This issue is about "key bindings" and the folder "config". Every post I have read states that the pc config file is in "ubisoft game launcher / games/ assassins creed chronicles china/acc game/ config.
except there isnt a config folder in there, I have also looked in application data / local/ ubisoft game launcher/. but it isnt in there either. does anyone know where it may be?

Where game files are located seems to vary with where you bought the game and the game version. At

someone mentions the "BaseInput.ini" file in the

Assassin's Creed Chronicles China > Engine > Config folder

while someone at http://steamcommunity.com/app/354380/discussions/0/492378265886396964/
mentions

...Uplay\Assassin's Creed Chronicles China\ACCGame\Config\DefaultInput.ini

Maybe a systemwide search for "BaseInput.ini" or "DefaultInput.ini" would turn up something, but you'd have to be sure the search was set to search the entire computer.
