I think it may have been Scroll of Atankharzim's standalone mission showcasing the subspace effect.Yeah, the file I have is from Sesquipedalian, so it must be.
It was the sample mission provided with Sesquipedalian's Subspace Rift Sathanas mod. You can find it on the Scroll of Atankharzim downloads (http://scroll.hard-light.net/website/downloads.html) page.
I don't think so. I also specifically remember playing a campaign in which at one point you had to protect a science cruiser that is scanning the activity of the Sathanases from Shivan attack. There were 3 Sathanas Juggernauts, 2 Science cruisers, 4 wings of us and a lot of Shivans. I don't remember the campaign however.That's the one I was talking about. I seem to remember it was from FOW but I'm not sure at all.
