Let’s take a look at the official press release, straight from Valve:
Valve, creators of best-selling game franchises (such as Half-Life and Counter-Strike) and leading technologies (such as Steam and Source), today announced the free Portal 2 DLC titled “Perpetual Testing Initiative” will be available for the PC and Mac on May 8th.
The “Perpetual Testing Initiative” allows players to easily create, share, and play Portal 2 puzzles. The Initiative comes with a simplified puzzle maker that allows that creation of mind-bending puzzles without ever leaving the game. The puzzle maker can directly publish maps to the Steam Workshop where users can browse, vote on, and select to play them. Selected puzzles will automatically be downloaded and installed inside Portal 2.
Sounds pretty neat! Unfortunately, judging by the sound of this, the PTI will be a PC-Mac exclusive feature, at least for the time being. That’s a shame, but hopefully console gamers will see it some time soon – while redesigning the Puzzle Creator to support gamepad controls would be challenging, I’m sure the PTI would be a perfect fit for the console experience. Similarly, the Initiative will not include support for co-op maps at launch, and that’s a shame as well.
I’m also disappointed regarding the lack of any new Valve content in this DLC pack - last year, Peer Review’s awful ”Art Therapy” co-op DLC course left me with a really, really bad taste in my mouth, and so, I really wanted to see a new singleplayer mini-campaign. Of course, Valve might not be done with post-release support for P2 just yet, so let’s keep our fingers crossed for more substantial future DLC releases.
Remember that GameTrailers TV will be releasing the reveal trailer (featuring Cave Johnson himself) for the Perpetual Testing Initiative DLC in about 11 hours – we’ll let you guys know when it comes out. We might also be directly covering the DLC’s closed preview version, which will become available this Monday, so stay tuned!
