Faliszek noted that "the content that comes out is agnostic, and so we will be seeing that on all platforms". That said, the content delivery method will vary depending on console: "Depending on the platform you're on, I should say, will depend on how we're delivering it," said Chet, hinting that the PlayStation 3 version would take advantage of Valve's Steamworks features.

In an alternative interview with Videogamer, Faliszek has revealed that each of Portal 2's campaign modes (single and co-op) will conclude with a unique ending. "Both sets of credits [will feature something special], because we've got two credits," he explained. "So we had to do something twice as amazing."

Portal 2's due out in April.
