Call of Duty bo3: ZM LILArny

In order to fix the Lil'Arnies taking away the player's primary weapon slot you need to edit a stock file from within your usermaps folder and include it in your Zone file.

Editing the Stock file

• After creating your Map in Launcher (let's say zm_yourmap) navigate to this folder:

...\SteamLibrary\steamapps\common\Call of Duty Black Ops III\share\raw\scripts\zm\

• Locate and copy the following file: zm_usermap.gsc
• Now navigate and copy this file into your map Script folder:

...\SteamLibrary\steamapps\common\Call of Duty Black Ops III\usermaps\zm_yourmap\scripts\zm\

• Open this file now from within your Scripts ZM folder with your preferred Text Editor - I recommend Sublime -
• Locate this line in the file:

zm_utility::register_tactical_grenade_for_level( "cymbal_monkey" );

• now add the following line underneath it:

zm_utility::register_tactical_grenade_for_level( "octobomb" );

• the resulting function should now look like this:

function offhand_weapon_overrride()
{

zm_utility::register_lethal_grenade_for_level( "frag_grenade" ); level.zombie_lethal_grenade_player_init = GetWeapon( "frag_grenade" );

zm_utility::register_melee_weapon_for_level( level.weaponBaseMelee.name ); level.zombie_melee_weapon_player_init = level.weaponBaseMelee;

zm_utility::register_tactical_grenade_for_level( "cymbal_monkey" );

       zm_utility::register_tactical_grenade_for_level( "octobomb" );

level.zombie_equipment_player_init = undefined;

} 

• Save the file and open your Map zone file (you can use Launcher, right-click)
• Add this line:

scriptparsetree,scripts/zm/zm_usermap.gsc

• Save, Link your map and you are done!
