Perpetual Testing Initiative
The "Perpetual Testing Initiative" has just been expanded to allow users to design co-op puzzles in Portal 2! This update also introduces a Quick Play feature, giving you quick access to the top-rated maps in various categories.
To aid you in finding a co-op partner, all current owners of Portal 2 will receive a Steam coupon for 75% off a copy of Portal 2, which can be given away to other Steam users. Check your Inventory for details!
