Valve Holds Steam Sale to Celebrate User-made Portal 2 Maps
The overwhelming success of the Portal 2 Perpetual Testing Initiative has caused Valve to hold a Steam sale.
Even though the Portal 2 Perpetual Testing Initiative DLC only launched Tuesday, there's been an overwhelming amount of user-generated maps developed for the game. In celebration of the creation of over 35,000 maps, Valve is holding a mega-Steam sale.
As a part of the Weekend Workshop Special, Portal 2, Skyrim, and Team Fortress 2 workshop items are all on discount. The sale will last until Monday, May 14th.
