Fire at the enemy ship as it flies overhead on its attack run. You score ten points for each direct hit but watch out for the return fire, which is extremely accurate. You can avoid it by moving your base left and right with the Z and X keys.

Fire by pressing RETURN. You have five lives and when you score 100 points you gain an extra life. There are four levels of difficulty, from easy to impossible. Laser Battle was written for the BBC B by C. Fothergill of Gainsborough, Lincs.
