As soon as you are in control of our protagonist, enter the office to your left until you reach the main hall next to some elevators.
A Bad Case of the Mondays
In order to get this achievement, jump down the railing in the main hall. You'll be rewarded with this achievement as soon as you respawn.
Take your preferred method to reach the eighth floor and enter your office located at the right behind some doors. Take your camera, car keys, helmet and flashlight from the table as well as the cabinet and leave your office. After that return to the elevators in the main hall and take a ride downstairs. As soon as the elevator stops, turn every lever at the control panel to a green position and then leave the elevator.
As soon as you're out, move along the railing in the main hall until you reach the entry to a cafe space. Move downstairs to find more cafe tables. Enter the door that says 'Cafe & Buffet' to reach the kitchen. At the far back of the kitchen is an office with a document inside (C1).
Leave the kitchen by using the emergency staircase and move to the first floor. Don't take the door to the first floor, but the door right next to it. You'll soon reach a more open office. Read the document on the table (C2). Continue your path until you reach the entrance hall on the first floor. Read the document right next to the main entrance (C3).
Move to the reception and take the letter with you. You'll soon reach the elevators. Take the door to the left that reads "Parking Garage Access". Enter it and open another exit door on the same floor behind it to reach a small space in a back alley. Climb up the first ladder, but not the second one. Instead, walk around the ladder and crouch to see a geocache (G1).
Walk back inside the building, take the stairs down to the parking garage and enter your car to complete this chapter.

Walk through the gap in the fence to the left to reach the underside of a bridge. Walk over the planks below the bridge until you see a broken column to the right. Take a picture of it (P1). Continue walking to the end until you reach a Water Flow Box. Repair it (F1). Then take a photo of the broken pillar right next to you (P2). As soon as you walk up the stairs again, jump at the top of the stairs to find a geocache in a niche (G1). After that, return to the place where you started.
This time don't go through the gap in the fence, but continue forward until you reach a staircase that leads downward. Photograph the corrosive barrels next to it (P3). Walk down the stairs and climb down the ladder. Down there, take a photo of the damaged water-gate (P4) as well as the jammed water flow (P5). Then, enter the power plant.
Take a photo of the document lying on the table to the right (C1). Then, walk down to the generators and take a photo of the broken generator (P6). Turn off the left power switch to the left to repair this power plant (R1). Walk the stairs up twice again and enter the door at the back of the hall. Take the bolt cutters inside with you. Go to the room on the middle floor and destroy the chain with the bolt cutters. Then leave the power plant.
Walk along the wooden path until you notice a broken electric line that breaks right in front of you. Photograph it (P7). Continue walking along the path until you reach a small container building. Take a photo of the tilted electric line right next to it (P8). Enter the container and take a photo of the document on the table (C2) as well as the map on the wall (C3).
Leave the office and directly walk to the left. Take a photo of the container that has fallen over (P9). Then walk over the broken bridge, which you have to take a photo of (P10). Walk along the path, but don't go too far yet. Somewhere around the middle there's a secret cave in the bushes to the left. Take a photo of the document inside (C4). Then take a photo of the device on the right (P11). Get out of the cave and continue walking towards the bridge.
Walk below the bridge until you reach a device next to the railway. Turn the button to set the light to red (R2). Then take the geocache from below this device (G2). Go all the way along the rails until you reach a fallen tree. Take a photo of it (P12). Then, cross the railway and walk towards the village. In the middle of the village is a fallen tree you have to take a photo of (P13). From there walk to the left into the bushes till you find a grenade next to a red cart. Take a photo of it (P14), but don't trigger it, otherwise you'll die.
Walk all the way to the end of the road until you reach a cliff. Turn to the left and walk along the side of the cliff to find a cave. Inside is another geocache (G3). Then walk all the way back to the train bridge we crossed earlier. Go down the left of the train bridge to reach a section below the bridge with broken cement. Take a photo of it (P15). Then walk to the building on the opposite side of the railroad and enter it. This is the dam.
At the far back left of the first room is a red fuse. Take it with you to the second room. In the second room is a fuse box with two fuses missing
First Try
To receive this achievement, you have to throw the fuse box from the top of the stairs into the fuse box perfectly. This is kinda difficult to achieve, so this might take a while. You can try as long as you need though.
Afterwards, flip the power switch to repair this device (R3). Then, go through the door on the left to get outside and take a photo of the crack in the dam (P16).
Forseen Consequences
Now save your game. Go into the previous room and take a fire extinguisher or a brick. Throw this gadget against the crack in the dam to be rewarded with this achievement.
Afterwards, take the elevator downstairs to reach the next map.

