Call of Duty: Black Ops 3's free weekend is also a double XP event
Call of Duty: Black Ops 3 will be flooded with new players over the free weekend, so why not rack up some XP while you're showing them how to play?
You've got until Monday to take advantage of the double XP, which will apply across standard multiplayer modes as well as zombie mode.
This means that if you try the game over the free weekend and enjoy it (which you honestly might, because this is a particularly fun Call of Duty), you can unlock some of the better weapons a bit faster than usual.
If you're waiting for the next Call of Duty before you jump back in, Infinity Ward's Call of Duty: Infinite Warfare is due November 4.
