This titan armament is also placed deep within Warhammer lore. It is a carapace mounted array system & control platform designed to aid in titan cooperation on the battlefield, but due to the independent nature of titans, this piece is not commonly used. It is also used when titans are equipped with a deathstrike cannon as a replacement command centre for the princepts of the titan when the head is removed to make way for the massive weapon.
Liek titans, so do I, that's why I'm here, to design more parts for warhammer titans. I also sometimes do knight parts. If you have any suggestions feel free to ask me in the messages thingy.
