Enter the next room and photograph the broken cement at the far back (P1). Then photograph the steam that`s coming out of the broken valve around the corner (P2). In the room with the broken cement is a red valve. Take it. Backtrack one more room, climb up the ladder there and enter the red valve. After that, close it by turning the valve. Then you`ll be able to exit these tunnels.
As soon as you get out of the tunnels, turn immediately to the left until you reach a deserted computer. Go uphill near that computer, climb up some rocks and grab the hidden geocache (G1). Now go down the alley where we started. To the left is a locked shed. From now on, we will call it the Sewer Shed. In front of you is another locked building. Take a photo of the damaged window (P3). Make sure to not break it.
Crouch below the valves and follow the wood path all the way to the right. Pass a shoe in the tree and continue walking straight. At a dead end, you`ll find a locked gate to your left with a red access card beneath it. Pick it up. Turn around and you`ll see a building to your right that you passed before. From now on we will call it the Security Building. In front of you near the wooden path is the Generator Building. Follow the street to the right. You`ll see the Main Building to your left, the Secondary Building to your right and the Laboratory at the far back.
Enter the secondary building with your red access card, walk up the stairs there and grab the white access card on a shelf.
Then, take the stairs down again and enter the back room. In a small box near a corner of this room are small bottles of water. Grab one and insert it in the Water Sample Machine in this very room. Then push the button and grab the sealed bottle. Exit the building from where you came from. Enter the laboratory with your access card, walk through the secondary door and enter this sealed bottle in the first machine that you see. Push the button and you`ll soon be rewarded with this achievement.
You`ll also receive a document along with this achievement (D1). There`s also a blue access card lying around the table here somewhere.
In a corner of this room is a kebab roll inside a small box on a table. Eat it to be rewarded with this handsome achievement.
Exit the room and enter the storage on your left with the white card we got earlier. Photograph the mushrooms in the back room there (P4). Exit the laboratory and enter the main building. Try to find the damaged window you took a photo of earlier. There`s a room next to it with another document inside (D2). Leave by using the back door and enter the sewer shed. Turn on the valve until the light is green. Everything is done here. Exit the shed.
Go back into the main building again and find the Steel Factory pipes in a room to your right. Close Pipe 01. Here`s another bit of damaged cement that you should photograph (P5). There`s another machine room in the other wing of this building. You`ll find damaged cement in there (P6) and a valve next to it. Turn it on. You can now go upstairs and push the grit classifier button to get this machine room working.
Enter the generator building we passed earlier. You can`t stay too long in there though. Quickly push the button in this room and take a photo of the broken valve (P7). There`s one building we have not entered yet. And that is the Security Building. Go inside and take a photo of the dirt (P8). Then open both of the pipes in here.
Go up the stairs and photograph the boots in the sand (P9). Then enter the computer room and take a photo of the document on the right (D3). There`s a box beneath it with a CD in it. Take it and enter it into the CD ROM drive at the computer. Click on ‘REPAIR’ and then all the red crossed to repair this plant (R1). When you`re leaving this building, don`t forget to take a photo of the broken floor near the pipes you opened earlier (P10).
Now we`ll have to get this water treatment plant running again. Return to the back room of the Secondary building. Push the Grit Classifier 1, Grit Classifier 2 and Secondary Clarifier 2 button. We`re close to finishing this. Leave through the back door of this building and take a photo of the broken grit classifier to your left (P11). Jump on the turning grit classifier to your right and go straight diagonal across the clarifier. Behind there is a small cellar. Turn the valve and push the button to finally repair this plant (R2) and get this achievement.
Leave the cellar, go through the gate next to it and enter the office building at the far left. Enter the office room to your right and grab the key from the bottom left shelf as well as the coins from the table next to it. Open the opposite door in the hallway with the key and take a photo of the tablet in there (D4).
There`s a soda machine in the hallway here. Buy a drink with the coins from the office. Then take the drink up the stairs and into the control room to get this achievement.
