After nearly two and half years of the release of Portal 2, I felt it was time to revisit the facilities of Aperture Science. With the release of the Perpetual Testing Initiative, Valve gives people the power to create challenges of their own and not just be a test chamber Guinea Pig.
When you enter the test chamber editor of the game, you’re provided with a starter test chamber and a small toolbox of assets to use in the creation of your level. The construction of the level is very easy, to build your chamber you merely need to select the surface of a panel and pull it in or out. With this, you can have the design of you chamber laid out in no time!
