Oneiros 100% Achievement + Full Walkthrough

Introduction

My walkthrough doesn’t show where you can get non-story achievments. To see how to obtain them, check other parts of the guide. Games achievmens are the achievments, for which you need to play a game.

I recommend to create an extra save file at the beginning of each chapter (except the first one) in order to be able to access them quickly. I provide shortcuts to the achievments, so you won’t have to replay the chapter to access them.

Chapter I Walkthrough

Turn right and click on the door. Turn right again and click on a slightly opened door (second from the left). Go inside and click on the toilet. Pick up the key.

Go back and use the key on the exit door. Go forward, then turn left and go forward until you reach a closed door.

Look at the writings on the walls. Turn left and approach a ticket office. Look at the screens on top of it.

Now you have all the clues you need to open the door. The code is

5163.

Go forward until you enter a room with a lever. Interact with it. A door will appear in front of you. You can find a key to this door at the back of the lever.

Pick up the key and use it on the door. Go forward. This is where this chapter ends.

Chapter II Walkthrough

Pick up the clipboard from the floor. On it you can see some clues that can help you progress through the chapter.

Go to the left side of the bed. Click on the metal box. Open the right wardrobe door. Inside you will find a block game. Pick it up. Use it.

You need to move the blocks in order to put a block with a key on a panel with a lock. After solving this puzzle you will find a torn piece of paper inside.

Go towards the exit door and use the light switch (on the right). Go to the right side of the bed and turn off the bedside lamp. Now you will be able to see the writing on the wall under the bottom shelf. Approach the table and click on the laptop. The password is:

unicorn.

Click on the Gallery folder and look at the photographs. One of them has a clue for the lock on the metal box. Go to the box and open it. The code is:

To the right of the box you can find a painting. Click on it.

Find an exit from the room and go forward. Turn right the first time possible. You will encounter a memory. Go forward, a corridor will make a turn to the right. Continue walking for a bit and turn right the first time possible. Then turn left and go forward. You will encounter another memory.

A corridor will make a turn to the left. Walk for a bit and turn left the first time possible. Go forward, the corridor will make a turn to the right. Go forward, then turn left. The corridor will make a turn to the right and then a turn to the left. You should end up on the crossroads with two gears lying on the ground.

Pick the left one (medium red gear) up. Go to the left, then to the right. Pick up another medium red gear and a medium green gear a bit further.

Go back, turn to the left and go forward. You will encounter a memory and find two connected boxes. Pick up a small blue gear, that is lying on the ground inbetween these boxes. Go left a bit and pick up a large blue gear from the ground. Go to the left box. Open the door and take a medium green gear.

Now you need to put the gears onto their places. After placing a gear make sure that the arrow on it points at the arrow near it. I recommend doing it in this order:

both green gears, big blue gear, both red gears, small right gear. After placing all the gears, pull a lever on the left. Approach the right box and click on the button. Pick up a key.

From here go to the right then turn right. The corridor will turn to the left. Walk for a bit and turn left the first time possible. The corridor will turn to the right and then to the left. You will encounter another memory. Go forward and soon you will see a door. Use the key on it.

The first part of this sequence is pretty linear. Go forward, use the trigger and go forward. You will encounter a memory. Go to the end of the road and fall down on a platform. Use the trigger. You will fall on a wall that is dividing two triggers. Use the trigger on the right.

Go down by the black platform. On the left you will see a moving platform. Use it to get to the next trigger. Jump on some more moving platforms and use the trugger. Pull the lever. Pull the next lever. A platform will start going down. You need to pull the lever and get on this platform before it goes too far up. Approach two levers.

You need to pull the left lever, wait until the closest platform approaches you, then pull it again. After that quickly jump on the first platform, then on the second and on the third. The third platform wil take you to the road, that ends in a big room.

Use the trigger in the left corner. Turn left and go forward until you find a lever. Pull it. Turn around and go forward until you find another lever. Pull it. Now you need to pull the first lever and go through an opened passage (a bit back and to the right). Go forward and use the trigger. Pull the lever. A big cube will go up, revealig a trigger. Click on it. Go all the way forward, then right. Click on the trigger. Pull the lever, go upstairs and to the platform below. Use the trigger. Find an exit from this room.

Follow the road. Step on a black platform, then pull the lever. This platform will take you to an island. Jump from the platform, approach three levers and pull all of them. Go forward until you see two levers. Pull both of them. Go back a bit, turn left and towards two other levers.

First, you need to pull the left lever. Go to the black stairs (on the left) and jump on a platform to get a key. Go back to the levers. Pull the right one. Wait for the stairs to stop moving. Pull both levers and go onto the stairs. Jump on the platform with the door when the stairs approach it. Use the key on the door.

Gaming Achievments

You can find the game Unicorn’s Revenge on the laptop (password:

unicorn) in chapter two. It’s a platformer, in which you need to shoot enemies with the rainbow.

The bar on the upper right corner on the screen shows how much rainbow you have. Candies refill your rainbow. Finish the game in order to get the achievment.

You can find this game on the laptop (password:

unicorn) in chapter two. You need to score over 5000 points in Miami Street Skater 3. Perform tricks and collect coins to get extra points.

Press space to jump and shift to do a trick. Apparently, there are other buttons that work, but I couldn’t make them work and only used these two. Make sure to not hold shift when you are on the ground.

Each coin gives a 1000 points so collecting them is important. I got really lucky and had three coins in a row, so I got the achievment pretty quickly.

You can find this game in the big hall near the photobooth in chapter four.

Use left mouse button to destroy panels, use right mouse button to rotate the object. Finish the game in order to get the achievment.

Other Achievments

Go to the other island. Approach a big dark stone to the right (there are a memory and a rat cage nearby). Postion yourself facing the stone, turn left and go forward. You will find an egg in the grass. Pick it up.

In the workshop you can find a clock near the entrance. Every hour (at xx:00) a bird will fly from it. You need to click on it to get the achievment. You you miss it, you will have to wait an hour to try again. Literal houh, since the time on the clock is the same as on your PC.

You can save the game there and return later or just walk around waiting for the right time. Changing time on your PC won’t help.

You need to feed all the snacks you can find to the bird.

Near the house you can find two sunflowers.

In the cellar (code

4762) you can find three corns.

Keep feeding the bird until you get the achievment.

Go inside any bathroom and click on the toilet. You can only do it in chapter four.

You need to see all the movies in chapter four. Go to the cashier and purchase all six tickets. You will need 32 euros to do that.

Look at the screens to see which movie is shown in which room. Visit each room. You don’t have to actually watch these movies. Simply walk in, approach the screen and go to the next room.
