People playing Portal 2 on Xbox 360 and PS3 will have access to all of the user-created levels made on the PC, according to Valve.
Games are more multiplatform than ever these days, but multiplayer is still mainly a local affair. People playing Call of Duty: Black Ops on the PC can't play with people playing it on the Xbox 360, who can't play with people playing it on the PS3. That's about to change, however, with Portal 2 - Valve's inclusion of SteamWorks in the PS3 version means that there's more crossover between multiplatform copies than ever before.
Valve's Chet Faliszek confirmed to NowGamer that while user-created levels must be made on the PC, gamers with an Xbox 360, PS3 or Macintosh PC will be able to play them, too.
"The mod tools have to stay on the PC side just because there's a bunch of dependencies that require the Windows platform," said Faliszek. "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."
Faliszek confirmed that PS3 owners would get the levels as part of SteamWorks updates, but did not mention how the same levels would be delivered to Xbox 360 players.
I'm betting it probably isn't whatever process they had planned to use to update the Xbox 360 version of Team Fortress 2, am I right?
