Okay this is for you who bought DoD Retail v1.0. Yes ESF will work with it but you can't change your controls and it seems to kick you out of a server when you try to join (I got in once). Although you can create a server. I am trying to find a way to fix this but I can't seem to register on the Day of Defeat Forums. So just hold tight and Ill try to find a way to fix this... I hope.
