How it works Edit
- Log in to Xbox Live/PlayStation Network.
- Activate your gamer ID in multiplayer mode in Call of Duty: Modern Warfare 3.
- After you activate your gamer ID, log out of Xbox Live/PlayStation Network.
- Log into or register at www.DEWXP.com and enter the codes.
- Click the apply gamer ID button, check the double xp time you want to use, enter your gamer ID and hit apply double xp time.
- Log back into Xbox Live/PlayStation Network. Enter mode to see if your double XP time has been delivered.
- There should be a gold XP icon by it in the barracks if double XP is active. There should also be a timer with a gold XP icon showing the double XP time you have.
If you want to redeem more codes or apply for additional double XP Time to your gamer ID, repeat steps 4 Through 7.
