Gotta be honest and say it's kinda surprising to see a CEO being the one who leaves the company following such an infamous launch, they often try and retain their position while letting go devs to make up for lost revenue.
Starbreeze in general is a company that's had a rocky history going back to their original founders, and in terms of releases they're also notably inconsistent putting out both well liked games like Enclave, The Chronicles of Riddick: Escape from Butcher Bay, and the first The Darkness game (the sequel was handled by Warframe developer Digital Extremes), but also some infamous games like EA's 2012 Syndicate reboot (which reimagined the classic action strategy series as an early 2010s FPS), 2018's Overkill's The Walking Dead, and now Payday 3.
