I really love the game and the different terrains that you can play through. During the playthrough, it seemed like the spawn point for the zombies was fixed on the player at a certain point, so they kept spawning on top of each other, causing a huge cluster of enemies. I think a big thing with zombie related games is that they can sneak up on you. With the camera view however, you can see all zombies coming at all angles. One game with a similar camera perspective is Project Zomboid, but the zombies are only visible if they are in the players frame of reference (which direction they were standing in). I think that could really add to the gameplay, even if it is a harder setting that the user can select.
