Locate and activate all three generators to power the bunker.
Objective: Reach the bunker island
Objective: Power up the generators to restore the bunker
First you need to hack the bridge to get across it, then you'll need to activate three generators. Let's start with the generator on the far right (it's marked on your map). Once you collected the audio log from the front of the building head around to the northeast side to find a lift. Lower it, get in and raise it fully. Climb the ladder on the left to the get to the roof.
Climb the second ladder and move around the fenced area to access the camera on the left. Focus on the second camera to the right and unlock the gate using the hacking point. Go through the gate and blow up the tanks ahead to get access to the ramp.
Down the ramp you'll find a fenced area with a generator. Activate it and go back to the ground, use the lift and climb over the carrier to the right.
Now go southeast to the nearest waypoint. If you see a carrier on the east side you can lower it enter an alley on the right where you'll find an audio log.
Go down the north side of the river so you're almost due east of the waypoint. There's a garage door on the right which you should open before climbing into the water and into the building through a door. Climb up on the boat and out through the garage door on the left. Near the dock you can use the boat to climb up onto the dock area. Now head to the fenced area to activate the second generator.
Now go to the northwest side of the lot to find the third and final generator. Open the gate by accessing the camera above it and hacking the carrier below. It will reveal another camera which you access and move up for a third camera. Move it up to access the carrier and lift it up and unlock the panel just behind the carrier.
Go through the gate and over the green carrier. You need to reach the top of the carrier by hacking the crane. Get on the green carrier and climb to the other carrier and hack the crane to move it. Drop off and go through the green carrier but turn around and look under it for another audio log before you move on. There's another fenced area with another generator switch.
Objective: Enter the bunker
Objective: Search for the power controls
Objective: Power up the bunker
Over at the last waypoint you should open the door to the carrier and move it to open the door again. Go down the stairs and hack the laptop and help yourself to the Jam COMs behind it. Go back upstairs for more Jam COMs on the desk and activate the power in the bunker.
