This is a pretty high-quality shooter. It reminds me of bioshock 1 or farcry 3, and the roguelike aspects were cool to see. My only criticisms are 1. that it got to be too easy and 2. that at a certain point the zombies were no longer touching the ground and then all I could do was shoot the zombies out of the sky with a shotgun (which was still very fun). Other than those two things, it is absolutely great.
