Cherno. No surprise. Don't hang around large towns and don't be so obvious by climbing up on top of buildings. Night time is safer from both other players and zeds. Probably best never to change servers if you've managed to get in there safely, leave the same way. If you change servers you won't be aware of your surroundings. Now that is awesome. I assume you didn't have a gun when you were taken hostage. Do you know about the gamma trick to help see better at night?
