Perpetual Testing Initiative level editor due next month.
Updated on
New Portal 2 DLC that lets you create and share your own levels launches on Mac and PC from 8th May, developer Valve has announced.
Titled Perpetual Testing Initiative, it's a free download featuring a "simplified puzzle maker" that lets you publish levels to Steam Workshop where other players can browse, play and vote on them.
Valve hasn't announced a console release for the expansion.
It's the second major DLC release for last year's rapturously-received puzzle sequel, following the Peer Review add-on last October.
