Thank you. Looks pretty simple )

I followed the instructions on the wiki and the game craps out when you actually get beyond the in game movie at the start of the campaign. I found you also have to copy the "VoiceRH.pbo" file from the game's original discs and place it in the "/AddOns" folder in your game folder.

I've updated the wiki entry. Thanks for the heads-up!

Thanks for this info. It bugged me that Red Hammer wasn't included, luckily I found my old discs. The intro movie seems glitched with the dialogue skipping some bits and being out of synch with subtitles. But I recall that the original OFP had glitches in movies sometimes. The first time I finished Resistance for example the two attack helicopters in the final movie actually collided which was pretty stupid. They didn't do that the second time.

I came searching for the same answer.

Unfortunately, I do not own Red Hammer in CD format.

I paid for Operation Flashpoint: GOTY Edition which included Red Hammer. Unfortunately, I had to reformat the machine, hadn't time to do a backup and ended up downloading CWA...which does not have Red Hammer....and the only campaign left to complete was Red Hammer :(

Is there any way to download it to from somewhere?

And for Resistance expansion what could it be done?

Way too late, but I bought a disc version. some kind of PC-gamer edition with drm. I haven't tested if the pbo files work with this site's ARMA CWA.

PC gaming wiki describes what to do:
