Ready for some weekend warfare? Starting at 10AM PT on April 3, free-to-play Warzone players can jump into Call of Duty: Modern Warfare Multiplayer for free.

If you haven’t played Modern Warfare Multiplayer, now’s the chance to see what you’ve missed. Experience the world-class gameplay, deep weapon customization, and gritty, photorealistic environments that make Modern Warfare Multiplayer the ultimate online playground.
