I was interested to see this having reviewed Super Pipeline II for the Amstrad recently.
The plot is more or less the same, with a tangle of pipes growing from the top of the screen to barrels at the bottom. The idea is to fill the barrels with water. Unfortunately, up a ladder at the side of the screen, trog a variety of nasties whose sole aim in life is to put a bung in your pipe, thereby blocking it. Very painful! Your only weapon is your trusty spanner which can be thrown at them if you're lucky.
From below, the dreaded hard case lobster also crawls up your pipe. So one way and another you soon acquire a bung. Now you must collect a workman to repair the damage, and protect him from the nasties, whilst still shooting them on the ladder. All very complex, and good fun. Success promotes you to an even more complicated pipe.
Graphically, this exploits all that the Spectrum is capable of in 2-D, and the sprites move smoothly, controlled by a variety of joysticks. Enjoyable, though without the graphic excellence and humour of the Amstrad implementation.
There is an added bonus on the tape with an alien zapper, SOS, included too. You must boost down to a planet's surface avoiding the aliens, collect the people, and return to the mother ship. A good game though the movement is very flickery in comparison to Pipeline. Fun and good value.
