November Outpost-2 UO-map CoD

The map november outpost is now fully adapted to the CTF gameplay.

Its maker, Musashi, still wanted to finalize this map he made for CoD-UO.

As it was his first map for CoD-UO and new to the CTF gameplay he got some help in finding the right type of spawning points the CTF needs.

Its a pro-made map. And Musashi is now playing CoD2 so lets hope the new CoD2 map-editor will inspire him to make his maps for this new CoD aswell. GJ.

Final story on 'weapon file error' in Cod:UO

Call of Duty UO Archive


by CC

For all players and gameserver-administrators the answers are given on the questions about map and server-related errors in CoD:uo. And to fix some of those problems a special Custom_Map_Fixer.pk3 is made and can be downloaded

First what errors are we talking about here: 

weapon file error cod

Player-side :

1. The 'weapon file error' a player gets when he/she wants to join a server with custom maps in rotation. The player has the same map as running on the server in the uo-folder.

(Error example used here is: Could not load weapon file 'weapons/mp/dp28_stand_mp' but it can be also the mg30cal_stand_mp, mg34_stand_mp etc. )


In some cases when the player set the download-option in multiplayer on 'ON' the problem will be solved.

Many players dont like all the extra's you get on servers so they have the download-option standard on 'OFF'.

Warning: Recieving all kinds of different versions of same map can lead to an other error: the 'Unpure.pk3'.
And the download of the various modifications will lead to a 'Unpure Client' error.

2. A player has the same map as running on the server and download option is on ON but still he/she gets the 'weapon file error'.


This can be the server that doesnt support autodownloading or the server simply ran out of autodownload-resources.

Server-side :

3. A server-administrator has choosen some nice custom-maps for in the maprotation on the server.
The server's autodownload function gives the players the custom maps that are in the rotation.
But still some players cant join the server because of the 'weapon file error'.

4. When joining a server a new visitor gets the custom map thats is running on that moment but also gets 1 other custom map. Why?

5. A server-admin cant understand why the amount of bandwidth-GB's used by the download function is so high.
This compared with the sizes in MB's of the custom maps used in rotation and the number of new players that come on that server monthly.


And for these 5 above questions there is only just 1 answer.

There is just something missing. Or better said: forgotten.

Most (!) of the custom maps in CoD:UO are missing some weapons files.

"Invalid .pk3" or "Unpure Client" messages !!

If you experienced messages like: "Invalid .pk3" or "Unpure Client" and get kicked from servers when map rotates dont blaim Call of duty or those servers.

But it is YOUR CoD-uo file on YOUR PC that will be FULL with auto-downloaded mods and crappy maps...

Below is a screenshot of the Call of Duty Main & UO folder with the original files after a fresh install of Call of Duty, Call of Duty United Offensive, Patch 1.51 and the CoDUO Official Map Pack .


To avoid potential "Invalid .pk3" or "Unpure Client" errors use this screenshot as a reference to clean out (delete) all "3rd party" (non-Activision files) maps and mods in your Call of Duty game uo-folder.

When you get the errors mentioned above its because they originate from map & mod files that reside in your Call of Duty/Main and Call of Duty/UO folders.

And its from downloading multiple maps and mods when having "Allow Downloads = Yes" in your Multiplayer Options. (This will be especially if you never not un-installed and re-installed Call of Duty after purchasing United Offensive or if you still play on Call of Duty Servers.

Still many people dont have the uomappack00.pk3 standard in their UO-folder.

The uomappack00.pk3 is an official mappack distributed for Cod United Offensive.

This mappack contains: Streets, Dawnville, Harbor, Powcamp, Peaks, Carentan, Depot, Hurtgen

Some custom maps use parts of these maps!

Download uomappack00.pk3

1. Extract the uomappack00.pk3 file from the zip folder.
2. Place the uomappack00.pk3 file into the uo folder, located at c:/Program Files/Call of Duty/uo.
