The 2020 release for Necromunda began focusing on expansions for the previously established "Core Gangs", with a planned release for each gang. These books include an extensive history of the gang, including relationships with the various guilds of Necromunda as well as relationships with the higher "royal houses" of Necromunda. In addition to the new books, each book would see releases on both the Games Workshop line and the Forgeworld line to allow players to use models specifically made for the new material in the book.
