If you’re running an ARMA 3 server, you’re probably already familiar with the immersive and tactical gameplay the series is known for. But what if your community is ready for a new experience, a fresh environment, or simply wants to explore another battlefield? Changing maps is one of the most effective ways to keep your ARMA experience feeling new and exciting. Whether you’re hosting a public server or playing with friends in a private environment, knowing how to switch maps efficiently is a must.
TL;DR
To change the map on your ARMA server, you need to update the mission file on your server, adjust the server configuration files (like the server.cfg and mission rotation), and restart the server. Make sure your server has the correct mods and map files installed before switching. Always back up your existing configuration to prevent any issues. With just a few careful steps, your players can be dropped into a completely new terrain in no time!
Understanding ARMA Maps and Missions
Before diving into the step-by-step instructions, it helps to understand how ARMA’s system of maps and missions works. In ARMA, a “map” usually refers to a terrain—like Altis, Stratis, or something custom like Chernarus or Takistan. Missions, on the other hand, are scenarios or objectives that are played out on those terrains. You need both a map and a compatible mission file to properly change what your server is running.
ARMA maps can be official Bohemia Interactive terrains or community-made mods available via the Steam Workshop or other sources. When switching maps, make sure the players have access to the required mods if applicable.
Step 1: Install the New Map on Your Server
First, you need to ensure the server has the desired map installed. If you’re using a default Bohemia map like Malden or Tanoa (DLC required), you’re good to go. Otherwise, follow these steps:
- Download the Map: If it’s a mod map, subscribe to it in the Steam Workshop if using SteamCMD, or get the files manually if hosting locally.
- Upload to Server: Transfer the map and any associated mods to the server’s @modfolder. Use FTP tools like FileZilla if needed.
- Update Startup Parameters: Add the mod folder to the server’s launch parameters using -mod=@mapmod.
Without these steps, the server won’t recognize or load the map, and players will receive errors upon connection.
Step 2: Add or Create a Compatible Mission File
Once the map is installed, you’ll need a mission file that runs on that terrain. Mission files are commonly found in a .pbo format, which contains all the scripts and metadata needed to launch the game mode on a specific map.
You have a couple of options here:
- Download Pre-made Missions: These are available on websites like Armaholic, Steam Workshop, or community forums.
- Create Your Own Mission: This can be done using the ARMA 3 Editor. Just make sure to export the mission to multiplayer and pack it as a PBO.
Upload the mission file into the mpmissions directory inside your ARMA server’s root folder. Match the file naming convention, for example: co40_domination.chernarus.pbo, where chernarus is the map name.

Now that the files are in place, it’s time to tell your server to load the new mission using the server configuration file (server.cfg). Open the file and look for a line like this:
class Missions
{
class Mission1
{
template = "co40_domination.chernarus";
difficulty = "veteran";
};
};
Update the template string to reflect your new mission’s filename (without the .pbo extension). Ensure the rest of your config aligns with the server settings you prefer, such as player count, difficulty, voting settings, etc.
Step 4: Optional – Configure Mission Rotation
If you want to allow multiple maps or missions to rotate automatically, you can list several missions inside the same server.cfg under the class Missions array:
class Missions
{
class Mission1
{
template = "co30_rescue.altis";
difficulty = "recruit";
};
class Mission2
{
template = "co40_domination.chernarus";
difficulty = "veteran";
};
};
This configuration will cycle missions after each game ends or when forced via server commands.
Step 5: Restart the Server
After saving the changes, restart your server. This can usually be done via your server’s control panel or by issuing a system command (e.g., systemctl restart arma3server if on Linux). The server will load the new map and mission on startup.

Sometimes things don’t go as planned. Here are some common issues and how to address them:
- Map not loading: Make sure the mod is properly installed and the server startup parameters include -mod=@yourmod.
- Players disconnected upon joining: Ensure everyone has the required map and mods installed on their client-side setup. For mod-heavy servers, use tools like ArmA3Sync or a mod preset launcher.
- Wrong mission loads: Double-check the mission filename in server.cfg and confirm the .pbo file exists in the mpmissions folder.
It’s a good idea to verify your changes by checking your server logs, located in the server’s root directory, usually under arma3server.rpt.
Best Practices for Map Management
To streamline and enhance managing maps and missions on your ARMA server, keep these best practices in mind:
- Backup Files: Always back up the server.cfg and existing mission files before making any significant changes.
- Maintain Clean Folder Structure: Organize mods and mission files meticulously. Label folders and keep unused files archived elsewhere.
- Use SteamCMD: For quicker and consistent updates, use SteamCMD to fetch and install new maps and mods directly from the workshop.
- Inform Players: If you switch to a modded map, prepare a guide or post/download link so players can install what they need ahead of time.
Conclusion
Changing maps on an ARMA server might seem a bit technical at first, but with practice, it becomes an essential skill for any ARMA server admin. Each map offers a brand-new tactical playground with its own character and storytelling potential. Whether you’re moving your squad from the grassy plains of Altis to the dense forests of Tanoa or the war-torn streets of Fallujah, map changes elevate the ARMA experience from great to unforgettable.
Stay organized, double-check your config files, and embrace the opportunity to keep your community engaged with fresh content. With your new map in place, it’s time to hit the ground running in a brand-new tactical scenario.
