The first fork in the corridor, left will take you to the water plant area, right will take you to the office area
For the water plant turn off 4 valves located here, 3 on platforms one ground level.

For the office you have several objectives, a usb drive on desk (red), the computer to upload (green) The cassette tape on a table (blue) and another USB drive on a table (yellow)

Similarly to #2 you'll encounter a fork in the corridor, left is to the "3 light door corridor" to the right is the Firing Range and the "industrial corridor"
in the 3 door corridor you'll find the following

Tape player and USB

The scan room, stand on the circular plate, wait, then use the computer to upload

The control room, there is a USB here

Before the industrial corridor you'll see the firing range where you can find a USB

Heading to back the industrial corridor you'll want to head into the door in the middle then down this corridor and the room on your left has a valve to turn for the objective.

The two switches are located on the top floor of these buildings, on the wall

Pretty straightforward, photograph the 3 containers.

Spider head to photograph as you enter the outpost, you can't miss it.


The Artifact is located in the last red and white tent on the right hand side. There is a Spiders head to photograph in the last green military tent.

There is a Spiders head to photograph here (there's also a vending machine in the room behind it)

I think this can be also in the control room , But I've seen it most commonly in the 3 levelled "stairs" room that's located when travelling between installations, easier to highlight it in the map and it'll lead you right to wherever it is located.
