Roger Collum, Total War vice president, confirmed Shogun 2 – Complete Edition was not developed by Creative Assembly and lacked internal quality assurance processes, citing team focus on other projects.
Collum emphasized Creative Assembly does not use generative AI for asset creation but allows AI tools for analysis and prototyping, while investigating the Shogun 2 – Complete Edition situation with external partners.
Mataboo Games is listed as a co-developer on Shogun 2 – Complete Edition's Steam page, though Collum did not name the external partner involved in its development.
