This is a terrific rendering of Scramble, one which threatens to leave the other Spectrum versions smouldering on the launch-pad.

You can read all about the other games in the Scramble comparison on page 40, but right here is where the real action is.

Cavern Fighter features a frighteningly narrow cavern which requires constant vigilance if you're to avoid crashing into its twisting walls.

Movement is oh-so-smooth, and ah-so-fast. But you don't need a joystick. You can select your own control keys which means you can have a single key to fire your laser, drop bombs, and slow down.

So you can concentrate on obliterating everything that moves without tying your fingers in knots.

All the usual features are there: rockets, fuel dumps, phizzers, fireballs. Get in there and blast them.
