Valve has confirmed that Portal 2 has surpassed 4 million sales since release.
The new was released by Valves David Sawyer in an interview with Neogamr, he also went on to speak about the new map editor DLC coming to Portal 2;
“The Puzzle Maker lets people try their hand at creating puzzles while also letting them discover, share, and easily play what they and other Portal 2 players are coming up with,” he later said.
“So the editor needed to let anyone pick it up and not just use it, but enjoy the process of using it. We think people will have fun with the Puzzle Maker even if they never share their work with anyone else.”
The new content, titled‘Perpetual Testing Initiative’, was released for PC players of Portal 2 but no details have been released regarding a console version as of yet.
