After I posted London Calling on the 2000AD message board, someone suggested a pixel art Mega City One, and here’s the result. I realised that a cityscape would be next to impossible so I settled for a block war. With zombies. And a riot. And the Dark Judges.
This was half the size of the London Calling canvas and so more managable. The blocks were also constructed of 2 or 3 reused assets to speed up the process.
