It seems Dota 2 and Team Fortress 2 have launched Merchandise Workshops, where the community can submit, vote on and sell their own non-virtual, actually real t-shirts and posters. And so far, the response from their communities has been overwhelmingly positive. So we thought: What if we applied that same idea, but to a good game, with a smarter, more attractive community? Introducing the Portal Merchandise Workshop, where you can heroes can bravely design their own Portal universe concepts.

"But what if my ideas are bad and I don't have any talent?" you ask. Don't sweat it, you're still covered.

Are you sitting down? If not, you should sit down. Okay, are you sitting down now? Because you should probably actually be lying down for this: As of right this moment, we are giving all current owners of Portal 2 a 75% off Portal 2 coupon. If you're standing back up, dusting yourself off and wondering why you'd want another copy of a game you already own, lie back down real quick because here's the lie-down part: We just added co-op to the Perpetual Testing Initiative.

That's right: Puzzle creators can now design and publish co-op maps, which puzzle players can now greedily consume. Well, as long as they have a co-op partner. Which the 75% off coupon should help them (i.e.: you) find. We've also added a "Quick Play" feature that creates never-ending, auto-generated playlists of the top-rated maps in a variety of categories. It has literally never been easier to figuratively jump in and literally play some Portal.

Thanks to an anonymous tech at NASA, Wheatley is actually going to actual space. This Friday at 10:06 EST, the Japanese HTV-3 resupply craft to the ISS will launch the above panel into space. Though mankind will surely regret giving Wheatley a celestial perch to plot his next move, we here at Valve are mostly just impressed with NASA's bold, unprecedented resupply craft numbering scheme. And please note that when we mentioned an "anonymous tech at NASA" we weren't kidding: NASA in no way officially endorses secretly laser-engraving characters from Portal onto their spacecraft. Believe it or not, they don't even officially endorse Portal 2, despite the fact that it's a really excellent game.

You can watch the launch here beginning at 9:15 EST / 6:15 PST.
