Nice work!   :+1:
 

Maybe you have noticed that the player is facing into one direction and is unable to rotate?
How to fix this?
Using a script_origin is the answer!
 

script_model = spawn("script_model", player getTagOrigin( tag ) );
script_model.angles = player GetTagAngles( tag );
script_model SetModel( "tag_origin" );

script_origin = spawn("script_origin", player getTagOrigin( tag ) );
script_model linkto(script_origin);
script_origin linkto(player);

By linking the  'script_model' to a 'script_origin' and then to the player, this issue no longer occurs.

It's best to go here: Gympie6's Scriptplacer
And download the Sniper Bolt's Tutorial V2.0 zip file.
This includes the mystery box prefabs.

Normally it's `sound,SOUNDALIASFILE,,all_sp`
 
If it doesn't work it could be that the porter used the wrong sound names or they are missing.
 
You can check it by comparing the weapon file and the sound alias.
 
There is a tool what can help you inspect the weapon file called: UGX WeaponsEditor++ v1.0.0

hmmm?
 
To add weapons to a mod these are the steps you need to do:

• Is the weapon added to _zombiemode_weapons.gsc
• Is the weapon added to _dlc3_code.gsc
• Is the weapon added to the Call of Duty World at War\mods\MODNAME\weapons\sp folder
• Is the weapon added to the modbuilder or mod.csv file?
• Is everything related to this checked in the modbuilder?

The only thing I can think of is that your weapon file is not in the weapons folder in 'mods/MAPNAME/weapons/sp'?

This is a really nice good looking map!
I am sad to see that this level is so short.
But heey I enjoyed this map a lot. Thanks!

Have you checked this topic: https://www.ugx-mods.com/forum/sounds/57/updated-tutorial-adding-different-round-sounds/2211

You may also post it here if you like or make a youtube video. 

I have no idea what you mean.
In case you have troubles downloading the map you can also look here: https://callofdutyrepo.com/2022/07/01/subzero/

Yes!

I am looking forward to your full review of the map. (PHD is actually in the map but it's a hidden easter egg, I am curious if you can find it.)

Open: 'dlc3_code' inside your modfolder. (Add the file to MAPNAME/maps, if you don't have this file.)
Search for this: 'include_weapon( "zombie_ppsh" );'
 
There you can add weapons to the mystery box.
 
With this: 'include_weapon( "zombie_ppsh_upgraded", false );' can you keep weapons out the mystery box.

I considered it. Since it looks like a beautifully made map. But I'm quite strict in adhering to my no-endings rule. In any case, I commend you on the attention to detail and creativity. Thanks for the advice, I'll definitely look into it.

Go with the flow. This map is not boring, trust me.  

I try developer 1 but it doesn't work, I don't know where to look for this "field object is not defined"

 
When you open your console: "Shift" + "~"
Where does your error come from?
In my example I added some points which cannot be read by the game.
