Eidos Montreal founder and general manager Stephane D'Astous has resigned, stating that he had "irreconcilable" differences with parent company Square Enix.
The studio that brought us the excellent Deus Ex: Human Revolution is currently working on the upcoming Thief reboot as well as two unannounced projects.
"Since last year's financial short-coming performance of Square Enix Europe, we (HQ London and GM Eidos Montreal) have had growing and divergent opinions on what needed to be done to correct the situation," D'Astous said in a statement sent to Develop.
"The lack of leadership, lack of courage and the lack of communication were so evident, that I wasn't able to conduct my job correctly. I realised that our differences were irreconcilable, and that the best decision was unfortunately to part ways."
Deus Ex: Human Revolution executive producer David Anfossi is taking over D'Astous' role as Eidos Montreal head.
Last month a Square Enix spokesperson told Develop that D'Astous had, "taken on a new project in the company working directly with [newly appointed head of studios] Darrell Gallagher across our studios focusing on cross studio operations." It doesn't sound like D'Astous took kindly to his new role.
This is but the latest fallout from Square Enix's £69.87 million restructuring of the company that it began in March following an "extraordinary loss" for the fiscal year. Shortly thereafter Yosuke Matsuda replaced Yochi Wada as Square Enix boss.
The publisher is currently working on Thief, Lightning Returns: Final Fantasy 13, Final Fantasy 10 and 10-2 HD, Final Fantasy 14: A Realm Reborn, and Final Fantasy 15.
