An all-new co-op adventure starring Atlas, P-Body and GLaDOS, the free DLC "Peer Review" takes place an unknown period of time after the events of Portal 2. You and your co-op science partner are once again awoken and assembled for a dangerous new mission. Did we say "dangerous"? We meant routine. Everything's fine. That slight note of terror you're hearing in GLaDOS's voice is probably just an audio calibration error. Anyway, on with your suicide mission. And when we say "suicide mission" we mean it would be suicide not to take this mission. Because it's so safe. Everything's fine.

"Peer Review" is being rolled out across all regions on Steam, Xbox LIVE and PSN as we speak. The free DLC is available to all owners of Portal 2 for download on PS3 and Xbox 360, and will be automatically downloaded via Steam on PC and Mac.

And if you're not an owner of Portal 2, don't sweat it, we've made it easier to become one: To celebrate the release of the free DLC, Portal 2 is on sale for 50% off on Steam through Thursday.

We were chatting with Portal 2 Lead Composer Mike Morasky the other day, and he casually mentioned that Songs to Test By Volumes One and Two have, to date, been downloaded close to two million times. We said that was nice, even though it didn't have anything to do with what we'd been talking about (bass fishing), and we asked him if we could go back to talking about that. Mike said okay. Then he asked us if we'd ever been bass fishing a million times, because if we had that would mean we'd fished for bass half as much as the Portal 2 soundtrack's been downloaded. This is why we don't talk to Mike.

Anyway, the third and final volume of Songs to Test by is now available to download. We're not sure how many times the last two volumes were downloaded--five times, maybe, or six, if we had to guess--but according to the number currently being sky-written by a plane outside Valve's windows it was actually two million. Make it two million and one now.

Oh yeah, by the way, before we forget, the first Portal 2 DLC, "Peer Review" will be out next Wednesday. For free.

The Summer Mapping Initiative has been completed and thinkingwithportals.com has selected the winners. There were 280 entries that took the 13 Judges over 140 hours to play.

Patent Pending was the overall winner with Infinifling grabbing second place. The voting was so close, we added an honorable mention for Edifice.

Since we all know that the appreciation of your fellow man is not a real prize, they will all also be receiving the following:

Jinx Portal 2 Gear

Gels and a Shirt from Think Geek.

Gear from Glitch

More Shirts than you can wear in a week, enough Posters to wallpaper your cell, and more from Valve.

Not pictured because we haven't even released them yet - the winners will also receive a Wheatley Laboratories Glow in the Dark T-shirt and the super cool 70s Portal 2 poster signed by the entire team.

Right now we know what you're thinking, "I'm an idiot. That's a ton of cool stuff! I should have entered that contest!"

First. You're right. Second, don't worry you still have a chance. This prize package pales in comparison to what Valve and The National have for the winners of the Portal 2 Music Video contest.
