Portal 2‘s second DLC–titled “Perpetual Testing Initiative”–is coming to the PC and Mac for free on May 8. The DLC is basically a puzzle editor that allows you to make your own Portal 2 levels and share them through the Steam Workshop. Console gamers are out of luck for now, though new copies of the PS3 version did come with a free download code for Portal 2 on PC and Mac anyway. Even if the DLC does come to the PS3 version, it’s unlikely to ever be released on Xbox 360, as that version of the game doesn’t support the Steam service.
-Nick’s take: Portal 2 is a fantastic game, now made even better by a free puzzle editor. Thanks Valve!
