The next chapter in the #1 rated RTS franchise thrusts players into a hellish war torn landscape to command two battle-hardened armies in relentless campaigns for honor and country. Players lead the tenacious British 2nd Army during the heroic World War II liberation of Caen, France, and command the German Panzer Elite as they struggle to repel the largest airborne invasion in history.

Usefull information for how to use the additional Combiner. Note that the combiner need to be updated for each version of Eastern Front.

The combiner mod is an add-on of NHCmod.
The "combiner mod" allows you to play "Company of Heroes: Eastern Front" with "NHCmod" and "Joint Ops" at the same time.
You need to download both "NHCmod ToV" and the latest "Company of Heroes: Eastern Front" to use the combiner mod!

How to start the combiner mod?
Once you have installed correctly EF and NHC in your Company of Heroes folder (check it!), you can start the combiner mod.

To start the combiner mod, click on the shortcut on your desktop or on "Combiner.bat" in your "Company of Heroes" folder. It will automatically load both mod and mix them.

The Eastern Front mod is available here:
(It is a very big mod so it is highly recommended to defrag your disk after installation)
If you don't have both mod, the game will crash. Note that the Combiner gives priority to Eastern Front. So every features of
Eastern front are present with the combiner some part of the NHCmod are missing (e.g. Light tank cannot crush infantry, lower max pop than in NHCmod, ...)
The combiner also supports the Joint Ops mod which can be downloaded here: (with installer) (without installer)

BONUS: Another add-on is available for the NHCmod. You can have german voices for Whermacht and PE and English for US and Commonwealth.

How to do that?
Simply download all the files from here:
and put them in the "NHCToV" folder. The mod will automatically load them.
If the forum is down, here are the links for the needed files: (German voices for Wehrmacht) (German voices for PE and English voices for Brits part1) (German voices for PE and English voices for Brits part2) (English voices for US Skirmish) (English voices for US SinglePlayer Missions part1) (English voices for US SinglePlayer Missions part2) (German speech file for Tiger Ace campaign) (English speech for 2nd ToV campaign) (The original German speech file with one file from english version for 3rd ToV campaign)
(It is recommended to defrag your disk after installation)

How to play LAN/internet multiplayer game with the Combiner?
The public version of the combiner does not allow you to play in multiplayer. You will have to get it yourself.
Here are the step for making it run yourself:
- Download and install Corsix mod studio (
- Download and install latest Eastern Front (
- Download and install latest NHCmod (
- Find your Company of Heroes folder
- Copy all the files from the folder Company of Heroes\Eastern_Front to Company of Heroes\Combiner_Full
- Run Corsix chose "Load Single SGA Archive"
In your company of heroes folder:
- Open \NHCToV\Archives\attribarchive.sga
- right-click on "attrib"
- Select "Extract all in this folder"
- Click on Go!
- Select find the path to THQ\Company of Heroes\Combiner_Full
- Then click on "Ok"
- Close Corsix

- Do the same for \NHCToV\Archives\Data.sga and \NHCToV\Archives\sound.sga

- Repeat all these step for \Combiner\Archives\attribarchive .sga
- Repeat all these step for \Combiner\Archives\Data.sga (right-click on "attrib" become right-click on "data")
- Use Combiner_full.bat to launch the full combiner.

There is absolutely no guarantee that this will works even if you follow all these steps exactly.

NHCTov does not appear to load with Eastern Front after I completed the Corsix extracts?

Did I miss something?

You don't have to open the Eastern Front mod with corsix. Just copy all the files by hand (copy-paste) in the Combiner_Full folder.

I did that. I unloaded all mods and repeated the steps. I did note that the Combiner\archives\attrib.sga is actually Combiner\archives\attribarchive.sga. Not sure if this make a difference.

I also noted that EF attrib is under combiner_full\dataattrib\attrib and NHCTov and Combiner attrib's are under combiner_full\attrib.

The combiner_full mod attrib statement only looks at combiner_full\dataattrib see extract below.

folder = Combiner_Full\DataAttrib
archive.01 = Combiner_Full\Archives\AttribArchive
archive.02 = WW2\Archives\AttribArchive

Do I need to copy the combiner_full\attrib to combiner_full\dataattrib\attrib to merge files?

Yes, all attrib should go to combiner_full\dataattrib\attrib

Do I over write any of the EF attribute files with the NHCTov attribute files or am I suppose to keep the original EF files?

The reason I'm not sure it is loading properly is because I get no aces, pershing or tiger

I figured out that I needed the DATA.SGA from NHCTov mod as well as the Attrib.SGA.

It works now in skirmish mode but when I try multiplayer for lan game I get a crash report and shut down of the game once I select Host Game.

Any ideas?

You need to extract all the files insides the .sga files.

I will back up and retry the entire steps in case I missed one. Thanks for responding. Great mod and I hope I can get it to work in multiplayer for our lan games.

I know it is not easy to get it works in multiplayer. I am not even sure the tools and indications I have given are enough. Good luck. Only the sga files of NHCToV and Combiner need to be extracted not the ones of Easter_Front.

I have a few questions about the readme for the combiner:

'The public version of the combiner does not allow you to play in multiplayer. You will have to get it yourself.'
Get what myself? The ability to LAN? Some non-public release?

'- Repeat all these step for \Combiner\Archives\attrib.sga'
I don't have that file, I only have \Combiner\Archives\attribarchive.sga

Are there only three files that I need to extract
(attib.sga , attribarchiva.sga and Data.sga)?
