"The Incomplete Works of Infocom, Inc." Catalog:

It's been called "part of the latest craze in home computing" (TIME magazine), an "amazing feat of programming" (THE NEW YORK TIMES) and the "Best Adventure of 1983" (ELECTRONIC GAMES). It's DEADLINE and it pits you, the keen-eyed sleuth, against a 12-hour time limit to solve a classic locked-door mystery. Infocom literally puts the case in your hands, providing you with a dossier containing lab reports, police findings, dastardly-looking pills and more. Once you embark on your investigation, you must sift through a myriad of clues and motives in order to track down the killer. No easy feat, for all six of your suspects exercise free will - coming and going, scheming and maneuvering independently of your actions. And some of these personalities are so treacherous that, should you make the wrong move, one of them may do you in. EXPERT LEVEL
