4 min. “Call of Duty: Warzone 2.0,” the next iteration of Activision’s battle royale “Warzone,” released today with a revamped battle pass system. Instead of the linear progression of Modern Warfare II Multiplayer Free Access starts today, March 16. It'll be available until March 20. As part of the event, everyone can try out the first-ever Call of Duty Raid in Special Ops Raid Episode 01. But if you aren't interested, you can also spend the weekend playing standard modes like Team Deathmatch and Domination. qvtf0Cg.
