Ack Ack Attack

Ack Ack Attack - C.Stock (ZX Computing-Jun/Jul 84-Page 13)





HERE'S YOUR CHANCE TO PROVE THAT YOU'RE A HERO! JOIN THE DAM BUSTERS WITH


C.STOCK OF CHELMSFORD.





The enemy are on the offensive. Troops, guns, shells and tanks are pouring


down into the enemy position along a single, heavily defended railway line.


The only chance is for a single, daringly piloted mosquito plane to fly down


the valley and destroy the railway bridge.


You have been selected and briefed for this task and victory or defeat rests


with you.


The valley is randomly generated before the start of the game - this takes


approximately 17 seconds but speeds up the running of the game. Four strings


are defined, two for the valley and two for the guns.


Your plane appears at the top of the screen and the valley scrolls upwards


toward you, as you go you must destroy the guns which are firing at you - 26


points - until you reach the bridge at the end of the valley.


When you drop your bombs the birds eye view changes to a side of the valley


and the trajectory of the bomb is shown followed by the results of your at-


tempts. 100 points are awarded for a hit on the bridge, but beware, 100 points


are lost if you miss the bridge, crash or are hit by the guns. If your score


falls below -300 then the game is over - you failed to halt the attack and all


is lost!


There are many variations on the "scrolling screen" game but type this one in


and I'm sure you'll agree with me that this is one of the best.
