The magical Portal 2 DLC that was once promised for mid-September is hitting us a bit later, but not by much. Valve announced Friday that Portal 2‘s first set of downloadable content will finally be releasing this Wednesday, October 5th. Oh and it will be completely free. Even on the Xbox. I’ve no idea how Valve pulled that particular magic trick off, but kudos to them. The DLC will include new test chambers, single and multiplayer challenge modes, as well as leaderboards to cover it all. Eh, but who cares about all those minute details, here’s the gist of it all: you will be able to play new content in Portal 2 this Wednesday. So grab a buddy, and get ready for some science.
