About this mod
Dive into days filled with camaraderie and seemingly idle moments... only to unravel a dreadful conspiracy concealed within the shadows—where strange blackouts and peculiar occurrences shroud the streets after dark. In other words: Think mid-2000's Sci-Fi Thriller, but with a DDLC coat of paint.
