"Had a bit of a brain wave. There I was, smashing some steel plates together, and I thought, 'yes, it's deadly. But what's missing? What's missing?' And I thought lots of sharp bits welded onto the flat bits."

The Aperture Science Crusher, referred to as a mashy spike plate by Wheatley, is a variation of the Aperture Science Panel with extensive redesigns, with the sole purpose of killing Test Subjects through impaling.

The Crushers are a rare testing element and a defective product smasher near the entrance to the Incinerator Room of the Aperture Science Enrichment Center in Portal 2.


The Crushers were first spotted in the single-player campaign chapter The Courtesy Call, during the fall from Central AI Chamber to the Incinerator Room after GLaDOS was reawakened.

It is then formally introduced by Wheatley, after he assumes power in the Enrichment Center, in a death trap against Chell and GLaDOS, after he decided that the common Panels were not as deadly and effective in killing her, despite that it could flip over Chell to make her fall to her death. After the duo escaped the first death trap, Wheatley repeatedly attempts to use the Crushers to kill her, but fails.

After regaining control over the Enrichment Center, GLaDOS then adapts the Crushers into the Mass and Velocity test course in the cooperative campaign, where ATLAS and P-body have to sacrifice one another in an attempt to disable the Crushers. It is then used for the last time in the Mobility Gels test course, located in the unnamed Co-op Test Shaft. As the title of the course suggests, the bots are to utilize the momentum of speed using the Propulsion Gel to send themselves across several Crushers.

Behind the scenes[edit]

Although it was not originally named, a moving ceiling with spikes was demonstrated in the earliest Portal trailer.

According to Cayle George, a designer for Portal 2, there were to be several levels utilizing Crushers in ways that made the test chambers more dangerous. After showing some of these levels in press demos, Valve got feedback that viewers were getting the impression that Portal 2 was going to be too difficult since players would have to time events such as running or falling through a portal with not getting hit by a deadly crusher. The team decided to save these for the escape, when Wheatley tries to hold the player off.[1]


Although Wheatley claims to invent them, two pairs of Crushers can be seen while Chell was falling down to the Incinerator Room. Also, in the informational video Aperture Investment Opportunity #1: "Panels", CEO Cave Johnson states that Aperture Science sells Crushers.
