I added the WAW Maps to this
You can download here or copy the code into a gsc file and follow next step Custom Wallguns.GSC Download
Once you have the gsc put it in Local\Plutonium\storage\t5\scripts\sp\zom if you're running a server
if solo put the script in the folder to the corresponding map.

////// CUSTOM WALLGUNS BY HERCULES#8024
//////
////// "Five"/Ascension/COTD Presets by IceHot#3232 (but not a supporter of HERCULES#8024 though)
////// Check out the original mod if you haven't yet (or downloaded it on my forum): https://forum.plutonium.pw/topic/27796/zm-custom-wallguns?_=1687210456052
//////
////// SPECIAL THANKS TO Pistakilla#5053 AND shippuden1592#9641 FOR POINTERS AND EXPLANATIONS
//////
////// THIS IS MY FIRST PUBLIC SCRIPT AND I HAVE TESTED IT EXTENSIVELY, IT SHOULD JUST WORK.
//////
////// Ammo cost is calculated by doing gun_cost*0.5 . Upgraded ammo cost is calculated by doing 5000*0.5 (5000 is a placeholder and might be replaced with a better solution)
////// These calculations are done automatically by using the base price which is set by whoever edits this file.
////// To get coordinates to set your own custom wallguns, just go into a single player game and do notarget and then noclip to the exact spot and do viewpos in console.
////// Doing this will give you the X Y Z cords along with pitch and yaw in the console window.
////// You can find more weapon names here : https://steamcommunity.com/sharedfiles/filedetails/?id=1863755475 //

////// To find out where IceHot#3232 placed the guns at... do "setviewpos x, y, z" - next to the "custom_wallgun("
