Remove the excess water

As soon as you get out of the vehicle, go to the base. There's nothing interesting to explore in the area. But if you choose to, remember that your oxygen tank has its limitations.

Once you enter the greenhouse, start the decompression process, or your character will start suffocating. It's a very important action that you can't skip.

Follow marked items. If you scan your surroundings the game will show you the exact path. Any items that you'll need to use will be highlighted.

Once you get into the pipe room, you have to pick up a crank, which is on the table right next to the other tools.

Your job is to tighten up a few valves. The first is in the middle of the room. To get to it, go up the stairs. Place the tool in the right place and disable the first pipe.

In the next room, you will encounter a door, but it cannot be unlocked. You have to go down using a trapdoor in the floor.

You'll reach a location flooded with water. There are valves on the right wall that you need to tighten in order to get the greenhouse working again.

Follow the corridors. You can't get lost. The bad pipes can be easily located, as there is hot steam coming out of them. If you approach them, your hero will immediately scream in pain and retreat.

Follow the flooded location until you reach a larger valve. Tighten it and enter a narrow corridor to continue your journey.

Outside, you'll see the changes that have taken place in the greenhouse. You'll see forces that your hero doesn't want to see.

Remember you can use the scanner along the way.

Coloured pipes

After exiting the flooded floor, you will enter a room with colored pipes. Here comes another puzzle. To solve it, you need to focus on three colors - blue, yellow and red.

To proceed with this part of the mission, you need to start the computer. Pick up the crew member card to have access to his equipment. The card will unlock the path ahead.

Let's start with the blue pipe - to reach it, you have to go through the dark room first. Your character will notice goo that covers the surfaces of the room.

Go upstairs and get out of the first building. If you encounter a problem, use a scanner that will show you the way.

When you go outside, look up and you'll see the blue pipe you need to reach. Enter the next room and, using the stairs, get to the top.

At the top, you'll find a device that holds the Blue battery. Take it with you and continue the repairs.

To go for the next battery you have to go through a blocked passageway. You unlock them by scanning the device and placing the plants in such a way to create a narrow corridor. Squeeze on the other side.

You need to scan the device again. You can find it behind the bushes. You need to track it down and scan to unlock the way forward. Exactly the same way as a few seconds earlier.

After that, you'll enter a next area. Look to the left to find a machine with a yellow battery. Walk up to it and pick it up.

You already have two batteries, the puzzle is almost complete, but you still have a long way to go with the red pipe. Let's start with the fact that you have to go to the top. Using ladders and stairs.

Your next task is to tighten the valves at the top floor. You need to explore the area thoroughly so you don't miss anything. The dense fog makes travel in the area significantly difficult.

There are two valves at the top, approach them and tighten them to repair the damage caused.

Once the sprinklers are closed, go down the stairs to the bottom. Stop when you see the door on your left. Use your card and go inside.

There are several floors in this building. Take the stairs all the way down. Eventually, you'll reach the room with the broken glass. Right next to it is a red battery mechanism. Pick it up and go outside.

Once all the necessary batteries have been collected, all that remains is to put them in the right slots.

Choose the colours of the batteries according to the layout of the pipes or according to the colours of the battery seats. We'll give you the exact battery setting. However, you can check them yourself by scanning the mechanism after inserting all the objects.

1. Red - 50;
2. Yellow - 90;
3. Blue - 100.

Escape

Once the battery is properly set, go to the main power supply. Start it by simply moving the lever.

After watching a short cut-scene, you'll know it's time to escape. Use every staircase, open doors, narrow passages and trapdoors in the floors.

The monster is practically no threat to you. Even if you stop somewhere for a while, the monster won't get you and you can continue your escape.

When you get to the room, do the whole procedure - refill the tank, wear your helmet, start decompression and then go outside. Enter the vehicle immediately and continue your journey.
