Hydroelectric Dam

Comics #1: Foreign Element

Before you go under the bridge, turn right from the riverbank. Near the overturned car lies the comics book.

Shiv Door

As you walk up the stairs to the dam, this door will be right in your path. Use your shiv to open it and pick up additives and parts for the workbench.

Achievement “Left Hanging”

When you get across the dam to Ellie, she’ll offer to high-five you. Just walk by and ignore her to get this achievement.

Optional Conversation #1

From where Ellie offered to high-five, jump to the left and walk forward to find the grave. Examine it to hear this dialogue.

Artifact #1: Plant Schematics

Continue forward until you see a yellow bulldozer. There is a small brick structure in front of it with a map hanging inside.

Optional Conversation #2

After passing through the gate, go over to the horses with Ellie to listen to this dialogue.

Optional Conversation #3

Follow Tommy until he walks over to the bag to get something. At this point, a dialogue icon will appear.

Optional Conversation #4

Once outside and up to the top of the dam, go to the right side to talk to the female sentinel.

Achievement “Who’s A Good Boy?”

Before entering the next building, you will see a dog. Scratch it behind the ear to get this achievement.


Enter the building with Tommy and go to the nook on the left to find this workbench.

Training Manuals: Smoke – Chemistry

On the overturned locker near the workbench is a tutorial that improves smoke bombs. Now the smoke from them will last 10 seconds longer.

Firefly Pendant #1: Oliverio

Go down the stairs near the workbench and look in the room on the right to find this pendant on the floor.

Artifact #2: Plant Schematics

During the skirmish with the Hunters, you can go back to the room with the workbench and pick up the power plant plans from the table. Previously, you couldn’t do this because the workers were studying them.

Ranch House

Firefly Pendant #2: B. Pino

After you get to the ranch, go inside the house and go to the far right room on the first floor. The pendant lies on the table.

Comics #2: Zero Point

Go up to the second floor and pick up the comics book from the closet by the window in the bedroom.
