How do ya get more than 3 k98 nades
 

The problem I continue to have is that even though I modify k98_mortar.tik to reflect 5 rifle grenades, the game still only gives 3. I figure that I have to change something in the scr etc. files or something.
I don't have an editor.

You mod the tik file, read your thread over at TMT and download the modded tik.

Btw I use notepad for editing scr, tik, shaders etc.
