Portal 2 getting in-game editor

In Portal 2, players were made to complete a series of devious and deadly tests constructed by the sadistic GLaDOS. Players will soon be able to put themselves in the AI antagonist's metaphorical shoes, as developer Valve today announced that it is working on an in-game editor that will let users create and share their own single-player and cooperative mode test chambers. The update is set for release early next year.

The editor will be the second add-on for Portal, following up on the Peer Review update released earlier this month. That addition continued the cooperative adventures of multiplayer characters P-Body and Atlas and featured a challenge mode playable both in single-player and co-op, as well as leaderboard support. The Peer Review pack was released for free on the Xbox 360, PlayStation 3, and PC. Valve did not specify a cost or platforms for the in-game editor update and had not responded to GameSpot's request for clarification as of press time.

Portal 2--which has shipped 2 million units--is the continuation of the 2007 Orange Box pack-in Portal. The single-player portion of the new title continues the travails of human lab rat Chell, who in the original game used a portal gun to create interdimensional openings on ceilings, walls, and floors in an effort to escape the Aperture Science labs and thwart the diabolical GLaDOS.
