The offlines files of ENDZONE are corrupted. This concerns only the latest addon released in French version.

Please do the necessary.

Thanks

1. How is it corrupt. Won't install? Digital signature is invalid? File truncated?
2. Are you the only one reporting it?
3. How did you download it? Browser? Galaxy?
4. Have you checked to see if the problem is on your end? (checksum comparison)

I have no idea how you've to come to the conclusion that GOG is at fault. It is of course possible, but I have no way of knowing that based on your post.

You might also want to post exactly which files (the filenames) are corrupt so that others can check too, or so staff have more to go on to fix it.

They are only on your end.

Do the necessary on your end.

I just downloaded and installed the game fine. Think it might be on your side.

Offline installers in other languages than English tend to be outdated and broken. GOG should just remove them all as they are not being kept up to date. The solution is to use the English installers and change language in the game.
