The criticized gaming company, which is a merger of gaming giants Activision and Blizzard, is behind games such as World of Warcraft, Call of Duty and Overwatch.
In recent weeks, criticism of the company's culture has been massive.
After a two-year investigation by the California State Department of Fair Employment, with testimonies of how women and other minority groups on Activision Blizzard have been paid less, conditions and subjected to harassment, a lawsuit was filed against the company two weeks ago.
There have also been protests outside the gaming company's headquarters in California and an open letter, signed by more than 800 employees at Activision Blizzard, demanding changes has been published.
Now the Blizzard branch's chief executive, J. Allen Brack, is resigning.
Activision Blizzard writes in a press release on its website that he will be replaced by two people, Jen Oneal and Mike Ybarra.
According to the press release, the two will work to regain the trust of the employees and build the "safest and most welcoming workplace for women, all genders, ethnicities, sexualities and backgrounds".
