Wuchang: Fallen Feathers is a third person soulslike action roleplaying game developed by Leenzee. The game's Chinese name is 明末:渊虚之羽 (Míngmò: Yuānxū Zhī Yǔ) which Google translates to something along the lines of "Late Ming Era: Feathers of the Abyss". The first part certainly wouldn't have sounded good in English. 'Wuchang' comes from the (silent) protagonist's name: Bai Wuchang.
