LONDON—Britain will block Microsoft’s $69 billion acquisition of “Call of Duty” maker Activision Blizzard over concerns it would hinder competition in cloud gaming, dealing an unexpected blow to the biggest-ever deal in gaming.
The country’s antitrust regulator said on Wednesday that Microsoft’s commitment to offer access to Activision’s multi-billion dollar “Call of Duty” franchise to leading cloud gaming platforms would not effectively remedy its concerns.
