While on the helicopter at the beginning, take a picture of the gas station as it explodes to get more PP. Also, take a picture of the women being tackled off the roof as she is in the air to get more PP points.

When you first come out of the vents to the rooftop at the beginning, turn left and go to the far end of the roof. A woman named Natalie will be standing there. Talk to her and make her follow you (kicking the soccer ball at her is also something you can try). Take her to the other side of the roof where the elevator is located, then go to the far end there. You will see a man named Jeff creeping around the dumpster. Immediately take out your camera. Quickly take a picture of the two of them hugging and kissing for 10,000 PP.

In any food area in the mall (for example, Jill's Sandwiches and the Colombian Roastmaster), pick up a frying pan and examine the stove. You will get 2,000 PP for using the stove. When the frying pan is red hot, you can use it to get another 100 PP for every zombie you kill by holding X and burning their face.

The microwaves can cook frozen and uncooked food products with a 2,000 PP bonus (similar to the frying pan). You only get the bonus once for each of the microwaves (six or seven in all), including a 10,000 PP bonus for getting them all. In addition, cooked foods provide more health, but eat it right away or it will spoil.

Enter the Chris' Fine Foods restaurant in the Food Court. Break the large dishes sitting on stands on the east wall for 1,000 PP each and a 10,000 PP bonus for destroying all of them.

In the toy shop, hit the giant servbot until the swirly eyes are lined up with the sad face for 10,000 pp.

Go into the gym across from the hardware store. Knock down the punching bags to get 2,000 PP per bag, and 10,000 PP after you knock down all the bags.

In the gym, run on the treadmills for 2,000 PP each. You will receive a speed boost and a 10,000 PP bonus for running on all the treadmills. The Gym is also a Safe room. Zombies cannot enter it unless you break the glass.

Repeatedly hit a clothes rack so that it spins to get a 2,000 PP bonus.

Get in the rollercoaster in Wonderland when it is not out of control. Ride on the roller coaster until it stops to get 10,000 PP.

Go to the plaza outside of the warehouse some time on the second day. You will see an intermission sequence showing someone about to murder a trapped girl in a box. After the scene the man is nowhere to be found, but there will be strange people in masks and yellow raincoats that will attack you if you get too close to them. They all have good knives. For every one of these psychopaths you kill, you will get 500 PP. If you see one of them throw up his arms and shout, he will have just lit a stick of dynamite. If you are low on health, run toward him. When he grabs you, shake him off then run. The blast should take out his friends. The best weapon to use against them is a handgun; try to aim for the head. Be careful when fighting them with a melee weapon. They will sometimes try to gas you for capture. If this happens, you are not dead but will lose all your weapons and must escape. After you are out of the box, go directly ahead. Grab the folding chair and walk slowly to the large group of worshippers to attract some of them. Try not to alert all of them at once, just about two or three. When that weapon breaks, start to use the jump kick on them. When you have cleared out a good number of them and you have an open path, run towards the carpet they are praying to. On the red carpet is a sword. It should take them out fairly quickly, allowing you to escape.

Kill a Spec Ops to get his machine gun. Go to Seon's Supermarket in Overtime mode. There should be over eight Spec Ops there. Enter the pharmacy and close the double doors leading to the corridor to the pharmacy. They will all stand in front of the door if they see you and not do anything. Go to the window in the front of the pharmacy and shoot them down with the machine gun. To repeat this, get new machine guns from the bodies and exit via the maintenance door in the corridor. Shoot any Spec Op from the front window to make them all crowd in front of the door again. You will get 1,500 PP per Spec Op. You must successfully complete Overtime mode though to keep the PP. Do this after giving Isabella nine Queens and having one in hand for when you decide to finish.
