If you are playing Call of Duty: Advanced Warfare this weekend, you will be gaining Double XP. Same with Battlefield Hardline if you are a Premium customer.
The Double XP weekend kicked off for both games yesterday, and will end on Monday morning.
Both shooters have DLC on the horizon. Advanced Warfare's Supremacy comes with four new maps and another entry in the Exo Zombies Saga. It will be made available first on Xbox Live for $14.99 on June 2.
Battlefield Hardline's Criminal Activity is without a formal release date, but it will be made available sometime in June. Premium members will get to play it first.
