The latest patch for Call of Duty: Black Ops 4’s Blackout mode is here, and there isn’t anything too groundbreaking about it. But the mode is getting a few important bug fixes and quality-of-life updates.

Perhaps the biggest change is coming to the mode’s armor, which is going to let a little bit more damage pass through now. While complaints about the mode have been limited, players with armor that’s a little bit too strong has come up a few times from the community.
