Portal was a singleplayer game. Portal 2 adds co-op, but did you know it was at one stage also going to add competitive multiplayer?

"Along with co-op, [we had] the idea of sort of a competitive Portal multiplayer," Valve's Erik "Old Man Murray" Wolpaw told 1UP.

"We went down that path, actually, for a little while and had something up and running — the best way to describe it is sort of Speedball meets Portal. You know, a sports analogy. And it quickly became apparent that while it's fun for about two seconds to drop portals under people and things like that, it quickly just devolves into pure chaos. It lost a lot of the stuff that was really entertaining about Portal, which was puzzle-solving. Cooperative puzzle-solving was just a much more rewarding path."

Wolpaw says this game mode, which had you shifting a ball around, was a "hot mess".

Speedball meets Portal was a bad thing? Just goes to show, dreams don't always come true.

Two new all-gameplay videos from Valve show a couple of tools you'll be using in Portal 2, both of which launch you through the air. Some creative use, in conjunction with the portal gun, is required. Isn't it always?

Repulsion gel (above) looks like it works like silly putty in reverse. Instead of it bouncing everywhere, it bounces you (and associated objects).

The Aerial faith plate (at bottom) is a kind of angled trampoline that can get you where you want to go, and get others where they don't want to be.

Portal 2 is coming out next year on PC, PS3, Xbox 360 and Mac, but the videos done tole you that. Twice.

Freshmen at Wabash College in Crawfordsville, Indiana this year will be required to read Gilgamesh, Aristotle's Politics, the poetry of John Donne, Shakespeare's Hamlet, and Valve's Portal.

Michael Abbott, the proprietor of video game blog The Brainy Gamer and a teacher at the small liberal arts college found himself part of a committee last year tasked with creating a new all-college course devoted to "engaging students with fundamental questions of humanity from multiple perspectives and fostering a sense of community." The course would gather together classic and contemporary works across multiple disciplines in order to have students "confront what it means to be human and how we understand ourselves, our relationships, and our world."

Being The Brainy Gamer, Abbott's mind immediately went to gaming, specifically Portal, and even more specifically to a recent essay by Daniel Johnson on Portal and its connections to Erving Goffman's Presentation of Self in Everyday Life.

Abbott merged the ideas together and decided to propose that students read Goffman's work and then play through Portal. Now he only had to get the idea through committee.

I pitched the idea to my colleagues on the committee (decidedly not a collection of gamers), and they agreed to try Portal and read selections from Goffman's book. After plowing through some installation issues ("What does this Steam do? Will it expose me to viruses?"), we enjoyed the first meaningful discussion about a video game I've ever had with a group of colleagues across disciplines. They got it. They made the connections, and they enjoyed the game. Most importantly, they saw how Portal could provoke thoughtful reflection and vigorous conversation on questions germane to the course.

So now Portal will be required "reading" at Wabash College, rolled out slowly as the teachers figure out how to deal with licensing, installation, making sure educators who had never touched a video game knew what they were doing.

Is it too late for me to go back to college?

Oh man. If you were wondering how co-op would work in Valve's upcoming Portal 2, wonder no more. It works a little something like this.

Portal 2 is playable at GamesCom, and while some people are playing it, others are filming it being played, so everyone else can enjoy it!

In case you're wondering, no, that is not the voice of an over-eager booth assistant. It's Wheatley, your AI companion in the game, who is voiced by British radio man, actor and co-creator of The Office and Extras, Stephen Merchant.

He may sound annoying at first, but I'll take annoying if it means there's somebody to talk to in the game that's not a psychopathic AI bent on my destruction. Unless he turns out to also be a psychopathic AI bent on my destruction, in which case, screw you, Wheatley.

We now know how to make a Justin Bieber song sound good: slow it down 800%. But what happens when Portal's Still Alive, that great video game song from Jonathan Coulton, gets the same treatment? Listen.

Gate Online, a South Korean online game Kotaku previously introduced, appears to take its cues from two Valve titles: Portal and Team Fortress 2.

Team Fortress 2 is a well-spring of sorts. Last summer, the game inspired another South Korean developed PC title, H.A.V.E. Online.

The influences for Gate Online are not as blatant as for H.A.V.E. Online, and the game's developers do seem like they are trying to incorporate those influences and push them forward in a somewhat engaging way.

Thanks Joshua for the tip!

While this crossover would make Portal's combat clumsier, you'd imagine on the flipside it'd make running around that empty old castle a breeze. By junkboy, as seen on Bytejacker.

Upcoming online game Gate has players create portals, here called "gates", to warp themselves to different areas in the game world. Hrm, that sounds familiar!

Portal, released in 2007 by U.S. developer Valve, has players solve puzzles by using the portal gun to open up teleports. Below is a screenshot from the game.

According to website 4Gamer.net, Gate is a first-person shooter. However, it actually appears to be a third-person shooter. Gate, unlike Portal, does offer a variety in playable characters and weapons, but still.

The issue here isn't just portals — 2006's Prey had portals before Portal — but namely the color and the shape of them. What's more, in Gate players can make gates, portals, whatever á la Portal.

Last summer, another South Korean developer released PC title H.A.V.E. Online, a game that looked very much like Valve's Team Fortress.

Details about when Gate goes online in South Korea are forthcoming.

It's so simple; all you need is a mirror, some blue paint, and a love for Valve's masterpiece in virtual teleportation.

Suitably, considering this comes from Sweden, the mirror is from IKEA (a Kolja, if you're taking notes), and the rest really is as simple as it looks. Just paint a two-tone blue border around the oval-shaped mirror, stick it on your wall, and you're good to go.

Those requiring the full Portal effect, just buy two mirrors and get some orange paint!
