This is a sub-page of Superliminal/Version Differences.
This page documents fire alarms, fire extinguishers and blueprints which have been moved, added or removed since the release of the game (see Environmental Differences for the visual changes). Most of these changes were made in version 1.10.2020.7.6.877, as this was the update which added proper tracking of collectables, but there have been a few changes made since.
It's worth noting that this page only covers what the game actually considers to be a collectable as of 1.10.2020.7.6.877. This therefore excludes:
- Literal easter eggs
- The fire alarm and fire extinguisher in the Kasparov room in Whitespace
- The fire alarms in Jungles' Bistro in Whitespace
- The fire alarms and fire extinguishers in Retrospect
Collectables which are described as "removed" have been completely deleted from the game, whereas collectables which are described as "disabled" are still in the game and can be re-enabled with a tool like UnityExplorer.
Mechanics#
Level Select#
1.10.2020.7.6.877 added displays for the collectables as you hover over the levels. The icon for a collectable will appear on all of the levels once you have activated one of them.
Fire Alarms and Extinguishers#
After 1.10.2020.7.6.877, the game now keeps track of the fire alarms and fire extinguishers that you click on in the DrPierceARealDr save file, meaning that they will stay activated even after reloading.
Blueprints#
After 1.10.2020.7.6.877, blueprints need to be clicked before they display their level wireframe. This is tracked in the same way as fire alarms and extinguishers.

Labyrinth Clone Hallway#

Disabled in version 1.10.2020.7.6.877.
Fire Extinguishers#
Added#
Optical Warehouse Wall#

Added in version 1.10.2020.7.6.877. It was in the game before this update, but it wasn't a collectable - it was a different size to the rest of the fire extinguishers and could not be interacted with.
Removed#
Optical Green King Room Entrance#

Disabled in version 1.10.2020.7.6.877.
Blackout Hallway Before Freezer#

Disabled in version 1.10.2020.7.6.877.
Blackout Left Kitchen Area#

Removed in version 1.10.2020.7.6.877. It was previously inaccessible.
Blackout Right Kitchen Area#

Removed in version 1.10.2020.7.6.877. It was previously inaccessible.
Labyrinth Corner of Warehouse#

Disabled in version 1.10.2020.7.6.877.
Labyrinth Out of Bounds Near Warehouse#

Disabled in version 1.10.2020.7.6.877. It was previously inaccessible.
Labyrinth Behind Painting#

Disabled in version 1.10.2020.7.6.877. It was leftover from Dollhouse, but a wall was placed in front of it which meant that it was inaccessible. In the screenshot this wall has been removed and two disabled wall lamps have been enabled, since otherwise the extinguisher is impossible to see (an unedited screenshot can be found here). When it was disabled, "_INACCESSIBLE" was added to the end of its filename.
Labyrinth Near Red Pawn in Unused Area#

Disabled in version 1.10.2020.7.6.877. When the gravity supposedly changes, the player is actually walking through a portal to a different part of the level. Behind this portal there was originally an upright version of the next area which you never actually walk through, since you're teleported to a sideways version of it instead. At the end of this inaccessible upright area was an extinguisher. When it was disabled, "_INACCESSIBLE" was added to the end of its filename.
Labyrinth Above Red Pawn in Unused Area#

Disabled in version 1.10.2020.7.6.877. As with the previous removed extinguisher, this one was behind the portal that makes it look like the gravity changes. However, it was on the other side of it - after you go through the portal to the sideways area, the extinguisher is then above you in a sideways version of the area that you were just in. Again, "_INACESSIBLE" was added to the end of the extinguisher's filename after it was disabled, and yes, it's misspelt like that in-game.
Labyrinth Fall After Red Pawn#

Disabled in version 1.10.2020.7.6.877.
Labyrinth Top of Cube Illusion Room#

Disabled in version 1.10.2020.7.6.877. It was previously inaccessible.
