Portal 2 user-created content will be available on all the platforms supported by the upcoming puzzle/platformer sequel, Valve's Chet Faliszek tells NowGamer, though he adds that this content will be created using Windows. "The mod tools have to stay on the PC side just because there’s a bunch of dependencies that require the Windows platform," Faliszek tells them. "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." Also, VideoGamer.com has word from Faliszek that the game will feature two different end credit sequences, one for single-player and the other for co-op. "Both sets of credits [will feature something special], because we've got two credits," the Valve writer tells them. "So we had to do something twice as amazing." Valve also recently announced Portal 2 will support cross-platform cooperative multiplayer. Thanks VG247.
