Caring, sharing types rejoice: Valve have released a patch which enables two-controller splitscreen play for Portal 2, making it all the easier to give your co-op buddy a purple nurple when they "accidentally" mis-time the placement of an Excursion Funnel. Again.
All you have to do to activate splitscreen is to press X on the second controller inside the first co-op menu, and then a whole new world of same-screen squabbling is available. We recommend you fuel your newfound fractious fellowship with our recent guide to the top 10 Portal 2 co-op maps .
The patch also fixes a couple of controller support glitches: previously the 'quick ping' button caused the player's movement to stop and it was impossible to exit Robot Enrichment or Create Test Chambers menus using the controller alone. No longer!
