The Modern Warfare Season 4 launch was delayed previously in response to unrest after the death of George Floyd in Minneapolis, Minnesota on May 25.
Activision posted last week on Twitter: "While we all look forward to playing the new seasons of Modern Warfare, Warzone and Call of Duty: Mobile, now is not the time. We are moving the launches of Modern Warfare Season 4 and Call of Duty: Mobile Season 7 to later dates. Right now it’s time for those speaking up for equality, justice and change to be seen and heard. We stand alongside you."
