Just as the title says, I'm willing to help people with gaining the coop achievements. I have all the DLC but I can delete it if you don't have it. Gamertag is Doktor ICE. Just send a message saying you would like help, and I'll gladly join you. One other thing, I don't use nor have a mic, which isn't a big deal as I'll pretty much just follow you around completing the missions. :)
