just edit the weapon.txt dude...
Would not work on VC V1.6 multiplayer. You shoot m79 bullets but they won?t harm anyone.....
In fact, without scripting skills the m79 shoots "blanks" in multiplayer as it was not designed to work in mp.
I?ve seen it working in mp once (on an unreleased user created map) but the use was limited to 1 player/map......
Anyway.....you got nades...use them
