So my coworker is awesome and lent me his household's extra 360 until I get mine back from the doctor. Which is good, because after only one night I was already going through serious L4D withdrawals. It has a wonky disc drive, so nine times out of ten it won't read the disc. I am persistent however, and will do whatever it takes to get my game on. So if you send me an invite and it takes me about 10 minutes to join, that's why. Beggars can't be choosers though.
Also, I highly recommend playing co-op with Detry while he's completely hammered. It is a hysterical experience. :)
