The first season of Call of Duty: Modern Warfare 3 (2023) introduces a brand-new act to the story missions of Modern Warfare Zombies - Contact. In this new act, players will continue to explore the ties between the current MWZ story and the events 40 years prior, unfolding through the Zombies modes of Call of Duty: Black Ops Cold War. After completing the Defeat Zakhaev mission at the end of Act 3 - Confrontation, players will receive a small cutscene showing a dark aether portal appearing, attempting to draw Dr. Jansen into the aether, before the ghostly image of a girl in a white dress descends from the portal, approaches Dr. Jansen, then disappears just as quickly as the apparition appeared.
