Valve today announced a free addition to the Portal 2 in-game puzzle maker that allows users to create co-op test chambers.
“Since its release on the PC and Mac in May, 2012, community map makers have used the Steam Workshop and Portal 2′s in-game editor – called the Perpetual Testing Initiative – to create and share more than 170,000 single-player test chambers. With this update, the community will for the first time be able to design puzzles that require two players working cooperatively to solve.
This update also introduces a “Quick Play” feature, which allows players to quickly access the top-rated maps in various categories.
To help players find a co-op partner, Valve is giving every current owner of Portal 2 a Steam coupon for 75% off a copy of Portal 2, which can be given away to other Steam users.
Portal 2 holds a Metacritic score of 95% and has been awarded numerous Game of Year awards. It features expansive single and cooperative multiplayer game modes.
