Bungie, please bring this back as a social playlist. I work and go to school and could only play for like 45 minutes but it was awesome. The few times when I was the last man standing I thought I was going to have a heart attack--jamming up your entryways with boxes isn't so good when you have 30 seconds left and you're trying to make a quick vehicular escape from a swarm of mad zombies! The one thing is, the zombies seemed overpowered. Almost every game ended with the Zombies winning fairly quickly. As a human, you barely had a fighting chance. Please please bring it back on social--it might finally get a few of my zombie-loving friends who I keep trying to talk into getting an XBOX 360 finally buy one. Cheap marketing, right?
