Deadline was a game of many "firsts" for Infocom: their first mystery game, their first non-Zork game, and the game that started their tradition of feelies.
Infocom gave Deadline a difficulty rating of "Expert", largely due to the abundance of evidence and false leads to be sorted out within a short timespan.
Working titles during the game's development included Was It Murder? and Who Killed Marshall Robner?
