This article will explain the steps to install Workshop mods on your ARMA 3 game server you have with us.

Please Note:

Some mods may have different setup steps, or require extra steps after install (such as editing of a configuration file or your mission file). The mod info page or documentation for the mod should tell you this.

You can find the Mod ID, of any mod, or map mod, at the end of the URL. For example:
The id is at the end after id= . So the Mod ID would be 1581857481

For multiple mods, repeat from step 4 on-wards for each mod.

Some mods, will not work with other mods, add your mods one at a time, testing after each to help find problem mods and for a smoother install.

How to install workshop mods:

Login to our TCAdmin control panel and select the game server you want to work with.

Click the "Game Services" button to the left, if you don't see the list of your game servers. If you only have one, you may be directed to it automatically.

Click on the "Mod Manager" button

Install the SteamCMD system you will see here

Go back and click on the "Workshop Mod Downloader" button

In the box provided, specify the workshop mod ID that you wish to install. (Only one mod at a time)

Click execute. This will then download the mod to the root of your game server.

Click the "File Manager" button, and you should then see a folder with the mod ID of the mod you just downloaded

Click the rename button and rename it @something.

Change something to anything you like, it should be one word, without spaces or special characters (other than the @ at the beginning only). You can however use _ to separate words if you wish.

You now need to copy the keys for that mod, to the keys folder for the server

You mind doing this via a FTP program easier. How to Connect to the Server Using FTP. The steps below will be slightly different if using an FTP program.

Still in the file manager, in the mod folder you just renamed, there should be a "Keys" folder, go into this folder.

If there is no Keys folder, you can skip to step 11.

Download the Key in here.

If there are multiple Keys, select them all then click "Create Zip", and download that

Go back out of they Keys folder and our of the mod folder, and look for a "Keys" folder and go into it.

If you don't see one, create one.

Upload the Key you just download, into this folder

If you created a zip of multiple keys in step 10, upload the zip, then extract it.

Go back out of the File Manager and click on the "Commandline Manager"

Select the command line that best suits your requirements, or create a Custom Commandline using the "Custom Commandlines" tab.

Add the name of the mod folder you set in step 8 into either the -mod box or the -servermod box shown

Most mods from the workshop will need to be specified after -mod, some may need -servermod , the mod should tell you this on its workshop page if it is the case.

For multiple mods they should be separated by colon and inside ", for example:


We highly recommend only adding one mod at a time, if you add multiple mods and then your ARMA 3 game server doesn't work, it makes it much harder to find the problem, add one mod, then test, then add another, and so forth, until all mods are added.

Once done, click Apply.

We recommend before starting the server:

Check if that mod has any other steps you need to complete, such as editing a configuration file or your mission file. The mod should tell you on its workshop page or website if this is the case. We advise checking using Google to see if there are any instructions elsewhere.

You may then start your server and if done correctly, your server will now be online with that mod!

How to install mods not on the workshop

We have popular mods that are not on the workshop, install-able via the "Mod Manager" (see step 1 to 2 above, on how to get to the mod manager). Some install-able in one click, others need further steps after install.

If your mod isn't in the "Mod Manager", contact us and we will be able to add it in most cases.

When you have installed the mod from the mod manager, follow steps 9 on-wards above.

Can i manually upload a mod not on the workshop?

This depends, if the mod does not have a DLL file, then yes, you can upload it via an FTP program, or the File Manager.

Please note, the File Manager has upload limits due to webftp timeouts, you must use an external FTP program to install large ARMA 3 mods. Please see here on how to connect using FTP: How to Connect to the Server Using FTP

If the mod has a DLL file, you will need to contact us to upload that mod or add it to our Mod Manager. This is because these files can be manipulated to for example, damage our systems or steal your personal data. Therefore this is done for our own, and your safety and security.


If you get a keys error on join, please see step 9 on-wards above. Contact us if would like assistance.
