Valve's Portal 2 level creator DLC, Perpetual Testing Initiative, is out today, along with an important memo from Aperture Science head honcho Cave Johnson.
Cave Johnson here. Your boss. It's come to my attention that some of you are concerned after receiving my all-staff memo yesterday ("You: Design Test Chambers or You're Fired"). So to put your minds at ease, let me clarify: You are not mentally ill and you did read the memo just fine. It was real. You should be designing test chambers, right now and at all times, or by God I will fire you.
Sounds serious. I'd get to work before the man with the combustible lemons gets any angrier.
Perpetual Testing Initiative is available for Windows and Mac. You can grab it for free on Steam.
