Despite its title, this gameis not a philosophical discourse on whether a machine has a soul - score 100 points for each deterministic fallacy disproved, it's instead one of those games where you enter the lair of an evil genius in order to save mankind.
On the face of it, Soul is an ordinary arcade adventure featuring Mastertronic's improved graphics. There's the usual series of obstacled rooms to get through, filled with mobile nasties, and commands to fire and pick up useful objects. However, you won't get out of a section until you find the key. Since both these objects are fairly well hidden, players might find themselves doing a lot of wandering around before finding them.
Luckily, the constant buffering you get from the nasties doesn't mean you lose a life, it just diminishes your energy. But be warned! I had to restart the game when my robot got itself stuck between a platform and a spaceship!
