Free DLC is coming to Portal 2 on May 8th. Valve today announced Perpetual Testing Initiative available for PC and Mac.
Perpetual Testing Initiative allows players to easily create, share,and play Portal 2 puzzles. It comes with a "simplified puzzle maker" that allows players to create puzzles without having to leave the game.
Using this puzzle maker, players can directly publish maps to the Steam Workshop where users will be able to browse, vote on, and select to play them. Once selected, puzzles will automatically be downloaded and installed inside Portal 2.
Valve hasn't yet announced a console release for the expansion.
