And that is their right. As much as I, or anyone else disagrees with the childish sandbox antics, its still their right to takes their toys and not let you play with them.

What about “Nightmares”? Technically a second campaign with zombies, which ties a lot together. I found it unlocked after completing the first campaign and currently working through. I find it a good mix of both games but more enjoyable than Zombies alone.
