IGN: This map pack for a six month old game has some serious quality inside. It's great to see Treyarch presenting some inspired level design and unique new angles on zombies this far out in the game's life cycle. Nothing in the First Strike pack struck me as exciting as what you'll find in Escalation.
Tried these maps on my friends xbox360 today they are lame as hell do you're self a favor and don't buy them they're just a waste of money.
