Donald Mustard may not be the most well-known name in gaming, but he's definitely one of the most influential. For the past seven years he's been the chief creative officer at Epic Games and "Loremaster of Fortnite"—the big hand on the wheel of one of the biggest videogame phenomena of all time. But soon that era will come to an end, as Mustard has announced that he is retiring.

Mustard's first videogame credit, according to Mobygames, is on the 2002 action game Bloodrayne. In 2005 he co-founded Chair Entertainment, the developer of the Xbox shooter Undertow, which was acquired by Epic Games in 2008. Mustard remained as creative director at the studio, helming the development of Shadow Complex and the Infinity Blade mobile games, until 2016 when he became CCO at Epic.
