A Crusher in Portal 2.

The Crusher is a hazard element present in several testing environments, introduced in Portal 2. A player who makes contact with a crusher will be forced to the nearest hard surface and will be killed instantly. Crushers appear as large grey panels with many large, steel spikes firmly attached.

Crushers become more frequent during the final parts of the game (particularly in Chapter 9: "The Part Where He Kills You"), and also appear frequently in co-op mode.

Function

Any object, including the player, will be perforated instantly upon contact with a crusher. When crushing, a loud crunching noise is made to warn the player of its danger, and to indicate to move out of the way quickly.

In co-op mode, if the player comes in contact with a crusher while floating in an Excursion Funnel, the damage caused will be periodic until the player moves away or dies.

Trivia

• Crushers were intended to appear in the original Portal but were removed at early stages of game development due to complexity they add to test chambers.
• However they do appear in Portal: Flash Version, a 2D flash game released before Portal itself, and in Portal: The Flash Version MapPack.
