A dusty arcade console in a dark corner of an off-licence boots up, passes it's ROM check and is now demanding more than just your money. After studying Galaxian A.I. over a number of years it has assembled firm plans on world domination by unleashing a torrent of fear on it's screen. Your team, having co-incidentally just entered said off-licence, recognise the symptoms and offer to help the owner get it back under control. 15 minutes later, and having infiltrated the offending ROM's sprite code (using the elusive red 48K Spectrum), you must take down 5 waves of baddies by firing character code 138s at raining cherries.
