LAZER BARS (aka. Laser Attack) The space invaders above you drop laser bars which you cannot pass. By blasting the ground beneath them you weaken their foundation and can then blast away the bottom of a bar. Once that has been done they can be destroyed if you stand beneath them and fire upwards. You will suffocate if a laser bar or the earth is directly above you. Move left with 1, right with 0, down with 2 and up with M. Blast left with 3, right with 8 and upwards with 9. Your aim is to survive for as long as possible, gaining points by shooting invaders and laser bars. Written for the 16K Spectrum by Alexander McKehnie of Harpenden, Hertfordshire.
