Some little concept I made while waiting for the Cyberstan campaign to begin, you can find the full post on my ArtStation: [https://www.artstation.com/artwork/2BeeqJ](https://www.artstation.com/artwork/2BeeqJ) 

modeled in Maya, textured in substance painter, and some details were made in Photoshop  
  
wrote a bit of lore for it, here it is:

Once a sprawling center of industry in service of Super Earth, Cyberstan has now become the most fortified stronghold for the socialist Automatons. Its atmosphere contaminated with an eternal cloud of fumes that bloat out most of the light from its parent star, and its surface reshaped into a planet-sized motherboard, devoid of any biological life.  
As a part of its vast in-depth defenses, lays the Orbital Counter-Battery Network, making use of the stolen Super Earth railways in the planet, these giant tracked cannons can keep at bay any Super Destroyer in low-orbit with it's 560mm energy cannon. These socialist monstrosities are always well guarded by a compliment of Gun Wagons and Point Defense Weapons, rendering most Orbital and Eagle Stratagems ineffective. SEAF doctrine dictates the use of Anti Tank weaponry to target the front locomotive, and gun emplacements, allowing for the deployment of a Hellbomb, although, multiple after-battle reports show a tendency for Helldiver forces mounted in FRVs, rushing full speed into the line of fire with a Portable Hellbomb attached. Results have been varied.

  
and yeah, those are cringe bunker turrets on the wagons
