Replaces the simple zoom for weapons without scopes with full iron sights. It doesn't simply use an image, the front and back sight actually line up in the center of the screen over the crosshair. There is a new option to remove the crosshair.
no 64bit implimentation, but awesome mod nonetheless. it takes one of my constant gripes about the game and made it better. can't wait to see if fcam will 'borrow' from this!
