How to Install Epoch.
By ♔ Princess Sparkles ♔
How to manually install Epoch Mod for Arma 3 and how to play on Chernarus map.
Downloading and Installing Epoch Mod.
1. You will need a full version of Arma 3 downloaded and run at least once in your game library.

2. You will need to have a BitTorrent client installed on your PC to download the mod files. If you do not already have one I recommend μTorrent®.

3. Go to to download the mod. I suggest you use the link but you can also use the Direct Torrent link.

4. Once downloaded, go to your downloads and unzip the @epoch file, then move it to your Arma 3 folder which is located in Computer > Local Disk (C:) > Program Files (x86) > Steam > SteamApps > common > Arma 3

5. Once your @epoch folder is in your Arma 3 folder go to your library in Steam and right click on Arma 3 > Properties > Set Launch Options.

In this box you need to enter a launch parameter that tell Arma to run the Epoch mod. Type in the box -mod@epoch; and click ok.

6. When you launch Arma now, you should see the Epoch screen when the game loads, click continue.

7. Click play > multiplayer > Filter then type epoch into the host box to find all epoch servers.

8. You will be able to play on some Epoch servers now that you have Epoch installed, any servers just using Epoch (|1.38) will be able to play on.

You may not be able to get on some servers, you may get an error message on joining a server or you may just get kicked back to the server list. The reason you cannot join certain servers is due to the fact that they are using other mods that you need to download in order to play. To find out what files you need to have installed to play on a specific server, click on the server and look in the bottom right corner.

I have detailed how to download Mas weapons and Emod expansions in order to play on Overpoch servers in a separate guide which you can find here:

Downloading and Installing AiA terrain pack to play Chernarus.
1. Make sure you have followed the steps above and installed the latest version of Epoch.

2. Go to and scroll down under "Optional Downloads" click on Direct Torrent and download.

3. Once downloaded go to your downloads and extract the @allinarmaterrainpack zip file, then move it to your Arma 3 folder located in: Computer > Local Disk (C:) > Program Files (x86) > Steam > SteamApps > common > Arma 3

4. As before you need to add a launch parameter to Steam to enable this mod to run. So add @allinarmaterrainpack on the end of your epoch parameter. It should now be: -mod@epoch;@allinarmaterrainpack;

5. You are now able to play on any epoch server which requires AiA terrain pack.

NB: Please ensure you have no other launch parameters for other Arma 3 mods enabled, which may conflict with Epoch.

Hey guys nube here..Was wondering if I have it installed can I host it on my pc just as is from the download? I want to play it just with my wife and buds when ever I am home. I have it but when I launch it just shows all the characters half way into the sand. Is there something else I have to do to play host it on my pc or can only people with servers do so?
