A well-worn scenario with a couple of extensions: spacecraft rescues sister-ship from alien planet, taking it back to safety on the Blue Moon (all to the strains of the original tune). This is an unashamed zapping game, but with a few differences. There are five stages; each one involves different hazards, from comet storms to the nasty Tecom. It all helps to relieve the monotony - there are fifteen levels of skill too.

Despite the Fire button approach, there are a couple of stages that need skill and concentration. At the beginning you must dock the two parts of your ship before carrying on. If you reach the end, you must land on one of the three landing pads, involving three degrees of difficulty. There's a nice final touch; a flag comes up heralded by another tune. It's fun... but maybe not rivetting.
