Unloading cargo may not seem the most exciting job in the world, but


when a helicopter is just waiting to steal the crates you've unloaded,


the situation becomes somewhat more interesting!





A ship has just docked and you, the man with the trolley, must unload


the cargo, one crate at a time, before the helicopter has a chance to


steal any.





At the end of the pier there is a gun to fire at the helicopter.


Sorry, but for every pass of the helicopter you only get three shots -


any more and the game would be too easy.





Because the helicopter is bigger than you it can carry two crates of


cargo to your one.





All instructions are explained in the program.





For people with issue one SPECTRUM you can change line 130 IF


INKEY$="0" to IF IN 61436=254; the rest of the line is the same. Using


the IN command enables you to keep your fingers on the key that


controls the man with the trolley and fire the gun at the same time.
