Portal 2 DLC I was really excited for the new features and puzzles that the free DLC had to offer. However, I am sorely disappointed by none of my friends actually wanting to play it. I instead have been matched up with randoms who don't have a microphone, thus rendering the challenge modes virtually impossible. I am desperate for a decent partner who I can talk to... I wish there was a search filter in Portal 2 that would only search for people who talk.
