72 Hour Mode is the name given to the main game mode of Dead Rising 2. The main game mode is actually around 96 hours (4 days), as there is a full additional day in the game after the military arrive (provided certain requirements are fulfilled), but still before Overtime. Following the case files, the mode will last about 8 and a half hours real time in which the player(s) are allowed to follow the storyline or completely ignore it. Ignoring it however, will cause the game to end upon the arrival of the military, making this route about 6 and a half hours long. __TOC__
