You thought I meant Xenomorphs didn’t you? Wrong!
I’m talking about lore expanding, new alien race on a new planet/environment for the predator to hunt. Of course make them like the fireteam but change up their missions, give them a out there kind of design, cool ass alien weapons (balanced to be on the level of FT weapons of course) and gadgets, and dope customisations.
Make them feel similar to the fireteam but different enough to the point they have their own unique stuff that stands them apart.
Of course have them only playable on their own planet sort of how battlefront 2 does it where on some maps you’re a droid or the others you’re a stormtrooper.
After all, the Yautja did hunt more than just humans and xenos. We just very rarely see them. ;)
