At military base and I was shooting zombies and went up the steps to military sniper lookout/tower and as they were coming up I was shooting them and downed one and it was outside the sniper box on the rails preventing me from being able to move inside the sniper box and was slapping me until I died. I had spent many of hours in real time surviving to die due to being unable to move because this game has so many bugs. This is the main reason I had stopped playing the game 6/7 months ago. Please fix this issue. Unfair to spend all the time and hard work to survive to die because game is polished and ready for playing.
