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 <i style="font-style: italic;">Portal 2</i>. 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 <i style="font-style: italic;">Portal 2</i> 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 <i style="font-style: italic;">Portal 2</i>, don't sweat it, we've made it easier to become one: To celebrate the release of the free DLC, <i style="font-style: italic;">Portal 2</i> is on sale for <a href="http://store.steampowered.com/app/620/">50% off on Steam</a> 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.

With Aperture-brand turrets, boots, bots and panels flooding the applied science aisle of your local department store, you could forgive the up-and-coming test lab for taking a breather. Judging from their latest press release, though, their laurels remain untouched by backsides. Bolstered by recent breakthroughs in the field of jazz smoothing, Aperture announced today the first of three downloadable aural stimulus packages.

Whether you're a mega-science corporation with decades of test experience, or a young start-up liberating your first test subject from non-testing with a chloroform-soaked rag, Aperture guarantees results. Wake up your test subject, open the chamber door, and press play--let Aperture's patent-pending rhythmic compliance enhancers do the rest.
