    This DLC is hillarious. I loved the way GLaDOS acted in this DLC, the test chambers were challanging and fun. I actually found myself laughing a number of times when playing this DLC. I love the design style too. Construction-backstage style. I really wouldn't fault this DLC. Loved it. Start to finish. Expand

    This review contains spoilers, click expand to view. This DLC is really awesome, a new fresh co-op course (the joke ending is very hilarious also), challenges and leaderboards. Plus you get it for free!!! Expand

    The new co-op course is awesome, it's well designed, challenging, and creative. The challenge mode however, is not as polished as I was expecting Valve to make it. It seems like to thought went into adapting the levels for it, so the parts of it where you have to stop to talk to Wheatley and GLaDOS etc are still there, so every time you start a chamber again, you have to go through it all again. Valve making me start to hate the dialogue in Portal 2 is something I am not happy with. Still, I'm looking forward to the next batch of DLC, and I'm sure that by then the Challenge mode will surely be improved by numerous patches. I would have normally given this an 8, but seeing as it's free, it's a 9. Expand

    Not bad for free DLC, but as always, I am left wanting MORE. The Co-op levels are pretty well thought out but like the Co-op levels in the retail game, not that hard. The challenge mode will add a little replay value to the game, but again, more new content is needed. Expand

    One poor free DLC and nothing significantly new out of this besides the co-op campaign. The SP challenges are not the new and modified maps and I could have expected more. But it's early for a better DLC for now. Expand
