Professor Roberts is imprisoned at the Star Fleet Command HQ on the planet Arg. Your job is to extricate him. The snag is, that the complex is split up into sectors, and to infiltrate the sector where the prof is languishing, involves passing through three other sectors.
You must get hold of the appropriate pass to move from one sector to the next. Therein lie the puzzles.
The puzzles are not overly difficult, but the solutions do sometimes require a bit of spotting. EXAMINE is a command used to good effect here, and this adds a lot to the adventure.
Quilled, patched, and illustrated, The Extricator is described as a split screen text and graphics adventure. There are very few graphics, and you can even turn those off, although they are pleasant enough not to want to.
One word of warning! I nearly didn't get as far as reviewing this game, as I got locked into four locations.
