The physics-based puzzle-platformer blends synthetic-sounding compositions on electronic piano, oddly modulated chip music and unusual rhythm patterns to reflect the theme of computers run amok. End credits break-up song "Want You Gone," the spiritual successor to "Still Alive," is written by Jonathan Coulton and performed by GLaDOS voice actor Ellen McLain. "Cara Mia Addio," depicting a chorus of singing turrets, capitalizes on McLain's background as an opera singer.
Portal Companion Collection for Nintendo Switch bundles Portal with the Portal 2 single-player campaign and full co-operative game mode. Valve's physics-based puzzle compilation was developed in collaboration with Nvidia Lightspeed Studios.

Portal 2 Soundtrack: Songs To Test By (4CD SET) ships from Blixt Merchandise, published by Ipecac Music.

The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.
