When you explore a map, you may run into a door. (See the first screenshot below.) Some new Urban Terror players have trouble opening doors during the game. So let me explain briefly how to open doors.
All you have to do is to set up a button for use/doors. At the main Urban Terror screen, click on
setup. Then click on
misc. Under misc, you should find
(def)use / doors. In the second screenshot below, the button for this task is set to
ENTER. Simply, click on it and change it to any button. Then you will just have to press that button during the game when you run into a door. And it will open.
