Easter Eggs

This is a list of all types of easter eggs in Superliminal.

Secret Rooms
These rooms have no plot-related significance but they're fun to find. Some are necessary to find collectibles (chess pieces, blueprints, etc.).

Locations
Show/Hide Locations (SPOILER) Chapter 2: Found in the room with the giant, cyan king piece. Once aligned and able to be interacted with, the checkered cube and the king piece can be used as steps to reach the overhead doorway. It leads to a hallway with pink wallpaper. At the dead-end there is a trash can with a glowing, red dice inside. Entering this room grants the Please Use the Other Door achievement.

Chapter 2: Found in the room above the moon room. Using the object/s on the moon (the can, cheese, building block and/or doorway), the player can reach the opening in the skylight. This has the contents of a usual behind-the-scenes room: spare wall panels, traffic cones, spotlights, a carpentry workbench, etc.. Unique to this room, there is also six projectors that create the illusion of a night sky. They can be switched on and off, as a single unit, by the player. Additionally, a blueprint can be found here.

Chapter 3: Found in the room with the dice that splits into halves. This room is partially visible in a gap between the two almost-intersecting wall panels. The room can be entered by going over a panel using the dice halves as steps. Nothing is in the room except for a water dispenser. Exiting the room is difficult and a level restart may be necessary.

In the last part of "Labyrinth", Level 7, where you can resize the room you are in, put the smaller room into the lightbulb directly above the model parking space. Remember to go into the smaller model to unlock the hallway you use to access it beforehand. When you walk into the lightbulb room, jump down, and walk backwards. you will find a lot of water dispensers, with a blueprint and a tiny doorway on it

Chapter 8: Found in the first room of this chapter, with the bed and acoustic foam on the walls. Before the secret room can be entered, go into the model room and walk through the hallway at least once (to establish the teleportation between doorways). Now, to enter the secret room, place the same model room back on the table, taking care it's approx. the same size as the other two models. After exiting the hallway, the player is now small enough to enter the rightmost model, labelled "Jungles' Bistro", through a door on its back. It looks like a usual bistro with a stage, a bar and a dining area. On the stage there is a keyboard that the player can play. Also notable, is the bar whose shelves hold only cans found in the Dream Soda vending machine.

Secret Objects
These serve about the same purpose as the secret rooms, having no real significance.

Show/Hide Information (SPOILER) 1. Red Glowing Dice - in the room where you pick up a giant painted green king chess piece. use block and king to get into the upper room. found in the trash.

There is a small hole in the floor in the corner on the left of this trash can. If you make the dice very small and throw it in this hole, the dice will respawn in the trash. No purpose to this feature found yet.

2. Top - at the end of the game, in the room with the light switch, on the top of the broken chess piece. Probably a reference to Inception.

3. Glowing Banana - at the end of the game, in the area with the massive water coolers, if you walk around the top of the barrier, there is a glowing banana wedged in a corner.

4. Rubber Duck - in chapter 3 after the "pulling cubes" room there is a darker room with a tower of pallets on the right side and a bucket where water drips. Inside the bucket there is a rubber duck which bounces and squeaks.

5. Glowing Apple - in chapter 5 in the room with a multiplying apple and fan. Occasionally when multiplying the apple it will change colour when changed enough you have a chance of getting a glowing orange apple.

6. Casino chips - in chapter 7 with the dollhouses, in the room where you need to go through a keyhole, bring both portals with you to the next room where the chessboard is. Use the portals to get to normal size. In the far end of the room to the left there is at able with a blue organizer and a white mug, Behind a mug there is the chip which clones itself.

Literal Easter Eggs
These are all literal easter eggs in the game. However, finding all of them will not grant any achievement.

Locations
Show/Hide Locations (SPOILER) Chapter 2: Found in the section of the pink hallway where the player first takes the emergency exit door off its hinges. Use the door and/or a can from the Dream Soda vending machine to reach the exposed space above the ceiling panel. At the T-intersection past the doorway, the easter egg is on the left. It's pattern is of a blue sky with clouds.

Chapter 2: Found in the outer room encompassing the pink inner-room. Use the emergency exit signs  as ramps to get onto the overhanging, metal bridge. On the bridge there will be a purple egg covered in white stars. This bridge must be crossed eight rooms later though the easter egg will then be replaced by a Pierce radio.

