Think E3 is easy?
Watch here on E3 week and see how much exercise I do.
Sound intriguing? It gets better. The Perpetual Testing Initiative is a level editor for the best-selling puzzler, allowing gamers to create, share and play their own Portal 2 creations.
The Initiative can even be used from within the game, thanks to the simple puzzle maker which can be used to form mind-bending brain-twisters.
Once created, you'll be able to publish your maps directly to the Steam Workshop so that other people can check 'em out - by browsing, playing, and voting for their favourites. "Selected puzzles" will even be automatically downloaded and installed inside the game, too - giving gamers a taste of what else is out there.
I like video games, fishing, Depeche Mode, long walks on the beach, writing discussion papers and cups of tea. Not necessarily in that order.
