Released barely two days ago, Portal 2′s latest DLC offering, the Perpetual Testing Initiative has turned out to be a pretty massive success, as heralded by a press release from Valve in which they announced some of the PeTI service’s early statistics. Apparently, over 35,000 custom puzzle levels have already been created and published over the Steam Workshop. In total, the Portal 2 playerbase have already consumed over 1.3 million test chamber downloads.
In celebration, Valve is holding a Weekend Workshop sale on the Steam Store, during which Portal 2 will remain at its Midweek Madness discount of 66% off (about 6 dollars/5 euros), Elder Scrolls 5: Skyrim will be 33% off, and within Team Fortress 2′s in-game Mann Co Store, many of the officially released, community-created Steam Workshop items will be available for 50% off their regular price. Now that’s science for you. Quick, go buy things!
And if you haven’t had enough science within the PeTI, then allow me to provide you with some of my recommendations: CaretCaret’s “12 Angry Tests” series, which contains some of the greatest level design, puzzle gameplay and bizarre humor I have ever experienced; Jaxe’s excellent “Decay” mini-series, sporting some incredible level design, built for intermediate to skilled Portal players; Motanum’s A La Tag series, with unique and innovatie gameplay strongly focused on gel gameplay; and the Podcast 17 Community Chamber collection, encompassing all puzzle levels created by my brothers in arms and colleagues: the Podcast 17 community members.
