The "Attack on Titan" animation will be completed in November 2023. Recently, when some netizens were watching the animation, they discovered that a screenshot of a game appeared in the background painting of a certain scene. Foreign Reddit forum user Sotarnicus discovered that the painting on the wall is from the strategy game "Total War: Empire". It seems that the production staff only changed the color tone of the screenshot and used it without any other modifications.
At present, we don’t know whether the animation producer of “Attack on Titan” owns the copyright.
