Pros:

Scary atmosphere (just the 1, 2 map).
Random jump scares

Cons:

Too many zombies, looks like survival
No direction sense
Too dark

Conclusion:

The last map was the hardest for me, i couldnt find a way to get out of there. Too many zombies getting in my way, and i think the last stage was a little confunsing for me.. i mean, i dont know if was just me but my sky was pink and black, like... what? didnt get it. I enjoy it anyway.
