Several of the announcements from Cave Johnson can be pieced together to create an overall storyline taking place during testing. In-game, the Test Subjects are represented by Bendies. Test Subjects from Earth One are then sent there to test the chambers. Instead of having Test Chambers built in our own dimension (known as Earth One), the plans are sent to versions of Aperture Science in other dimensions within the multiverse, and these alternate Apertures will then build the Test Chambers. In order to do so, he establishes the Extra-Earth Outsourcing Initiative. In the new storyline of the Perpetual Testing Initiative (which is possibly set in 1988, according to its trailer), Cave Johnson wants to lessen Aperture's spending, to avoid bankruptcy. It can be replayed at any time from Portal 2's in-game Extras menu.

I expect to spend many more hours in test chambers… for science.PeTI was first officially introduced in an informational video narrated by Cave Johnson, officially released on April 27, 2012, and featured as an introduction in the level editor itself. The quality wil vary considerably, but of the dozen that I have played so far, half have been satisfyingly head-scratching and rewarding.

Already though Steam claim there are over 4,000 maps in PeTI, with undoubtably many more to come. Portal 2 is one of my favourite games, but it’s fair criticism to say that the puzzles weren’t as challenging or numerous as they could have been. By all means subscribe to my workshop, as I’ll probably create a few more puzzles using different elements. I’d love to get some feedback on the design, either here or on the Steam page. I called my first level Bouncy Bridge (a big hint in the title there). All the ingredients that make up a typical Portal level are there to place and combine in whatever clever combinations you can dream up. Portal 2 has been reduced to £5.09 on Steam until May 11. IGN has a great video tutorial that’ll get you started. As the video above suggests, the PeTI is an easy-to-use level editor and a place to share the levels you create and play, rate and comment on levels by others. Yesterday Valve updated Portal 2 to add the Perpetual Testing Initiative.
