Multiple endings confirmed for Portal 2

Portal 2 will offer two different endings, one for single play and one for co-op play, developer Valve has confirmed.

Speaking to Videogamer, the title's writer Chet Falliszek promised, "Both sets of credits [will feature something special], because we've got two credits."

He went on to explain that finishing the game should be well within reach of most players.

"The cool thing is that we'll make sure that the game doesn't get too difficult. It's more complex, but it's never so difficult that you can't solve it. You'll get to the endings. We'd hate to think that people would only watch the endings on YouTube."

If Valve wants to top the original's conclusion it'll have to pull something seriously special out of the bag. Portal's memorable end credits have now been viewed around five million times on YouTube, Falliszek noticed.

Jonathan Coulton, the composer of Still Alive, the infectious ditty that played the first game out, recently confirmed that he has written a new tune for the sequel, though he wouldn't confirm where in the game it will appear.

In a separate interview with NowGamer, Falliszek also revealed that all platforms would be getting user-generated content, including the often shut-out Xbox 360.

"The mod tools have to stay on the PC side just because there's a bunch of dependencies that require the Windows platform," he explained.

"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."

"There's just a lot of value in engaging the community because they're smart, they're thinking of really cool things and we want to be able to have everyone share that."

Not long to wait until you can check all this stuff out. The much-anticipated sequel to Valve's 2007 first person puzzler arrives for PC, PlayStation 3 and Xbox 360 on 22nd April.
