I wouldn't have recognised it at all!