Chapter 3: Found in the room with pairs of green pipes to the left and right and pallets stacked up along the walls. Jump on the green pallet jack to get atop the right pipes. Enter the part of the wall that is shrouded in shadow. The pallets will not be present there, leaving a cranny behind the pipes. In this cranny is an egg covered in pastel pink, yellow and white stripes. Though it doesn't glow, it stands out completely in the darkness.

Chapter 5: Found in the last hallway of the level, the one leading to the elevator. Use the Dream Soda vending machines as steps to reach the overhead pipes. Once on the pipes, the player can reach the egg, further overhead and situated over the hallways general center. This egg emits red light through its stripes and, upon being clicked, this light turns green.

Chapter 7: Found in the room with the collapsing floor, that follows the fall from the horizontal orange room. After using the staircase to break the floor, use the abundant amount of objects (floorboards, floor supports, chairs, the staircase) available to reach the hallway. Note that the ascent is significantly high.

Chapter 7: Found in the last room of the looping hallway, though the egg only appears after the player has left the room. Take a dice from the pool room and use it to reach the overhead doorway. Next to the recycling box, there will be a plain, pale blue egg.

Chapter 7: Found in the hidden room below the hallway with the shaft. Fall through the shaft and land on a green pipe. The pipe is connected to the hidden room which is empty apart from the egg sitting in the top-left corner. Its pattern is abstract, made up of yellows, reds and blues.

Chapter 8: Found in the room with a Pierce radio in its center and walls being buildings covered in windows. Buildings will be black or white depending on which of two doors the player enters from the previous room. To find the easter egg, the player must fit through a gap between the buildings (on the side holding the room's entry) and circle around the area. Leaning against the back of a building will be a red easter egg with a smiley face. Taking this egg into the nearby star room will make it glow much more intensely than it did before.

Blueprints
Blueprints are blue pieces of paper hidden throughout all levels of the game (excluding Chapter 9). You can click on blank sheets to write their blueprint.

All collected blueprints will appear on a bulletin board in the hallway that immediately follows the bedroom at the start of each level. Everything to the right of the hallway is blocked off by a scissor gate, making the bulletin board unapproachable but still visible.

Locations
Show/Hide Locations (SPOILER) Writing on all 15 blueprints grants the secret achievement "Feeling Blue".

Chapter 1: Found in last room across the hole you fall into, on the backside of the sky painting.

Chapter 2: Found in the outer room encompassing the looping red room (where an easter egg is also found). After going over the red/inner rooms walls using an exit sign, a blueprint is plastered on the backside of the red/inner rooms walls.

Chapter 2: Found in the room above the moon room. Using the object/s on the moon (the can, cheese, building block and/or doorway), the player can reach the opening in the skylight. The blueprint is on the floor, on the opposite end of the room.

Chapter 3: Found in the room with sliding dice and vents. Blueprint lies on the on top of the left, sliding vent. The easiest way it can be reached is by standing on the dice nearest to the vent while raising it.

Chapter 3: Found in the room following the fall from the green shaft, in which the player emerges from within a dice. In the previous room, take a piece of the dice that explodes into smaller cubes and continue holding it while falling down the shaft. Use the piece as a step to get onto the ledge. The blueprint lies on the floor, beside the hallways dead-end.

Chapter 4: Found in the hidden room next to the generator room. Walk along the leftmost wooden beam beside the generator and land atop the left shelf of boxes. Slightly to the left, at the back of the room, the blueprint lies on the floor.

Chapter 6: Found in the room inside the window. To the left of the door to the next room, on the pile of boxes, lies the blueprint.

Chapter 6: Found in the latter half of the locker room. To reach it, take the inflatable castle from the next room and use it as a step to reach the closest ledge (the ledge adjoining the vertical duplicate of the locker room). The blueprint lies on the right.

Chapter 6: Found in the furniture-filled room, following the empty, key-hole room. Using the two doorways/portals, adjust your size to be relatively in proportion to the furniture room. The blueprint lies on top of the punch clock, near the white door.

Chapter 7: Found in the pool room that resembles a short staircase. The blueprint is on top of the orange scaffolding, to the rooms right. It can be reached using the two dice as steps.

Chapter 7: Found in the orange room that is below the shaft. After falling, go down the hallway that is opposite the rooms exit. The blueprint lies on the floor, at the hallways dead-end.

Chapter 7: Found in the room with the illusion of infinite lampposts. Investigate the walls until the bedroom appears in the rooms center. Walk along one of the wooden beams that hold up the bedroom onto the roof. The blueprint lies there.

