Overtime Mode (Dead Rising)

Overtime Mode is unlocked after completing the 72 Hour Mode with Ending A.

Plot
In this mode, Frank West loses his escape ride because of a zombie attack on Ed DeLuca. Isabela Keyes, however, rescues Frank from zombification. Frank awakens in Carlito's Hideout after Isabela saves Frank from the zombie ambush. Isabela then warns Frank that he has been infected and has 24 hours to live. During that time period, Frank must gather supplies for Isabela to create an anti-zombification potion that will temporarily remove the effect from Frank. Minutes later, however, Frank discovers a hole in the clock tower that is filled with zombies. Isabela then tells Frank that she needs 10 queens to make a deterrent (a stink potion) to avoid zombie attacks inside the cave. Isabela and Frank make their descent into what appears to be a long cavern into the unknown. After escaping by vehicle, The duo then has to fight a tank manned by Brock Mason. Isabela is able to handle the tank with a mounted Heavy Machine Gun, while Frank drives the Humvee. Brock goes into manual drive mode, tips the Humvee over and knocks Isabela unconcious. Brock exits the tank and admits to Frank that he was behind the Santa Cabeza incident. Brock engages Frank in hand-to-hand combat, but is eventually knocked into the hundreds of zombies and is eaten alive. Frank yells out into space, while Isabela is trapped on the crashed jeep by a ring of zombies.

Ending Scene
A message appears informing that Isabela and Frank managed to survive, and the story appeared on the news when Frank returned from Willamette. Carlito Keyes, however still had one plan left, one that could wipe out all of North America...that has yet to be unleashed. Frank's interview will have to wait, his story hasn't concluded. We can only assume that this is just the beginning.