In the control room take a photo of the Lake Stalburg System (P12). Take the keys from the corner of this control room. Then exit the building by using the exit door near the soda machine. Photograph the dead fish in the lake to the left (P13). Then walk along the river to the right to the far far back until you find another geocache (G2). Return to the dead fish and enter the building next to it. Take a photo of the barrels in there (P14). You`ll soon reach some tunnels with a small river in it. Take a photo of the dead fish inside (P15). After that you`ll reach the next module.

Enter the next room. Save the game. You should definitely immediately save your game here before triggering any alarm. Otherwise the next achievement will be unobtainable for you. First, photograph the broken cement next to the door you just passed through (P1). Walk up the stairs and immediately go to the computer at the very left without triggering any alarms.
Enter the following codes here to deactivate all the alarms in this building:
– 6832 (from the computer logfiles)
– 1970 (found on the tablet in the next room)
– 1245 (Building number)
After that, deactivate all alarms in this building and open all the doors by using the computer. You won`t gain the achievement yet, but later when you leave this building.
Photograph the tablet on the table next to you (D1). Then, enter the room next door and take a photo of another tablet that`s lying on the table there (D2). Go back to the entrance hall, go down the stairs and leave by using the exit door.
You`ll find yourself outside near the canal. Walk some time until you see dead fish in the canal next to you. Photograph them (P2). At this time you should also get the Sneaky achievement. Also photograph the broken wooden crossing to the left of the dead fish (P3). Continue walking until you reach a bridge. Take a photo of the couch on the other side of the canal (P4). Before you cross the bridge over the canal though, there is a geocache behind the bush opposite of the bridge (G1).
Cross the bridge and go all the way to the left until you reach a secret building. There`s a USB stick in the computer there which also counts as a document (D3).
Return to the bridge we crossed earlier and walk up the stairs. You`ll find another document on a chest here (D4). Return to the bridge again an continue walking along the canal. Jump into the canal and walk up the stairs behind the sluice gate. Open the little container building up here and photograph the document on the table (D5). Then take the two keys with you and exit the container.
Cross the bridge and enter the electrical building. Photograph the document on the barrel to the right (D6), then look upstairs. Quickly take a photo of the fire (P5) and then turn off the fire by using the switches at the back and pull the fire alarm (R1). Leave the building, turn to the left and take a photo of the collapsed staircase (P6). Climb up the broken staircase and go through the gate with the keys from the office.
Immediately turn to the right and photograph the broken valve by looking down the railing (P7). Don`t enter the building yet, but continue your path by going through a gap in a gate. You`ll soon see some dead fish in a pond to the left. Photograph them (P8). Go all the way back to the large bridge we crossed earlier near the electrical building. Cross it again and enter the tunnels at the far back.
There`s a fire here. Take a photo of it (P9). Crouch up to the fire and turn off the valve (R2). Take a photo of the electrified floor (P10). Use the valve from the sink by entering it near the fire origin and opening the valve. Then turn the gas valve again until the breaker explodes. Turn the gas valve again and you`ll now be able to continue onwards. Take a photo of the collapsed hallway (P11). Then go up the stairs and photograph the note on a box at the far back of the room (D7).
Go up the stairs a bit more, leave the building and photograph the broken ladder next to the other building (P12). Remember these stairs. We`ll come back to them later. Now go all the way down and take a photo of a damaged pillar near the gate (P13). Before you go inside the building though, climb down the ladder to the canal. Go into the tunnels below the bridge and you`ll soon find a geocache hidden there (G2). Return to the ladder and now enter the building, a garage.
In the control room is another note (D8). We`ll have to repair the forklift now. Enter the battery from the shelf next to the forklift into the forklift. Flip the main switch. Grab the fuel from the balcony above the entrance to the garage and fill the forklift with it. Enter the keys and start the motor. Go into the control room and use the barrel to move the forklift below the grate of the garage. Open the grate by using the forklift and leave the garage.
