Back in working order, Mikro-Gen has started its new career within CDS with a retrospective of past glories. One, Pyjamarama, has appeared more than once before on compilations, but it's still a great game, the first of the Wally series and a pig to solve. Battle Of The Planets (March '86) is a swift vector graphics shoot 'em up, neatly put together. The others, though aren't quite as special. Frost Byte is an arcadier update of the Wally's, less sophisticated and not much fun. And Stainless Steel (Oct '86) is a very dull shooter indeed. A solid collection, but if you only know the Wally games don't expect the same standard.
