Plutonium

Update: I now have the map, Broadcast. I just stumbled upon it on one of the servers. Since I was focused on loading in the map, I didn't notice what server it was on before Plutonium told me I was on an outdated version of it. The map seems to work fine, and works with the add-on waypoint mod for the Bot Warfare mod.
The server it was on, all I remember is that it had it's code name in red text, like 'mp_broadcast', and auto-downloaded a mod called, 'dolphindive'.

Addendum:
I deleted the mod to see which server would auto-download the 'dolphindive' folder in the mods folder, and it was the server, MONOPOLY S&D 100+ MAPS.
There are three servers like this, for S&D, FFA, and TDM. The S&D is the easiest to skip through maps with, since there weren't any other people on it, so good luck finding the maps you want.

Update: I now have the map, Rundown. It was in the server, CoD4 MW2 DLC. For the longest time I couldn't connect, but when I disabled my private windows defender firewall, I connected easily. Hopefully I will get the other two maps with this server.

Plutonium IW5 added the Intervention from MW2, and in Plutonium, I think I've used the Kamchatka-12 from Modern Warfare 1 Remastered a while back, so is there a mod or mods to download the weapons from MW1, MW2 and the exclusive weapons of MW Remastered?

Could it be turned into something other than google drive for the link to be posted here?

Also, the MW2 map Quarry was in the same situation for me as these other maps, but I found it in the map cycle for AIZombies. Maybe the map Rundown is also there, but I didn't stumble upon it there.

I have all the maps from MW1 except Broadcast and Chinatown, and I have all the maps from MW2 except Rundown.
I had the map Broadcast in the past, but I accidentally deleted it and I can't find it again, so any help would be greatly appreciated.

Thanks for the reply, because it prompted me to check again.
I know why I couldn't find it now. It's because since I only play the infected mode with Bot Warfare mod added, the only classes I ever interacted with was the Create Default Classes in the Options for Game Setup. The added guns never show up there (at least for me). They only show up at the starting menu within the Create Class.
Well I guess that's my proper issue then, why are the weapons not there for the Create Default Classes in the Options for Game Setup?

Plutonium has pages about adding in custom things, like Custom Maps: Rust, Highrise, Nuketown, Skidrow, Favela
and Custom Weapons: AK-74u, Intervention
It seems like both the maps and the weapons are meant to be added automatically with IW5, as both of their pages on plutonium are styled in the same sort of way, but I've only gotten the maps, not the weapons.
With my utterly bare-bones understanding of coding/modding games, I assume that adding in the guns, would be easier than adding the maps, with the easiest thing to add being the AK-74u, since it's already in the MW3 campaign and spec-ops, and the hardest thing to add being Nuketown, since it's not even from a MW game, but a BO game.
Anyway, I would be satisfied with help to at least use the AK-74u.
