First, I had an extra servo skull who is carrying four grenades. I imagined it would make for a nasty trap, waiting in the snow for an unsuspecting victim to draw near.
I also have been wanting to build a combat servitor with an antlered head. The skull, designed by Ana Polanšćak, came from a Kickstarter by Harwood Hobbies. The base body is a Sicarian Ruststalker with some zombie scythe arms and a bit of greenstuff.
I picture this frightening servitor as being a remnant of a long forgotten Adeptus Mechanicus WΣNDɨGØ project research station. The AdMech explorator fleets would often lay claim to a world by establishing a small base, populating it with guardian servitors held in stasis, and moving on.
Lastly a few shots that have some Photoshopped snow effects.
