Yesterday, a large update (2.36 GB on iOS) for Bully was released for smartphones and tablets. It introduces Screen Space Ambient Occlusion (SSAO) technology on Android and makes several other changes, as well as fixes dozens of bugs and errors.
Most likely, this is preparation for adding the mobile version to the library of games available through the GTA+ paid subscription. The PC and console versions are already included.
