Square Enix has announced several "strategic changes" to its Western business, including the promotion of Crystal Dynamics boss Darrell Gallagher.
Gallagher will now take up the position of head of studios and oversee all Square Enix developers in North America and Europe, while continuing to retain his Crystal Dynamics role for the "immediate future".
David Anfossi, who previous acted as exec producer on Deus Ex: Human Revolution, has been promoted to studio head of Eidos Montreal.
Anfossi will lead the studio as it completes development of Thief and continues to work on two other unannounced projects, Square Enix said.
At IO Interactive, Rockstar veteran Hannes Seifert has been appointed full time studio head and is overseeing development of "a new AAA Hitman project".
Earlier this week the Danish studio confirmed "significant changes" at the company, resulting in canned projects and layoffs impacting "almost half" of its employees.
Finally, at Square Enix Montréal, Far Cry 3 exec producer Patrick Naud will take on "a central leadership role" as the studio continues to focus on smart devices and games around the Hitman brand.
Phil Rogers, CEO of Square Enix America & Europe, said of the changes: "Our focus remains firmly set on making great games and delivering unforgettable experiences.
"Whilst our games will come in different shapes and sizes, we want to deliver them faster and better and we believe these changes will help our studios achieve just that."
