That's quite the creative solution to making a Xenomorph easy to develop in this game.
"Hey y'all, let's use Baraka!"
Pretty arbitrary lol, but I can see why they'd want to use a humanoid model, it'll eliminate a lot of work on trying to retool the model for the fatalities, plus they may not have the technical skill to animate a Xenomorph in a way that properly represents the creature in the first place.
I'm a bit disappointed that we don't get to see a massive feral alien leaping about, gnashing it's teeth, and lashing with its tail though. I'm sure this Xeno-Baraka will have some semblance of that, but not sure if it'll feel the same.
I suppose I should just wait and see before making any hard judgements, but I still do think it was pretty arbitrary--should've just added Baraka instead of this weird compromise.
