Dead Rising/Infinity Mode

Infinity Mode is a mode of game-play that becomes available after completing Overtime Mode. In Infinity Mode, the objective is keep Frank alive for as long as possible.

In Infinity Mode:
 * Frank's health will decrease by one box every 100 real-time seconds (equivalent to 20 minutes of game time). So this means, with twelve blocks of life, Frank can hold out starving to death for four game hours. However, since Frank dies immediately if all his blocks run out, Frank will approximately survive without food for about three game hours (about 15 minutes real time).
 * Frank must survive seven game days (that's fourteen straight real hours)
 * Food/Drink items in the mall do not respawn.
 * There is no save game ability.
 * The PP bar displays the current remaining percentage of Frank's "current" block of health, i.e. the block that will become white when the PP bar empties.
 * Frank's watch and camera is inaccessible
 * Psychopaths and Survivors appear at different locations from where they do during 72 hour mode, and will all attack Frank.

The 5 day and 7 day survivor achievements are only unlockable in Infinity Mode.

Food
There are two distinct sources of food in the Mall:
 * Mall Food: Food that's just sitting around in the mall
 * Psychopath/Survivor Food: Food dropped by psychopaths and survivors when Frank kills them

Food dropped by Psychopaths and Survivors appears in revolving cardboard boxes. These cardboard boxes burst open and expel their contents up and out into the air only when Frank approaches them. (If a box opens when it's near a railing, there's a good chance that at least some of its contents will go over the railing.) Before the box has opened, food items that it contains do not thaw or spoil.

Psychopaths usually drop around seven blocks worth of food, and survivors usually drop around one block worth of food.

Psycopath/Survivor Food
Psychopaths and survivors appear predictably during the first five days, but there's currently no precise guide to the times at which they appear. Let's fix that! When you enter an area, note the time that appears on the screen. If you find a psychopath or survivor, check the table below, and if the time at which you entered the area is earlier than the time in the "Appears" column for that Psycho or survivor, please update the table. Similarly, if you enter an area and find a survivor or psyco later than the time in the "Stops appearing" column for that person, update the table.

In this table, a question mark (?) after a time indicates that this time hasn't been confirmed.

* Barnaby is a Zombie, and so doesn't have a green nameplate like the other survivors and psychos. He should spawn near the blue umbrella.

Tips

 * There are three different health books located around Willamette, each increasing the ability for food to heal, allowing Frank to last longer:
 * One can be found in the empty room next to Crislip's (100% increase),
 * One in The Sinister Read in the Entrance Plaza (E201), and
 * One at Sir Book-A-Lot in the Wonderland Plaza (W204), where you find the Japanese tourists in the normal game (50% increase).
 * It is possible to just gather a lot of food and hide in places. One of the best places is Ned's Knickknackery in the Entrance Plaza. Because it has a door, you can shut the door behind you.
