CoD2 and UO mods?

[CaptCom]

I don't remember if CoD2 and UO need a mod to run custom maps.
If someone can tell me

No just create an .iwd with your map and type ''/(dev)map mp_mapname'' in the console
and if you want to run it on a server you don't have to run a mod.

No mods to run custom maps, just put em in & away you go, no fixes, no mods. No hassles....
Cod requires the .pk3 to be in the \main folder
UO requires the .pk3 to be in the \uo folder
Cod2 can't have too many custom maps 4-6. It requires the .iwd to be in the \main folder
The demise continued from there.