You`ll reach a big area. Go to the canal behind the biker club. Jump down into the canal and photograph the broken cement on top of the canal (P14) and the objects blocking the other side of the canal (P15). In the parking lots opposite of the canal is the third geocache (G3). Go to the building next to the garage. There`s a sewer hole nearby. Photograph the mushrooms inside it (P16). There`s also a bunch of keys in there. Grab them.
Return to the staircase we memorized a while ago. Unlock the door there and photograph the document on the bed to the left (D9) as well as the mushrooms (P17). Return to the sewer hole and enter the building there. To the left is a machine that you have to fix. Turn everything on except Pipe R2, Pipe R3 and the Factory switch. Then pull the main power lever and pull the operator button to repair this machine (R3).
Enter the next room and soon the sewer. Photograph the hole above you (P18) and the broken gate to your right (P19). Then close this sluice gate by turning the valve in order to repair it (R4). Follow the path in the other direction and you`ll soon find some pipes. One of these is broken. Photograph it (P20). This is quite tricky to find though. Crouch into a vent and go all the way through. You`ll reach a hallway with broken cement to the right (P21). Grab a handle and raise the gate in this very room to repair it. Unfortunately, something does not work. Close the door this room from the inside and fix. Crouch behind the mechanism, remove the crowbar and turn the valve again (R5).
Go back to the sluice gate near the point where you fell down and pass through. Photograph the collapsed tunnel at the end (P22). Then open the water gate by turning the valve (R6). Now you`ll be able to open the flood door next to the collapsed tunnel to reach the next module.

Start the minitrain. As soon as you reach a flooded area, take a photo of the flooding (P1). Drive around three corners to reach a building with a big 4 on it. Next to that is some damaged cement (P2). Continue driving, photograph the first leaking pipe (P3), the second leaking pipe (P4) and around the corner the third (P5) and fourth leaking pipe (P6). Make sure to crouch below the third leak, otherwise you`ll die.
You`ll leave the flooded area. Photograph the cave-in (P7) and pull the lever to switch tracks. After the next tunnel you`ll see another building to your left. Go inside and photograph the broken cement (P8). There are also camera batteries inside here. Outside around the corner is some more damaged cement (P9). You`ll soon reach a locked gate. Take a photo of the leak in front of it (P10) and the broken cement to your left (P11).
The building on your right has some codes for you. Go the building on the opposite side and take a photo of the broken window (P12). Enter the building, take the keys and use the code 8453. After that, pull all the levers. Return to your minecart and use the door to the left of the steam leak, that can now be opened with the keys you got. Photograph the broken minecart behind it (P13). At the back is also some broken cement (P14). Also take a photo of the mushroom tunnel back there (P15) and the locked door at the back (P16).
Pull the switch at the back near the locked door and the switch at the front. In the room with the broken minecart, turn the valve and pull the switch next to it. Return to your minecart and push the button in the building next to it. While you`re waiting for the door to open, don`t forget to take a photo of the broken elevator in the center of this hall (P17). Continue driving your minecart. When it is about to enter the poison tunnel, jump off and wait for it to return. Then continue until you again reach the room with the elevator.
Pull the switch next to the gate and drive through the open gate at the opposite side of the hall. Soon the tunnel will start to collapse. Just continue driving, don`t go back, but photograph the collapsed hallway (P18). You`ll soon reach a room with several tracks. When the minecart is about to go right, stop it and go straight instead to find a cave-in (P19). Return to the spot where your minecart waits. Behind it – that`s where you came from – is a hidden ladder. Take it up and photograph the broken cement (P20). Continue driving the minecart, pull the next switch you see and drive through the next longer tunnel until you reach a dead end.
Step out of the minecart and photograph the missing ladder to your left (P21) as well as the broken cement (P22). Then use the chests in this room as an improvised ladder. Up there, photograph the left (P23) and right steam leak (P24). Turn the valve and go through the tunnel to your right. There`s another steam leak here (P25). You`ll soon reach another steam leak (P26). Go back and turn the second valve, turn the valve at the beginning, then the second valve, then the valve at the far far back.
