SEATTLE (BLOOMBERG)- Microsoft said it's buying Activision Blizzard in a US$68.7 billion ($92.7 billion) deal, uniting two of the biggest forces in video games.

In its largest purchase ever, Microsoft will pay US$95 a share in cash for one of the US' biggest gaming publishers, known for titles like Call of Duty and World of Warcraft but which is also grappling with a cultural upheaval over its treatment of women.

Activision chief executive Bobby Kotick will continue to serve in that role, Microsoft said. Once the deal closes, the Activision Blizzard business will report to Mr Phil Spencer, who heads Microsoft Gaming.

Adding Activision's stable of popular titles will help Microsoft expand its own offerings for the Xbox console and better compete with rival Sony's PlayStation. Activision has a long history with the Xbox. The publisher's largest franchise, Call of Duty, became successful largely due to Microsoft's innovative online platform Xbox Live, which allows players to connect for multiplayer matches.

Most of Activision's games are published on Xbox consoles. "This acquisition will accelerate the growth in Microsoft's gaming business across mobile, PC, console and cloud and will provide building blocks for the metaverse," Microsoft said in a statement Tuesday.

One of the industry's most legendary publishers, Activision has been mired in controversy for months amid several lawsuits over allegations of gender discrimination and harassment.

Mr Kotick, who has led the company for three decades, has been under pressure from employees to resign. The scandal has taken a toll on a company already struggling to adapt to the end of a pandemic-fueled video game boom.

In November, Activision delayed two of its most anticipated games and gave a sales forecast for the fourth quarter that fell short of Wall Street's expectations, sending the shares plunging.
