Valve, creators of best-selling game franchises (such as Half-Life, Left 4 Dead, Team Fortress, and Counter-Strike) and leading technologies (such as Steam and Source), today announced the second game add-on for the year's highest rated multiplatform game, Portal 2, is in development and targeted for release early next year.
This major update will feature an easy-to-use in-game map editor that will let users design, build and share their own single-player and co-op test chambers with the community, who will be able to view, play and vote on them with a simple click.
Portal 2 was released April 19, and currently holds a Metacritic score of 95%, making it the top-rated multiplatform game of 2011. Its first content update, "Peer Review", came out two weeks ago.
A hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science, Portal 2 features expansive single and cooperative multiplayer game modes.
