Core is a problem-solving game, with all the hallmarks of a classic text adventure, but with moving graphics. You start with nothing but a battery-operated life support system, and have to find a variety of objects to enable you to delve further into the game. Obvious essential items to find include a laser gun, armoured reflectors and, the reason for your doing all this, bits of broken computer to be reassembled.
The game is icon-driven, saveable (thankfully), and graphically excellent. A must if you like adventures.
