Welcome to Aperture Laboratories

The sequel to 2007's Game of the Year, Portal 2 is a hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science.

Using a highly experimental portal device, you’ll once again face off against a lethally inventive, power-mad A.I. named GLaDOS. And this time you won’t be alone. Meet an expanded cast of characters as you think your way through dangerous, never-before-seen areas of Aperture Laboratories.

Break the laws of spatial physics in ways you never thought possible, with a wider variety of portal puzzles and an expansive story that spans a single player and co-operative game mode.

  • "An astounding accomplishment; part abstract brainteaser, part sci-fi thriller, part black comedy. Imagine being stuck inside a 3D puzzle with a playfully cruel sense of humour."

  • "Sinister, sardonic and stunningly realised… Valve's idiosyncratic extra [is] a work of genius."
