Dustin "Bloatoid" Twilley (often misspelled as Twiley) is a well known mapper for Blood, and author of Inherit the Earth (1999), Hostile Takeover (2001), and Death Wish (2011, 2017-2020). Death Wish holds the distinction of being one of the most ambitious custom add-ons for Blood ever made, and alongside Twilley's earlier work it represents one of the most extensive collections of any Blood mapper. Since 2013 he has been working on games professionally at Ghost Crab Games with Chris Hoopes on Drive To Hell and currently Hastilude.
