windows only?

You can also use eDuke32 for running Nam on Linux, that is way better than Dosbox ;)

using windows files?

DSICLAIMER: I didn't tested the steps below myself for Nam, so I can't guarantee this will work. But should work.

So, if GOG Linux installer is missing... follow these non trivial steps:

1. Extract game files from GOG installer as described here
2. Download eDuke32 source, compile it and move into a folder called... NAM.
2a. In alternative install DoxBox on Linux and run the game in DosBox.
3. Copy in that folder the NAM.GRP and NAM.RTS files
4. Execute eDuke32 and select NAM

In any case: contact GOG support, as Linux is ACTUALLY listed as a compatible OS they have to comply or refund the item.

Rather a new enough version of innoextract. You also need Wine for Innounp.

Thanks!
I've updated the post above to include the more up to date link.

I will contact support, I want the files for Linux

Thanks!

Edit.

Linux removed

LOL