Chapter 8: Found in the area with the disjointed work office. Walk along one of the wooden beams that hold up the office, using an electric box as a step, to get onto the roof. The blueprint lies there.

Chapter 8: Found in the hallway with a reflective, black path and four black windows along its sides. Circle behind the door you entered from. The blueprint is on the floor, near the doors panel.

Chapter 8: Found in the area full of snow-like structures (some in the shape of giant chess pieces) and large water dispensers. To the right of the door you entered, climb over the nearest white mound. The blueprint lies behind it.

Chess Pieces
There are a few glowing red or blue chess pieces hidden. If you click on them, they will emit bright rays of light before disappearing.

Locations
Show/Hide Locations (SPOILER) Chapter 1: Found in the room with a boarded-up door. The chess piece sits on the ledge of the cream-colored walls; in the top, right corner of the room. The planks and/or dice can be used as steps or ramps to reach it. The piece is a blue pawn.

Chapter 2: Found in the room with the pink wall panel and the staircase with the yellow railing. Using the checkered cube and/or the exit door, the chess piece on top of the pink wall panel can be reached. This piece is a red rook.

Chapter 2: Found in the room with the giant, cyan king piece. Once aligned and able to be interacted with, the checkered cube and the king piece can be used as steps to get on top of the ventilation ducts. Where the vents meet the wall, nearest to the exit, there is the blue knight.

Chapter 3: Found in the room with the dice that splits into halves. The two halves can be used as stairs to reach the ventilation duct opening. Inside it is the red king.

Chapter 3: Found in the room following the space underneath the floorboards, where the rooms entry is through a vent. Many items are available to use as steps (including the Dream Soda machine) to reach this chess piece, situated on top of the overhanging air conditioner. This piece is a red queen.

Chapter 4: Found in the cardboard maze. Use the exit sign as a step to get on top of the maze walls and use it again to step even higher. On top of a line of boxes lies the blue pawn. The sign doesn't need to be used as a light source because all chess pieces already glow.

Chapter 4: Found in the hidden room behind the IDEA generator room. Cans of beans from the cafeteria can be used as steps to reach the chess piece. Take one or more to the right half of the hidden room, accessed by walking along the rightmost beam beside the generator (take care to land on the right shelf of boxes, not the floor). The blue pawn is outside the bottom right window so use the shelf and the can/s to reach it.

Chapter 5: Found in the room with the sky panel in front of its entrance. Use the duplicating digital clocks in the next room to build a tower up to the overhanging ventilation ducts. The blue pawn on the vents is large and hard not to spot.

Chapter 5: Found in the hallway connecting the duplicating red apple and the duplicating sign rooms. Use the tin barrel and the light above the hallways exit as steps to reach the overhanging pipes. Walk along the pipe to find the red knight.

Chapter 6: Found in the room after the room where you use the fan to blow off the Jenga blocks, you can grab one of the windows. If you can get it big enough you can walk inside the window. On top of the doorway, there's a blue pawn.

Chapter 7: Found in the horizontal hallway in the room where the door falls off its hinges. The door must be used as a ramp to reach the horizontal hallway entrance. Once inside, the red pawn can be found through a window situated on the floor. It can be interacted with despite the glass barrier.

Chapter 7: Found in the hallway following the room where the yellow queen flattens after being interacted with. To reach the chess piece, use the table and the knight (from the previous room) to get atop the pipe. The knight, again, must be used to step onto the overhanging light fixture. Now the blue queen, above the light fixture, can be collected.

Chapter 8: Found in the very first room of this chapter, with the bed and acoustic foam on the walls. Enter the model room and walk through the hallway at least once (to establish the teleportation between doorways). Decrease the model rooms size and fit it inside the slot of the Dream Soda vending machine. Now the hallway leads into the slot where the blue rook is upside down, plastered to the slots roof. Take care not to take the model room through the whole hallway as this triggers an event that makes the Dream Soda machine no longer accessible.

Chapter 8: Found in the first room of this chapter (same as above). Place the same model room back on the table, taking care it's approx. the same size as the other two models. After exiting the hallway, the player is now small enough to enter the rightmost model, labelled "Jungles' Bistro", through a door on its back. To the left of the stage there is a bar. The blue pawn is sitting among the cans lined up on the bar shelf.

Chapter 8: Found in the room with the snowy atmosphere, full of giant water dispensers and snow-like chess pieces. Take the two king pieces from the next room and use them as steps to get atop the left precipice. Go behind the water dispenser holding the rooms entrance and continue following the path. The very tip of the red chess piece is imprinted on the side of the water dispenser. To complete the piece, and therefore collect the red pawn, align it with the remaining parts on a precipice (the mechanic primarily present in Chapter 2). This area can also be accessed using an elevator glitch point near the child's drawing.

