Dennis Detwiller

In 2002 he left Seattle for Vancouver to work with Radical Entertainment where he helped develop The Incredible Hulk: Ultimate Destruction, Scarface: The World is Yours and Prototype. In early 2009, he left Radical Entertainment for Hothead Games. In January 2016, he moved to Monte Cook Games as managing editor.

Detwiller and Greg Stolze prepared their game Godlike for publication by Pagan Publishing. As Pagan was winding down, Detwiller took it to his friends Hsin Chen and Aron Anderson, who created the company Hawthorn Hobgoblynn Press (later known as EOS Press) in 2001 to publish the game. After the release of Godlike in 2002 Detwiller founded Arc Dream Publishing with Shane Ivey. Detwiller and Ivey formed Arc Dream Publishing to produce supplements for Godlike, and in 2003 Arc Dream acquired the licensing from Stolze to use his One-Roll Engine (ORE) dice system. He has since worked on Wild Talents, a follow-up to Godlike, and the free horror game NEMESIS. Detwiller and Ivey produced Delta Green: Targets of Opportunity (2010) and also resurrected Pagan's The Unspeakable Oath in 2010. Following a successful kickstarter campaign, Arc Dream publishing announced a new Delta Green game to be released in 2016.

Dennis Detwiller got in touch with John Scott Tynes after seeing an issue of Pagan Publishing's The Unspeakable Oath magazine in 1991. He then started volunteering with the company. When Tynes moved the company to Seattle in the mid-1990s, Detwiller agreed to move with him. Detwiller worked at Pagan as art director where he co-created the Origins Award-winning game Delta Green in 1997 with Tynes and Adam Scott Glancy; Detwiller wrote a series of three chapbooks (1998-2000), and with Tynes and Glancy he expanded the setting in 1999 with Delta Green: Countdown. Detwiller illustrated The Hills Rise Wild!, which also won an Origins Award.
