Aperture Science Weighted Storage Cube

"The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak. In the event that the Weighted Companion Cube does speak, the Enrichment Center urges you to disregard its advice."

The Aperture Science Weighted Storage Cube, along with the Aperture Science Weighted Companion Cube, is a testing element used in various Testing Tracks of the Enrichment Center.

Overview

 * The Weighted Storage Cube is a device used for solving cube-and-button based puzzles in the various Test Chambers found throughout the Enrichment Center.


 * In Portal and the Single Player campaign of Portal 2, Weighted Storage Cubes are to be placed on a Super Button to allow Test Subjects to advance.


 * In the cooperative campaign of Portal 2, the Weighted Storage Cubes are to be placed on Cube Buttons.


 * Weighted Storage Cubes appear either via an Aperture Science Vital Apparatus Vent or are already in a test chamber.


 * It can be picked up by using the "use" key and can also be taken through portals.


 * The Weighted Storage Cube can also be used as a makeshift weapon against an Aperture Science Sentry Turret by dropping it on the Sentry Gun from a Portal, or as a makeshift shield to block turret fire and energy pellets.


 * Like most objects, the Weighted Storage Cube will disintegrate upon touching an Aperture Science Material Emancipation Grill.


 * In Portal 2, the cubes have a circular blue light on each side, and when left on a button it changes to a yellow light. They are also notably smaller in size than in Portal.


 * The Weighted Companion Cube in Portal 2 bears a resemblance to the standard Cubes, their only difference is that they have a heart on each face of the Cube and emit a pink light.


 * A special type of Storage Cube, the Weighted Companion Cube appears in both Portal and Portal 2. It is identical to the regular Weighted Storage Cube in both games, except that it has a heart where the Aperture Science logo would be. At the end of the Test Chamber 17 in Portal, the player is forced to put it into an Aperture Science Emergency Intelligence Incinerator. Narrative provided by GLaDOS and Doug Rattmann suggests that the Companion Cube is designed to test emotional stress by having subjects develop affection for it before being forced to destroy it.
 * In Portal 2's third chapter Test Chamber 07, GLaDOS reveals that there are warehouses full of Weighted Companion Cubes shortly after disintegrating two of them. She also contradicts her statements from the first game, openly stating that they are sentient. As the Material Emancipation Grill for that chamber is not functioning, Chell can remove the companion cube from that chamber (earning the player the "Preservation of Mass" achievement/trophy), only to have GLaDOS destroy it herself shortly before reaching the elevator.


 * Twentieth century prototypes of the Storage Cubes were seen in the old condemned parts of the Aperture Science Innovators test chambers, where they also served a similar purpose for weighing down buttons. These cubes can react to the Mobility Gels, as well. It is unknown if the early cubes were simple crates with nothing inside, or if they were actually weighed down to help push down and hold in place the early Aperture Science Super Buttons. These cubes also appear to be made of wood, held together by staples. No analogue of the Companion Cubes appear.

Behind the scenes

 * The Weighted Companion Cube was invented because playtesters often failed to realize that the puzzle required you to take the cube with you, so they made it unique and more noticeable, and had GLaDOS put a great deal of emphasis on it in her voiceover.
 * A plush Weighted Companion Cube is available to purchase online at Valve online.
 * Dropping a Weighted Storage Cube (spawned by the console) into the incinerator at the end of Test Chamber 17 will give you the same result as dropping the Companion Cube. This is probably because the Companion Cube is just a re-skinned Storage Cube.
 * If the Companion Cube is dropped into the incinerator at the end of Test Chamber 17, it will re-spawn in the Vital Apparatus Vent at the beginning of the chamber, most likely due to developer oversight, though at that point the player is no longer capable of returning to that spot, so it is a moot point.
 * A Companion Cube prop can be unlocked for Xbox Live avatars by completing the Portal 2 Single Player campaign.
 * The teaser trailer version of GLaDOS' Incinerator Room features the burned Companion Cube.

Trivia

 * The Companion Cube from Portal is implied to have never been completely incinerated during the ending sequence of Portal 2. This is noted by the amount of burns marks it has sustained, also implied from statistics of the Portal Gun which can endure temperatures of up to 4000 kelvin, that subsequent Aperture products are also able to.
 * In Portal 2, when held, the Companion Cube causes the game to play a type of tune or chime specific to it, much like how certain music plays during the activation or use of certain testing elements of functioning Aperture Science technology (eg. Aerial Faith Plate).