Hidden Achievement
Show/Hide Information (SPOILER) Interacting with all 15 pieces grants the secret achievement "Chess Master". Once you get all the chess pieces, you can click on the monitor at the start of any level and click on it. It takes you to a room with a chessboard. Move the blue rook, and take the red pawn off of the board to put the red player into checkmate. This grants the player the Kasparov hidden achievement.

Constellation Room
These rooms are hidden areas. They're big rooms with lots of stars and at least 1 constellation of an object. If you line up the constellation and click on it, it will disappear.

Locations
Show/Hide Locations (SPOILER) Interacting will all 7 constellations will grant the secret achievement "Stars Align".

Chapter 2: Found in the room following the pink room with ledges to the left and right. Go under the staircase with the yellow railing and continue into the shadows, into the pink star room. The constellation is of a table.

Chapter 3: Found in the room with pairs of green pipes to the left and right and pallets lined up against the walls. The hall to the star room is in the shadow, immediately right of the door the player enters from. This leads to the blue star room in which is the constellation of a mug.

Chapter 4: Found in the main part of the work office, where the Pierce radio is. To the right of the room is a line of three filing cabinets. In the shadow of the right-most cabinet is the hall to the green star room. The constellation is of a cheese wheel.

Chapter 5: Found in the sinuous hallway with the cloud panel in front of the rooms entry. In the last section of the hallway there is a Dream Soda vending machine. The hall to the purple star room is situated in the machine's shadow, cast to the left. The constellation is of a Dream Soda machine.

Chapter 6: Found in the relaxation room/the room projecting a short, looping video of clouds against a wall. Commercial double doors lead to the rooms exit, with the shadow of the right door leading to the star room hall. This star room is blue (the same shade as the one in Chapter 2) and holds the constellation of a chair.

Chapter 7: Found in the white, simulation room that replaces the orange room in reaction to the player interacting with the dice. On the floor there is a path of screens emitting white light. Two panels appear behind the player, one holding a doorway and the other lying on the floor. Go beneath the floor, through a gap in the white screens, where the two panels intersect. Continue along the short, white hall and into the black hall. This leads to the blue (same shade as Chapter 6 and 2) star room which contains the constellation of a spotlight.

Chapter 8: Found in the snow-like room full of giant chess pieces and water dispensers. Right of the white pawn there is a cranny between the snow mounds and the precipice. The blocky exterior of the black hall sticks out from a mound and into the cranny. That hall leads to the grey/white star room that holds the constellation of a keyboard.

Miscellaneous
Other secrets which do not fall into any category. Show/Hide Information (SPOILER)
 * 1) 6-year-old child's drawing in one of the last areas. With a click, it changes from a picture to a page with a drawing, and the spelling says Superliminle. Lovely easter egg, is this done by the child of one of the game designers? (Developer's commentary stated that a six year old fan named Scout (Who notably was a fan for his 'lifetime'), presented the drawing to the developers at a PAX conference, where they had a playable demo. Scout played the demo, and was so excited by it he made the drawing and returned to the conference to present it to the developers the next day. This is their first piece of fan art, and they decided to immortalize it in the game.)
 * 2) Chapter 6: Behind the door that resizes you after you passed through the door with the help of the jump castle is a piano which you can play.
 * 3) Chapter 7: After you fell towards the red pawn walk into the dark area. You can find a TV and some cheese.

Secret Ending
Show/Hide Information (SPOILER) There is a secret dog ending obtainable in Chapter 4. After using the generator to turn the lights in the rooms back on, the player can look back to see a chess piece lean over from behind a door. Approaching it causes the piece to move back and vanish. Going back through the chapter, the piece will continue to appear and vanish until returning to the room with the large pit. The piece will then fall down. If the player chooses to follow it down, they'll find themselves in a room with a doorway and a talking paper bag. Leaving the room takes the player to a repeating hallway bend. Interacting with a radio opens a door that leads into a room with a large machine and a chess piece in a chair. A few seconds later, the game will end. The credits will be accompanied by pictures of dogs.

This ending references the Silent Hill games. The talking paper bag and repeating hallway resemble similar elements from the Silent Hills P.T. demo. The room with the machine and the special credit sequence match the secret dog ending of Silent Hill 2.
