Crossplay continues with the launch of Call of Duty®: Modern Warfare® II, allowing players on all platforms to play together.
Along with this unified playing experience, crossplay enables cross-progression, which means your progression in Modern Warfare II will carry over across all platforms linked to the same Activision account, regardless of console generation.
On top of that, gameplay in Modern Warfare II’s Multiplayer and Special Ops – as well as in Call of Duty®: Warzone™ 2.0 – will count toward your overall player progression and Battle Pass progression.
Essentially, whenever you play Multiplayer or Special Ops in Modern Warfare II or Warzone 2.0, you'll unlock something new or at least progress toward it. And that doesn't even include the rewards available during the seasonal Battle Pass system, another way to earn content starting in Season 01.