As soon as you climb out of the elevator, take a picture of it (P1). Enter the office right next to you and turn every button once. Leave the office and take the door on your right that is now unlocked. On a shelf to the right there`s a small package. In it is another fuse box. Grab it and take it with you. Go through the next door. Walk down the stairs and photograph the water puddle (P2).
Leave the building by using the door on the right. Outside, photograph the broken wooden platform above the dam building (P3). Go all the way to the left and enter the dam building again. Turn to the right and enter the next room. To the left is a locked gate. Enter the room next to it and crawl through the vent to reach the room behind the gate. Take the key on top of the box and open the gate with it. Now, use the fuse box here and flip the central lever to open up the next set of doors.
Return to the room with the water puddle and walk up the stairs there again. The laboratory to the right should now be open. Enter it and turn the valve there to repair the leak (R1). Go back to the elevator from the beginning and now take the door on your left.
This room is a mess. There`s electrified water all over it. Take a photo of the collapsed catwalk
(P4) as well as the flooding (P5).
In order to get this achievement, you must clear this platforming challenge and reach the other side of this electrified room. If you're stuck, watch the video walkthrough.
As soon as you've reached the other side of the room, take a photo of the missing cement on the wall (P6) and the broken door right next to it (P7). Open up the lower door to your right and take a photo of the document in this room (C1). Go up the stairs and then into the control room.
In there, listen to the audio tape on the table (C2). Look at the panel to your right and turn every button that has a light next to it to cancel all the overwritten door locks. Open the door next to the sluice gates in the control room and walk along the cave until your way is blocked by rubble. Photograph the rubble (P8).
This is our first step for this achievement. We`re going to connect this dam to the grid again. First push the button on the control room table. Then go to the sluice gates and set both of them to 3000 RPM, so that both lights shine. Then push the button in between the sluice gates. Afterwards, push the two button on the wall of the control room to power the generators. This is all that can be done here. This is only preparation for this achievement though.
Now, go through the exit door and walk along the hallway until you reach a secretary office. Read the document in one of the shelves (C3). Then enter the big office and photograph the map on the wall (C4). Go through the next exit door and photograph the broken cement on the wall (P9). Walk down the stairs and go outside.
You`ll soon reach a tree growing out of the cement. Photograph it (P10). Enter the switchyard breaker room and push both buttons to finally connect this dam to the grid (R2). You should gain the 'Power to the Future' achievement now. Continue your path until you reach a sawmill.
Don`t go into the building yet. First go right around the building. There`s a toilet there. On the right side of the toilet is a geocache, though you can only see it if you crouch (G1). Go back and this time, go left around the building. Take the stairs and then take a ride with the funicular. Photograph it afterwards (P11). Enter the sawmill and directly go to the right. Turn the crank and photograph the hole in the floor afterwards (P12). Open the side door of the sawmill and go into the next room. There´s a newspaper on the table that you have to take a photo of (C5).
Go outside of this room and jump down the railing onto the ground floor. Unlock the main door and then enter the storage room. Take some boxes and climb up on the right platform in order to find a key. Unlock the door below. You`ll find yourself in a room with a lot of doors. Inside a room that is located on the left is another note (C6).
Enter the electricity room next door and go down the stairs. Activate the power and - quickly - go up the stairs again, in order to avoid sudden electrocution. Photograph the electrocuted floor afterwards (P13). Exit the room through the next door.
Exit the sawmill area by climbing up the boxes and jumping above the wall. Next up are the collectibles near the lookout platform. Go up the stairs to the lookout and photograph the broken platform (P14). Also take the geocache from the top of the info signs right next to the lookout (G2).
Go down the stairs again and take a sharp turn right. Continue your path, photograph the broken bridge (P15) and cross it. Again take a turn to the right until you reach the dam again. When you're inside, take a photo of the hole in the wall (P16). In the room behind that hole, you'll have to take a photo of the shelves and the destroyed cement wall next to them (P17).
Return to the bridge we crossed earlier. This time go in the other direction towards the guard`s house. Before we go inside though, we walk past it and take a photo of the fallen tree (P18). Now, let's take a look inside. Go behind the guard's house, climb up the ladder and jump inside by using the window. Photograph the documents on the table (C7) and take the two keys.
Note: There's a key on top of the television which you should take as well. I forgot it in my video guide for this map and picked it up in the video guide for the next map.
Exit the house by using the main door, cross the bridge again and walk to the right until you the stairs leading up to the lookout again. Across from them is another wooden bridge. Take a photo of this damaged bridge (P19). Cross the bridge and walk for a short while until you reach a door to a cave that will lead to the next map. You can open it with the key you found inside the guard`s house earlier.

