Question: how to get call of duty modern warfare battle pass for free?
Answer: In order to claim these, head to the Item Shop and go to the “Just For You” tab. That's where you'll find the 10 Tier Gift. Simply claim it and you'll bump up 10 tiers for both Warzone and Modern Warfare. If you're already at Tier 91-100 the free tiers will apply to the Season 3 Battle Pass.
