Indeed.

Could the moderators provide a working download link for this campaign? Because in the author's version, it doesn't work for me: only one file, "true story," downloads, and the campaign doesn't launch. Thank you in advance.

The file TrueStory.h5c contains 3 h5m files inside. They need to be extracted into the h5c file (so that there are 2 folders, UseeCampaigns and Maps), then it should work. You can put everything in Maps and play them separately, as I did, because there's still something strange about the campaign.

If Florkingold doesn't mind, I'll try to repack the campaign correctly and provide a link. But it will definitely be later this evening, not now, sorry.
