Call of Duty Developers Treyarch has announced a new promo event that comes to Black Ops 4. Multiplayer, Zombies and Blackout modes.
The Promo event will include three different boosts – Double XP and Double Weapon XP in Multiplayer and Zombies and double values in Blackout.
This promo, honored for the holiday season, will begin on December 28 at 10.00 pm PT / 1 PM ET and will be until 11 am. 10.00 PT / 1 PM ET 1 January.  2XP and 2X Weapon XP will give players a great opportunity not only to clean up XP points and levels up in both Zombies and Multiplayer, but also to achieve higher weapons to unlock attachments.
In the case of Blackout, players will earn merits at double speed so they can level up their Echelon ranks and unlock rewards faster, such as new playable characters.
In addition to the announcement of the Level Elevation Protocols, Treyarch has also announced that Zombies in Blackout will be sporting festive hats from December 24th.
While this holiday addition to Zombies will be temporary, a new permanent Zombie spawn will be added to the farm's location on the Blackout map.
Players can have a great deal of fun on the two new Elevation and Madagascar maps, thanks to a Moshpit playlist package that comes to multiplayer.
Furthermore, a new Map Pack Moshpit playlist will be added to Multiplayer so players can take on Hardpoint, Domination, Kill Confirmed and Team Deathmatch on the two latest maps Madagascar and Elevation.
Unfortunately, the two maps are still only available to those who have purchased the Black Ops Pass, so this playlist will not be available to anyone else.
Those who want to buy the Black Ops Pass can do it online for about $ 50, unlock the stock ss for the two new maps, as well as any other exclusive content that Treyarch publishes throughout the year.
