Unfortunately translation errors meant we all got the wrong end of the stick, and that Portal 2 does not actually support Sony's motion controller. But why not? Eurogamer went to Valve’s Chet Faliszek to find out.

“On the PC version we have the Hydra controller,” he said, “those guys actually sit in our office. They’ve been working in our office for nine months, a year. So it’s not something we’d trivialize and say, ‘oh well, let’s just toss this in, it doesn’t need any thought or anything special.’ They’ve been working in that way for that. We think it deserves that kind of respect if we’re going to do it.

“We’ve always looked at Portal 2 as being the controllers we have going in and then the Hyrda. We designed for those things.”

Ok. So no PlayStation Move support right now, but what about in the future?

“Who knows?,” he replied. “I’m not sure it would make the game better. Obviously there are a bunch of games the Kinect and the Move absolutely made better and are for. But for this, where we had started from day one not thinking about that, it would not.

“The Hydra stuff, those guys have invented new puzzles to make their thing make sense. They’ve done the work to make it fit in and not be just this light touch on the top.”

Portal 2's out at the end of April.
