i was tryin with notepad. that must be the problem. thanx.

@Highblur

could you explain what you did to pull it off exactly. i looked in the xml but could not find where to put the "x". (an example would be explanatory)
and how do we implement the silenced (m4) sound to the desired gun.

thanks in advance.

i guess the mod only covers the normal difficulty mode, the easy and the hard modes needs the editting of "Ammo_easy.xml" , "Ammo_hard.xml" etc. files.
