I have ben playing DeadRising on the xbox 360 for a while now, and I have to ask how to onlock overtime mode. I have done all of the missions and saved I think 25 to 40 people, when I get to the helipad ad noon on the last day the chopper dude looks at the pad with binoculars and says somthing like, "There's no way he survived. if he is dead he's dead," and gets killed. it is frustrating and it is really making me mad I have seen that cutseen 5 times! please help.
I think there's a specific time on the 3rd day that you have to talk to that girl(forgot her name), get this cutscene, then go back to the helipad. I'm not sure though. If you need help you should see an online walkthrough, here's a good one.
