My assumption is maybe he saw his Star Fox game that he's been working on from his YouTube channel? The only thing close to sci-fi would be the Ooca who have power armored suits and the like, but that's still more Eberron type of fantasy than sci-fi.
There are specific maps for the mod, and there are maps being made to be added to the mod. But the things you mentioned, is there any confusion? Isn't this a fantasy world?
