I would suggest to change the atmosphere a little, maybe make it more grey. We should be able to run way faster, in order to escape gunfire. Those with guns shouldnt be able to kill in two hits. Maybe in 6 or 7, since they mostly spam the fire button. Or, they shouldnt be able to spam it in first place. Maybe fire rate would be the solution. crouching/lying on the ground. As a smart person, I want to be able to play dead when Im wounded. When a gun is fired, show on the map a red dot to demonstrate where the sound comes from. This will be useful in order to know if you need to hide. Zombies should be scarier. They look pretty dumb right now. I would suggest to watch good zombie movies (ex:28 days later) in order to study the character. Record zombie screams in a studio. Give each one a personality. Make them more resistant, deadlier, faster in order to make the player scared to even approach them. It wont probably happen in the very next update, but the area should be expanded, with more houses, maybe towers, churches, abandoned weapon shops, creepy cornfields, etc... Those are my suggestions for the updates to come. You are doing a great job. I am fully aware it is easier to suggest ideas then actually bring them to life. This is why I wont be really disappointed if you dont manage to bring them all up.
