Simon Hargrave's adventures, starting with Starcrash, a game with a good plot, which I rated at four Dragons in the Dec '87 issue, have by the fourth in the series been enhanced tremendously so that the end product is even more of a professional all-round package.

In The Heir of Tyos in the tradition of the hero having an odd name, you are cast as Krantz Menostu and live on planet Tyos in the Xenopho system. The task is to find the amulet of Tyos to stop a neighbouring King's siege.

You start, when you awake at the top of a pyramid shape -base by a teleporter and the number of locations increase as you progress down the floer levels of the pyramid. In total there are over 200 locations, although despite my best and drastic attempts I have absolutely no idea how many.

Other locations include medical laboratories, where a nurse ominously lurks with a syringe, an apartment, covered balconies and a cafeteria. Plus there's a shattered tube' where vacumn no longer exists and you are promptly sucked to your death.

The reason for my scepticism over any task being simple in this adventure is that instead of merely finding an object and next game going back there you have to search other areas for the item. Not being able to boycott previously unfruitful locations is due to the items are randomly placed.

Complex could be used to describe the commands. GIVE THE SYRINGE TO THE NURSE AFTER REMOVING THE NEEDLE being reminiscent of Juxta-Position.

This is easily the hardest of the series, so give it a try.
