Revealed in December 2014, Bogus Detour was developed by Crackshell after designer Jochum Skoglund added an Easter egg of an enemy from Serious Sam to the studio's previous game, Hammerwatch. Through communication with Roman Ribarić of Serious Sam franchise owner Croteam, Crackshell was allowed the use of Serious Sam assets and later the rights to develop a full game in Serious Sam series. Crackshell initially intended to self-publish Bogus Detour but later partnered with Devolver Digital.
