Worst pack yet. "LOLUBTROLLIN'" ... no.
Drive-In really just feels like a Firing Range+Nuketown, Silo is about as boring of a map as you can make, and Hazard looks pretty cool but the maps basically the shape of a doughnut in that you can't REALLY run through the middle of the map without getting gunned down. The only thing keeping this pack worthwhile is Hangar 18.
I have yet to play Zombies, but any time I played Zombies in the past was just for achievements.
Agree? Disagree? Shoot.
Hangar 18: 4.5/5
