As part of the DLC Pack 4 announcement, Activision has announced a new feature called Party Up Map Access. This allows those with a Season Pass in Call of Duty: WWII to let their friends that don’t have a Season Pass to play the new DLC Pack 4 maps.
Not only will Season Pass and Shadow War owners enjoy all this new content, but those who don’t own Shadow War can party up with Season Pass owners and join in on the fun for free from August 28 to October 28. Season Pass owners simply create an in-game Party, act as Party leader, invite friends who do not own Season Pass or Shadow War, and fight together across the brand-new Shadow War Multiplayer maps and War Mode mission.
Season Pass is on currently on sale through August 28 at PlayStation Store! Whether you already have the Season Pass, are deciding to pick up the DLC pack when it drops or are ready to Party Up with a good friend, we hope you enjoy the Shadow War when it comes out first on August 28 on PS4!
*Party Up feature access will end on or before Oct. 28, 2018 and may be discontinued in Activision’s discretion. Season Pass owner must be Party leader to enable feature.
