Blizzard co-founder Mike Morhaime will complete his departure in just a few months time.
It was revealed back in October that he was stepping down from his role as president of Blizzard Entertainment, but would remain involved with the firm in an advisory capacity.
This appears to have been a six-month agreement as a securities exchange filing reveals that Morhaime's "employment with the company as a strategic advisor will conclude on April 7, 2019."
This will effectively end Morhaime's involvement in Blizzard, 28 years after he co-founded the Warcraft firm.
He was replaced in October by former executive producer J. Allen Brack, who continues to serve as president.
Activision Blizzard has made several changes to its top-level management in the past few months, naming three new divisional presidents for its Activision, King and Emerging Business units earlier this week.
The publisher has also lost two chief financial officers since the year began, with former Blizzard CFO Amrita Ahuja departing for payment solutions firm Square Inc.
Meanwhile, Activision CFO Spencer Neumann's employment was terminated, with Neumann since resurfacing in the same role at Netflix.
