*Note: Some weapons still need a little balance tweaking, just haven't gotten around to it yet.
Included Weapon list:
Sorry but you are not allowed to view spoiler contents.
Place the weapon includes from Zone_Source includes into zone_source/MAPNAME.csv.
Place both (_zombiemode_weapons.gsc and dlc3_code.gsc) into ROOT/Mods/MAPNAME/Maps.
Copy & paste all of the weapons into ROOT/Mods/MAPNAME/weapons/SP.
*NOTE: You can copy/paste each individual weapon include from _zombiemode-weapons.gsc and dlc3_code.gsc into your versions, but its MUCH easier and faster to just copy & paste mine.
