- 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.
