In some ways, I agree. In others, I don't.
The key feature that keeps Bluzone together is it's community. The whole "people interacting with each other" in a different world is what keeps bringing people back. It sets them a story, an experience that could not be achieved in other ways. Life as a person in a crumbling society constantly attacked by military forces and zombie raids. But there's one slight problem.
Zombies aren't zombies, they're just petty obstacles that die with one hit of a crowbar. In my opinion, this should be different. The first flaw is the zombie's AI, they should form hordes and slowly crawl around the city, where as now they spin in circles and hop like bunnies. Two, is the zombie's health. You could have a clothes hanger and knock down 3 zombies in a second, I mean, seriously. Guns however, take two shotgun round's worth to blow open a head. Third, is the community's reaction to the zombies. Normally they'd charge straight to the zombie and finish it with a single hit, but I mean, come on, not everyone is a professional gunner. People should get scared at the sight of a zombie, they should react by staying low and keeping quiet, trying not to attract the zombie's attention. Of course though, the zombie's AI has eyes on the back of it's head.
To me Bluzone is more of a "Oh god there are two armies fighting above our heads" Instead of "The apocalypse is here, we should find food, water, weapons and a barricaded home". I really hope this doesn't offend anyone, especially Kniaz, and I hope you take note that I'm just sharing my opinion :).
