woe to the conquered
This is an ex-(Imperial Aquila)-parrot!
Thank you OP! I had this for iOS, but needed it still for my Android devices.
Not sure about the Android, but they updated the ios version with the Virulent Strain expansion... enjoying it so far ($1.99)
I'm not certain how to tell, but judging by the Rulebooks, it appears that the Virulent Strain expansion is included.
(Android variant) Game Options > Rulebooks:
"On the Brink: Roles and Events"
"On the Brink: Virulent Strain"
