Quick Play mode, co-op puzzle making added to Portal 2

As if regular co-op and custom puzzles for Portal 2 wasn't enough, Valve has gone ahead and smashed the two together, so now you can create Portal 2 puzzles with a friend or loved one on PC. If said friend or loved one doesn't have a copy, 75% off coupons have been added to all accounts for this very purpose.

A Quick Play feature has been added, too, which lets you play through an endless list of the top maps in a bunch of different categories. So while there's no GLaDoS around to harass you, it should feel almost like playing Portal 3.
