The latest DLC for Portal 2 finally answers the question fans have been asking since they finished the game: How can I build my own test chambers? This was an especially salient point considering a good part of the story involved levels created before your eyes by either GlaDOS or Wheatley. Well now thanks to Valve you finally get to take a stab at it. Actually, if you were willing to brave the complexity of their Hammer level editor this was already a possibility before, but now it’s as simple as a point, click, and drag.
