Birth of Shadows was updated to version 1.9.10.5 on December 1st, 2015. This update implemented cycling enemy targets using the TAB key. The nearest enemies will be selected before targets further away. Bosses will not be selected until they are vulnerable to avoid accidental damage. TAB cycling should make it easier to use abilities with the mouse. It will also make it possible to use devices like the Steam controller.
In addition, there was an update for version 1.9.10.4 on November 22nd with the following new features:
- Steam players hosting a multiplayer game can now invite a friend to the game
- Steam players can now join a multiplayer game hosted by a friend
