How to Earn Unlimited Double XP Tokens in Warzone
The trick to unlimited Double XP and Double Weapon XP tokens, as described by YouTuber RatedLive, lies in completing the Games of Summer challenges. Start by loading into the Shooting Range challenge for Double Weapon XP, or the Marksman Challenge for Double XP. Earn a bronze medal in whichever challenge you selected, then leave the game and return to the multiplayer menu to see you've earned the token.
Modern Warfare and Warzone players can then repeat this process as many times as they care to do so. Each bronze medal completion will earn one Double XP Token. As the challenges can be completed quickly and there's no limit to the number of tokens you can stack up, you'll find yourself with a surplus in no time.
