It's Deadline, and it puts you, the keen-eyed sleuth, against a 12-hour time limit to solve a classic locked-door mystery. Armed only with the clues inside this package and your own wits, you must sift through myriads of evidence and motives 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.
Deadline is one of Infocom's most difficult games, and requires a number of playthroughs to win. Important events happen at specific times of day, and you have to know about them and be in the right place at the right time to take advantage. It's easy to miss evidence or misunderstand it. There's limited time to complete your investigation. And, of course, you can ruin everything by arresting the wrong person.
The things that make the game difficult are also the things that make it great. Instead of offering an underpopulated world full of set-piece puzzles, Deadline challenges the player to make sense of a coherent reality full of active people and sometimes misleading clues. Characters move around the house, pursuing their own agendas. People have a schedule and plans of their own.
