Portal 2 will be receiving a free DLC pack on May 8th, Valve revealed today. The Perpetual Training initiative acts as a simplified puzzle editor, allowing players to create their own challenges and share them via Steam Workshop. We'll naturally be able to download and rate content from other players, providing yet another reason to keep playing Valve's sensational puzzler.
The Perpetual Training Initiative has only been dated for PC and Mac - console versions haven't yet been announced. With Valve making headlines recently due to scurrilous rumours and intruiging speculation, it's great to see some concrete details emerge from the coy studio - and especially when it concerns awesome free stuff.
