For anyone who missed them first time around, these Acornsoft gems are *not* to be missed. On one disk you get Magic Mushrooms, Maze, Planetoid and Rocket Raid in a superb value-for-money arcade action package.

In Magic Mushrooms you send Murphy leaping, bouncing and sliding around nine screens, collecting mushrooms and dodging monsters. You can also design your own games. Good graphics, some borrowed from Monsters.

Maze is a fast-moving, real-time action game with realistic 3D graphics in which you explore the mazes which make up the security system of a rival company. One of the best of its type.

Planetoid is an excellent copy of an actual arcade game with brilliant graphics, animation, sound and colour. It's classic shoot-'em-up action in which you fight off an alien invasion.

Like Planetoid, Rocket Raid is a copy of an actual arcade game. Here you are flying low in the final approach to your target - the Martians' supply base, protected by anti-rocket missiles and a host of other hazards. Again, good graphics, animation and colour.

In the second of the two Acornsoft compilations launched in collaboration with Superior, and like volume one it's worth every penny.

In this volume, you get four classics, Starship Command, Arcadians, Labyrinth and Meteors, early trail-blazers which have been much imitated but rarely bettered.

Starship Command is an exciting punch-up against attacking alien ships which is best played with a joystick.

Arcadians is a good version of an actual arcade machine in which you have to defend yourself against the lethal dive-bombing tactics of a convoy of aliens. The graphics are slick, and the game can be played by one or two players.

In Meteors, you must glide your laser-ship through a deluge of meteors, not to mention missiles from unfriendly flying saucers.

It's another copy of an arcade machine with fast, smooth graphics and good sound.

Meteors and Arcadians, together with Planetoid and Rocket Raid from volume one, form the pillar of the BBC's reputation for arcade games.
