There's an issue I want shed light on regarding Zombie escape server. When I was playing on map ze_Box_Final, I noticed players found a perfect spot where they can camp for long time which causes unbalance game playing between the teams. In general, players have to press the buttons "A+W" to keep moving forward in those valleys that pushes them into sides. However, CT players have found site next those valleys in order to shoot zombies and pushes them with a single bullet. Therefore, they started abusing it too far by camping for long time and prevent zombies reaching to the end, so I suggest you to add camper zone there for 5 seconds and the issue will be solved
