It seems Valve has decided to make 2010 their year. Being one of the slowest moving developers out there they have in the very same month announced Steam for Macs and… as you might have heard today: Valve finally officially announced Portal 2 today. They ran a whole ARG this past week with updates to the game featuring hidden radio transmissions, encoded images and Morse code. Then they went ahead and updated the ending sequence of the game (which you can see after the jump).

Basically it all hints at Chell, the protagonist from the first game, being retrieved by Aperture Science and apparently the old rumors of the sequel having Aperture Science’s dead founder as the devious AI are true. What we do know is that all through this month a lot more information about the game will be released, that it will feature two campaigns, one for single player and one for co-op, that it will feature natural areas besides sterile labs and that the game will most likely be released this October.

That’s right boys, only 7 more months until we’re thinking with portals, once again. That’s already two big announcements for Valve and one must wonder if they’ll be going for the hat-trick… Yes, I’m talking about Episode 3 Valve, not going to be subtle this time. Where is my Episode 3, Gabe Newell?!