Enter the next room and take a photo of the corrosive barrels in the corner (P1). Go into the office and photograph the map on the table (C1). Push down all the four levers on the wall, open the small box and set every lever in there to the upper position. After that, push the ON button and then the RESET button. The metal gate outside should now open up.
Go through the gate, take the stairs to the left and you'll reach another small room. Photograph the bottom of the pipes to the left (P2). Enter the small tunnel and you'll immediately notice broken cement on the left side (P3) as well as on the right side of the tunnel (P4). Go all the way straight through the doors and you'll soon find another audio tape (C2). Also don't forget to take the keys from the wall.
Enter the storage room next. On the top right of the shelf there is a fuse that you'll need for the achievement later. Leave it there for now. Open the gate next to you and take a photo of the broken grate on the floor (P5) and another broken grate on the floor (P6). Then, turn the valve and leave the room.
Exit the storage room by using another door that leads to a flood gate. Take a photo of the flooding in front of the flood gate (P7). Then, open the flood gate and enter the flooded pipe room. There are several valves in here. Take a photo of the crack in the A2 pipe near the upper door (P8). In order to solve this puzzle room, you'll need to turn the valves of the pipes A1, A3 and A4 and then push the Water Sensor button. Exit by using the next door.
There's a document on the chest here (C3). Place the valve from the storage room below on the door here and enter the next room. There are three cracks in the cement on the right wall here, at the first and second part of this hallway. Collect the first (P9), second photo (P10) and third photo of these walls (P11). Behind the palette at the far far back of this hallway is another key you'll have to take in order to get an achievement later on.
Now go all the way back to the storage room and take the fuse with you. Go through the door at the back of the room, round the corner and through the flood door. To the right is a water flow meter that you can fix (F1). Then walk up to the lever puzzle:

Walk up the stairs in order to reach an area next to a cliff. Directly on the left is a damaged building. Take a photo (P1). Walk to the opposite side of this small building to find a geocache directly next to the cliff (G1). Walk all the way along the cliff until you find a damaged fence that you must photograph (P2). Continue walking in that direction to find a big amount of trees and bushes. Behind them is a small cave with a geocache inside (G2). There's also a document lying next to it (C1).
Leave the cave and go to the blue door of the huge building next to you. There's a pink card next to that door. Pick it up and open the door with it, entering this pumping station. Go through the next door.
To the left is a staircase, to the right is the main room and in front of you lies the pool room. First, go up the stairs to the left. As soon as you reach the next floor, you can look into the pool room to the left. Take a photo of the broken pipe above the pools (P3). Don't go into the office to the right yet, but continue walking along the railing to find a newspaper (C2). On the balcony next door is another document (C3). Now enter the office, to find another document on the right table (C4). Grab the keys next to it.
Better Than Before
You can earn this achievement by repairing the Pumping Station.
- Go to the computer and open the top left light blue line, the right chlorination line, and the top blue line.
- Go down the stairs, turn left and enter the pool room and fill pool 1 with the button to it's right.
- Turn around, go into the room with the staircase and turn left, and enter the main room. Take a picture of the cement cracks below the light blue pipe (P4) and between pipes A3 and A4 (P5). Go through the door between A1 and A2 or A2 and A3 to enter the pipe room. Then open valves A1 and A2. All the valves in this room should now be open.
- Go behind pipe A4 and grab the blue valve from off the floor. Turn around and go through the door. Turn right, go down the staircase and turn around. Walk forwards until you pass under the pipes, then turn left, slot the valve into the hole and turn it.
- Go back to the broken building from the start of this map. Unlock the door with the key, and turn on the Chlorine Tank.
- Go back under the pipes, turn right and open the red valve.
- Return to the pump room and close valve A4.
- Go back into the pool room, drain pool 4 using the button to it's left, retrieve the key from the bottom of the pool and re-fill it.
- Go back to the pipe room again and open valve A4. All the valves should be open again.
- Return to the blue valve outside and open it again.
- Finally, go back to the computer in the office and open the top red and blue pipes.
The system should now be fully running again, awarding you with the achievement (R1). Go back into the pool room and open the door at the far back. Walk down the stairs and photograph the broken cement (P6). There's a storage room next. Climb up the chests and grab the key from inside the storage room. There's nothing else to do here.
Return to the pipe room and open the gate there with the key you found just now. There's another document behind it (C5). Then, go to the staircase and this time, take the stairs downwards. Open up the hall to the right with the key we found in the water pool earlier to find yourself in a collapsed stairwell. Take a picture of the damage and then save your game. This section is quite hard to do without falling to your death. The trick is not to jump on the first "jump", or you'll hit your head on the roof and won't make the next platform.
After you make it to the ground, walk through the door and photograph the document on your right (C6). Then go into the vent and finish this map.
