With five new prestige ranks to work through in Call of Duty: Ghosts’ Extinction mode, we’re betting you could use a little bit of double XP. So does Infinity Ward.

This weekend the studio is hitting the Extinction double XP switch so you can rank up faster while surviving against hordes of alien invaders. It’s also a good excuse for Xbox Live members to visit the new Extinction Episode 3: Awakening map that launched with the Invasion DLC not too long ago.

The event starts tomorrow, June 6 and goes through to Monday, June 9. It’s also open to everyone on all platforms.
