Portal 2 "Summer" DLC out on Oct 4th.
 

Obviously free for PC, but the console versions are free too. It's a continuation of the Co-op campaign.
Additionally, part 3 of the official soundtrack is also up. Huh. Valve actually came out with a part3 of something.




There's also this.

"Peer Review", eh? Interesting name.

Oh crap, so now the turrets sing to you after they kill you?

This has serious potential. Think about it. Pitch dark corridors, perfectly silent, and then suddenly, you hear the singing. One creepy little lullaby, and then slowly more electronic voices join in chorus, and you notice the sudden appearance of glowy red eyes all around you.

Then you scream and start running. Or die.

Valve, make this happen.

Mav....Never apply at Valve.
:aaa:

Counterpoint: Mav, apply at Valve.

personally I think it would be better if it wasn't creepy, but what you'd expect a lullaby to be. Though I think the comic is supposed to explain the singing turrets at the end of the game

Played the first two levels with a friend. It's more Portal, which is great. GlaDOS is as hilarious as ever. Also Portal 2 is $15 for a brief time to celebrate, so if you don't own this game GO BUY IT NOW!

My brother left me out in the cold midway through the co-op campaign and hasn't picked up the game since. So, I'm looking for a co-op partner for the DLC, and I haven't played the last 2 or 3 sections of the original missions either!

still new to the co-op if anyone wants to play sometime
