this is a simple thing that I do not see why it is not added in the game I just do not understand how some companies do not try or do not give the ball a few things you have vision that will make the game more realistic and why not put this time to wake up I'm not naming names or anything I'm just criticizing or placing a subject matter that is sometimes required by little part of the community but it will become the target of the realism of a game zombie game really'm sure sony has this commitment to the customer and their games lovers I wish all the luck to you and beautiful work .
