Their downloads come with an installer that you run and that's it. But if you are downloading from somewhere else you might have to place the custom map files to your mod folder manually. To find the mod folder in the first place you need to set your computer to show hidden folders and files.
Follow these steps to display hidden files and folders.
Open Folder Options by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.
Click the View tab.
Under Advanced settings, click Show hidden files and folders, and then click OK.
Where to find the mods folder:
You should find the mods folder following this folder path: C:\Users\Your Name\AppData\Local\Activision\CoDWaW\mods
If you have trouble finding that location click the windows start button and search: %appdata%. Open the roaming folder. Then from the top of the window where it shows you the folder path click the AppData. After that open the Local folder and from there you should find the Activision folder.
Starting to play the mod:
Start World at War and in the main menu choose MODS. This will show all the mods correctly placed on your mods folder. Load the map you want to play from the list that will show up. With new maps, the main menu should now have option to start the map right away. But if you are playing some older custom zombie maps you have to load the map trough console.
Enabling developer console and loading the map: In the main menu go to options/controls, then select Game options and from there you can enable your console.
When that is done, press ~ on your keyboard to bring up the console. Type into the console /devmap *and here the map name* For example if you load mod called nazi_zombie_death from the MODS section. Then you need to open your console and type in: /devmap nazi_zombie_death Press enter and the map should load!
How to bind helpful shouts
For example, Pressing 5 will automatically say: Max ammo, reload! in the chat.
To bind keys you need to open the console. Check Enabling developer console from the previous section if you haven't already.
Open console and type in: /bind After that press space and add the key you want to bind, in this example we will use 5. So it will look like this: /bind 5
Next press space again and add say. It will look like this: /bind 5 say
Last step is to add the message you want. In this case Max ammo, reload! So in the end you will have: /bind 5 say Max ammo, reload! Press enter and your bind is done!
Q: There is no mods folder in CoDWaW folder? -If there is no mods folder you need to create a new folder and simply name it mods.
Q: How to find games/people to play with? -Best way is to make friends to play Custom maps with. I have made steam group that has plenty of zombie players. Be free to contact people and gather friends for some Co-Op games. http://steamcommunity.com/groups/Group935
