It's commonly theorised that some of The Unknown's lobby voicelines were teasers for future chapter releases. For example:
"I lived in Dungeons, long forgotten" (DND)
"Hunger. Intolerable Hunger!" (Tokyo Ghoul)
What would you have The Unknown say to tease YOUR dream DBD collab?
@BhamCityCouncil I hate your automated phone system why she telling to put in my reference 4 times and then starts talking about something else Iโve had enough I must say
