All four current Multiplayer maps from Black Ops Pass will be free from 15 to 18 March 2019. During the free access weekend, players will also get double XP in Blackout and Zombies, double Merits in Blackout and double Tier Progression.
Treyarch are once again offering some of the Black Ops Pass content for free. Over the weekend - starting Friday, 15 March and ending on Monday, 18 March 2019, all current Call of Duty Black Ops 4's DLC multiplayer maps will be available to everyone, regardless of whether you own the Pass or not.
The four maps that will automatically unlock to all players when the trial begins at 6:00 PM CET / 10 AM PT include Elevation, Madagascar, Lockup, and Casino.
Furthermore, Treyarch will also boost players on all platforms with double XP in Blackout and Zombies modes, double Merits in Blackout and double Tier Progression allowing you to unlock items on the Black Market much faster.
Along with these additions, the devs also released short patch notes to detail some of the changes that have been implemented in the update.
The patch will address various issues that occurred when using Outrider's Hawk, nerf Purifier's damage over time and range in Blackout, and reduce Reinforced Perk damage mitigation against fire in Blackout.
There are also gameplay improvements to Hellcatraz Gauntlet in Zombies as well as stability improvements in Multiplayer, Blackout and Zombies.
Some of these changes are coming only to PlayStation 4 and Xbox One, with PC to follow at later date. You can check Treyarch Reddit for a detailed description on improvements and additions in the new patch.
Call of Duty Black Ops 4's seasonal event Shamrock and Ave also continues in Multiplayer, Zombies and Blackout exclusively on PS4 and it's gearing up for PC and Xbox One release next week.
The event brings makeover to Blackout map including new lighting, upgraded dynamic grass, green-coloured smoke, and other St. Patrick’s Day-themed changes.
Also, players will get to test their skills in a new mode multiplayer mode Stockpile in which you'll have to bank enemy shamrocks and deposit them at the nearest pot of gold to claim victory.
