The Magnum Light Phaser was released later on in the Amstrads' life, and retailed for £24.99 in the UK.
It came supplied with a cassette and a disk, both containing six games.
The main reason to buy this gun was for the excellent Amstrad conversion of Operation Wolf. Playing this with a light gun on your Arnold was the arcade experience people relished but rarely got back in the 80's.
The other supplied games were fun for a while, but by far the high point was Operation Wolf.
