Portal 2 Perpetual Testing Initiative success leads to Workshop sale


Valve's "Perpetual Testing Initiative" has already been yielding results, and they provide evidence for the hypothesis that people still like playing Portal 2. Since the DLC's release on May 8, the company reports that over 35,000 user-created maps have been uploaded, which have been downloaded over 1.3 million times.

To celebrate this successful experiment, Valve has discounted several items on Steam, including, of course, Portal 2, which costs just $6.79 right now! Fellow Steam Workshop title Skyrim is on sale for $40.19, and several Workshop items within Team Fortress 2 can be found for 50 percent off.

Steam Workshop Sale On Now In Celebration

May 10, 2012 -- Valve, creators of best-selling game franchises (such as Half-Life and Counter-Strike) and leading technologies (such as Steam and Source), today announced the early findings of the Portal 2 Perpetual Testing Initiative.

Released just days ago, The "Perpetual Testing Initiative" has already resulted in the creation and publishing of over 35,000 user-created maps, collectively consumed via more than 1.3 million downloads.

To celebrate the launch, Steam is holding a Weekend Workshop Sale offering Portal 2 for 66% off, Elder Scrolls V: Skyrim for 33% off, and many of this year's Team Fortress 2 Workshop Items available for 50% off their regular price.

The Perpetual Testing Initiative allows players to easily create, share, and play Portal 2 puzzles. The Initiative comes with a simplified Puzzle Maker that allows that creation of mind-bending puzzles without ever leaving the game.

The Puzzle Maker directly publishes maps to the Steam Workshop where users may browse, vote on, and select to play them. Selected puzzles are automatically downloaded and installed inside Portal 2.
