Log 11 - Near the first upgrade station you come upon, in the room with the excavator.

Chapter 5: Bastion Defenses
Log 27 - Soon after the level begins a cutscene will occur involving a bald dude. Ok maybe that’s not a distinguishing figure in this game, but you understand. Take out the creepers then look inside this tube.
Log 01 - Between finding the second and third power cell, you’ll come upon this tunnel with two machine guns at the entrance. You can find the log several yards to the right of this entrance.

Log 19 - When you enter the large pumping station room, stay on the top level and move to the back.
Log 38 - At the monorail station (left of the upgrade station) you can see a log on the other side of the platform. A running leap will get you across.
Chapter 7: Ice Mines
Log 15 - This one’s found a few feet away from the upgrade station at the start of the level.
Log 16 - After the big showdown at the multi-level administration offices you’ll encounter some stairs and an alternate path to the right. Follow the latter to the audio log.
Log 17 - Just after the cutscene with the corporal, take the stairs that lead up and to the left. Follow this path until you see a small door on your left that leads to a room with a massive claw. On the lower level of this room you’ll find this log.
Chapter 8: Infection
Log 12 - Near the first infected building, under the big flat screen near the first upgrade station you come across.
Log 13 - If you are destroying the buildings in the suggested order, on your way to the third one you’ll see this small structure with a few plants inside. The audio log is just to the right of these plants.
Log 14 - If you are destroying the buildings in the suggested order, you will see a non-infected building next to the fourth infected one. Along the right side of that building you’ll find this log. Depending on how the battle just went, it may be covered in rubble.
