Pros:

Not as dark as the other Apocalypse

Cons:

Endless crate mazes. No one would stack crates and racks like that before the apocalypse, and what idiot would make line of sight so hard with such mazes AFTER the apocalypse?

Conclusion:

Yeah, after the zombie apocalypse, the survivors spent all of their time designing wacky mazes out of crates and storage racks so that you could not see zombies until you turned the endless maze corners. Not! Ridiculous level design, better designed for mice looking for cheese. Didn't feel like running through this obvious maze for the rest of the levels, keep it.
