It is annoying that you can open a door but you can not close it behind you. Any person in this situation would always close the door behind them so that no zombies could sneak in behind them.
Lmfao!. Most of the buildings are 75% gone and you talking about closing doors behind you. Most probably they will get through the window.
Honestly I think you should be able to , I don't get what the big deal would be - it'd just be elminating an extra way for the infected to get to you, even if the buildings are destroyed and theres 100 different ways for them to get you, getting rid of that one way is one less thing you have to worry about. I personally don't care about not being able to close doors.
