I think the robots should be removed , they are to hard and are very frustrating, on fulgora they would be replaced with biters that can jump cliffs, and channel electricity (they still bite, but any damage they do hurts multiple entities). On aquilo, you could add swimming biters, that can tunnel up from under the ice for a suprise attack. This way it feels more like the original, with its biter varients, the robots just feel weird.
