THE FIVE DIAMONDS OF LIZ

R.L. Stevenson, ex-FBI agent turned private eye, has received a ransom note. His only daughter, Jennifer, has been abducted by a notorious underworld gang in retaliation for having sent their leader, King Dom, up the river. To secure his daughter's freedom, R.L. must recover the priceless Black Panther Diamonds--stolen from a famous Hollywood film star by a rival gang--and deliver them to King Dom's hideout within 24 hours. Or it's curtains for Jennifer.

GAME PLAY: As a sharpshooter and the world's foremost expert in the use of the Zapper Light Gun Attachment, you must help R.L. Stevenson find the five Black Panther Diamonds, often referred to as the "Five Diamonds of Liz." Your race with time will take you through four dangerous levels--city, sky, sea, and jungle--during which many obstacles will cross your path: falling rocks, explosions, time bombs, killer sharks, poison bugs, alligators, and oddly enough, a plump and juicy roast chicken. Will you beat the clock? Or will time run out for Jennifer? Are you the sharpshooter you claim to be? Or just another flatfoot in a wrinkled trenchcoat?
