What I'd like to know is... WTF DLC, exactly...
cause, as far as I know of... there never WAS any DLC's (DownLoadable Content) for SH5.
SH5, was in its entirety, just the base game components, alone... that's it.
Unless... they're confusing that crap game saves sync mumbo jumbo, with being DLC material... BUT... even that's a major stretch, at worst.
