This is a mobile city that I created and yes, was inspired by mortal engines. The concept is that Arachnis has invaded earth and imagine the Matrix, but with alien spiders and Swarm Nodes everywhere. The last of the humans reside in Quadrant 3 and are trying to overtake her scourge and reclaim what they can.
People have also mentioned it reminds them of something from WarHammer 40k.
Here's a quick video of the build.

Holy amazeballs this is incredible! Despite the look not being appealing to me, its very impressive!
I understand that wholeheartedly. Some people think this build should reside in a museum or an art show due to it's stature.
