Valve announced today that Portal 2's in-game puzzle maker will be called "Perpetual Testing Initiative," and will be available free on May 8 for PC and Mac. The DLC will be capable of publishing puzzles directly to Steam Workshop, where users can browse, install, and vote on the community's creations.
Plans for the puzzle creator were announced last year, and we confirmed that it was in beta at GDC earlier this year. According to Chet Faliszek, Left 4 Dead 2 is next in line for the Steam Workshop treatment.
“You'll see the Steam Workshop coming from there, then to Left 4 Dead and then we're going to keep using it,” said Faliszek. “It's not just for the modders, it's for the players. It's a super easy way to consume the creations of other people that are just really hard to do otherwise.”
Any plans to flex your physics muscles by making and playing custom Portal 2 puzzles next month?
