Valve kicked off a new Portal 2 trailer series today, with the first of four "investment opportunity" videos coming before launch. This edition features panels, the flexible wall, floor, and ceiling construction units that can change the layout of a room with ease.

With Portal 2's release a few weeks away, Valve opted to pull back the curtain on on the game's single-player experience during a recent preview at PAX East 2011.

Our coverage of that preview outlined some of the gags heard within the first ten minutes of gameplay, along with a smattering of story from later in the game (if you don't want to know a thing about the game, you may want to avoid reading it). Read more »

A sure sign that Valve is set to launch a new title is the release of a television commercial for the product in question. Luckily for gamers eagerly anticipating Portal 2, Valve has just released a TV spot for the upcoming title.

Like all great mornings, waking up in the new living quarters at Aperture Laboratories begins with rigorous exercise. Look up, look down, and jump. Mandatory fitness and wellness exercise: passed with flying colors. Apparently fitness isn't as important as they let on at Aperture.

Even when it attempts to teach you the most basic mechanics of a first-person title, Portal 2 applies a thick layer of slapstick. Read more »

[Update 13:30] Portal 2 won't support the PlayStation Move after all. Chet Faliszek replied to Shacknews, calling it a "lost in translation" error and saying Valve is "not supporting the Move controller." Shacknews regrets the error.

If you disagree with buying chocolates, flowers or diamonds to give as Valentine's Day gifts, you'll be delighted to hear that Apeture Science has produced serious scientific research supporting your beliefs. Apparently, the perfect gift is pre-ordering a copy of Portal 2 ahead of its April 20 release.

When we learned that the PlayStation 3 version of Portal 2 would be getting some exclusive Steam features, some Xbox 360 owners may have felt nervous that their version would get the short shrift. Not so, says Valve.

CVG interviewed Valve writer Chet Faliszek, who said the two games would perform exactly the same. "If you bought the PS3 and Xbox 360 versions and put them side by side you can see they're identical games," he said. "The actual content is the same too, across all platforms." Read more »

Batman: Arkham City: Back when Rocksteady released Batman: Arkham Asylum, it didn't take long for perception to shift from "Oh great, another superhero game," to "Best superhero game, ever!!!" And rightfully so, largely due to the game's excellent presentation and core fighting and sleuthing mechanics that managed to make you feel like the Batman himself. Read more »

Unlike its predecessor, Portal 2 will feature user-made levels on all platforms. In an interview with NowGamer, Valve's Chet Faliszek confirmed that PC-made mods will be available on the Xbox 360 and PlayStation 3.

"The mod tools have to stay on the PC side just because there's a bunch of depedencies that require the Windows platform," he said. "But the content that comes out is agnostic, and so we will be seeing that on all the platforms. Depending on the platform you're on I should say, will depend on how we're delivering it."

After announcing in June 2010 that the PlayStation 3 edition of Portal 2 would support Steamworks, developer Valve today revealed exactly what that will entail--it's jolly nice.

Portal 2 on PS3 will support cross-platform multiplayer and chat with the PC and Mac releases, plus cloud-based saved game storage. As if that weren't exciting enough, you'll also get a free SteamPlay version of the game for PC and Mac. Read more »
