Chapter 4 has 4 Playboy Magazines:
Playmate 9 – You will find this magazine in the box of playboy magazines on the first stairwell landing leading from the bookstore.
Playmate 2 – You will find this magazine on the floor in the second stairwell from the bookstore. It is just under the stairwell near the mall’s locked front doors where you see the cops scrambling on the street.
Playmate 8 – You will find this magazine on the floor inside the small rooftop shelter. It is to the left of the shelf on the right wall as you round the interior corner.
Playmate 7 – You will find this magazine right at the end of Chapter 4. Before you go up to Joe’s apartment to end the chapter, head downstairs to the basement. It is on the floor in front of a wooden gate door, next to pallet and a bucket. Make sure to get this before exiting the building or you will need to replay the chapter if you miss it. — Thanks for the tip to John & DJ.

Playmate 12 – You will find this magazine on the floor on the right side of the room behind two small wooden chairs and a gated storage area. This will also just be as you start to escort injured Henry.
