Call of Duty: Black Ops II on sale, double XP this weekend

Treyarch and Activision's newest Call of Duty installment is getting a big promotion this weekend on Steam. The game is on sale through Monday for only $40 ($54 for the Digital Deluxe edition). Plus, Black Ops II multiplayer will be free to play all weekend long until Sunday at 1 pm PT. Players will also receive double XP during this time.

If you're not sure of the difference between the regular edition and the Digital Deluxe edition, the latter includes the Nuketown Zombies and Nuketown 2025 bonus maps, weapon camouflage skin, two player card backgrounds, the official soundtrack, and a free download of Call of Duty: World at War — all for only $14 more!

As for double XP and the free weekend, all platforms that the game is available on are eligible to play. It officially starts at 10 am PT, which is just in a couple of hours as of this writing. The free weekend will end on Sunday at 1 pm PT, while gamers will be eligible for double XP until Monday at 10 am PT.

This marks the first time that Call of Duty: Black Ops II has been free to play for the weekend, but it's actually the third time that the game has seen a double XP weekend. Treyarch and Activision held the first double XP weekend back in December, and then later on just last month. So far, it looks like the companies are hosting these types of events once a month, so we may see more double XP weekends coming up throughout the rest of the spring and summer.
