We didn't have too many units with abilities, but the ones we did I felt it made sense to coordinate technologically - and these were where the beginnings of our faction designs stemmed from.
What ended up as the Recall Hunter actually started out as a cloaking unit called the Shade, that threw short-ranged sticky bombs. With the cloaking tech I was inspired by cephalopod camouflage, and while we scrapped the cloaking idea the bumpy / organic look ended up carrying through to the rest of this faction's design language.
