Call of Duty: Black Ops 6 players are being urged to revisit Modern Warfare 3 after a user discovered that simply playing and leveling up in the latest entry will unlock Battle Pass tokens for last year's Call of Duty. While all of the cosmetic items and weapons earned in Modern Warfare 3 don't carry over to Black Ops 6, it is worth revisiting last year's shooter simply to receive the available COD Points in the Battle Pass, which do transfer between titles.
