There should be a jumping button. I love to play this game and all but walking around things is getting boring. I don't care if you have to hold the Jumping button for a while to jump because I would get used to that. I also get annoyed how your guy never leaves the ground unless he is in a air vehicle or skydiving. Also a diving button would be good. Like if somebody throws a grenade in the building and its gonna explode in 5 seconds you can jump out a window or if your getting shot at and you need cover dive over those short walls. Please add a button like that, it would be nice.
P.S. I know there is a button to walk over small walls.
