Not only is Call of Duty: Black Ops 4's Blackout free to try for this week (ending on January 24), it seems that Treyarch are pulling out all the stops to get new players involved by adding a limited time mode which will allow players to respawn—with certain limitations.
A tweet from Treyarch's twitter account late yesterday confirmed that the new mode is now live on PlayStation 4, meaning it will hit PCs in the middle of next week and run until January 30.
