Why is there only one map? Why is there just one mode? There should be a mode where players only focus on zombies and cant kill each other. Graphics are really nice, gameplay is great, just sick of same map over and over. Game also crashes from time to time, not often though. To the developer, fix everything I outlined, I ll come back and change to 5 stars, you only get 4 now. Spawn time should be 5-10 seconds, 15 is BS. Round time should be 10 minutes, 4 is too short. There should be a one player mode, just to shoot hordes of zombies.
