Widowbat.
All rights to Batman: Arkham Knight belong to Warner Bros. Interactive Entertainment.
I make mods as a hobby, but Widowbat was by far the most complex modding project I'd undertaken.
I essentially had to reverse engineer Batman: Arkham Knight to make the character fully functional,
since I had limited community resources to work with.
Based on community reception, I consider the project an absolute success.
