Blackout

Audio
- Occlusion
- When players don't have line of sight to another player, some of the sounds those players make are occluded using an audio filter. This filter subtracts some of the lower frequencies (AKA "bass") to help to create a distinction between players who are in very close proximity to other players, but not necessarily in the same structure.
- Changed occlusion levels to prevent situations that could make footsteps nearly inaudible.
- Refactored occlusion code to properly occlude specific materials and buildings that were missing occlusion.
- Terrain now occludes properly.
- Fixed issues with garage doors that kept them from occluding properly when opening and closing them.
- When players don't have line of sight to another player, some of the sounds those players make are occluded using an audio filter. This filter subtracts some of the lower frequencies (AKA "bass") to help to create a distinction between players who are in very close proximity to other players, but not necessarily in the same structure.
- Distances
- Rebalanced the distances at which players can hear first hear someone approaching.
- Unified distances related to certain movement types – for example, sliding should now be heard about the same distance as other player movement sounds.
- Gameplay Modifiers
- Awareness and Dead Silence Perks have been changed accordingly with the new distance settings for footstep audio.
- Directionality
- Lowered the reverb on third-person footsteps, which helps with the player's understanding of the overall location those footsteps are coming from. This is especially true when wearing headphones/playing in stereo and not in 5.1.
- First and Third Person
- Further lowered the first-person footstep volume that players hear themselves make.
- Further lowered volume of teammates' footsteps.
- Decreased first-person weapon audio slightly to balance with third-person weapons heard by others.
- Addressed an issue with first-person splash audio where jumping into water sounded louder than it should.
- Environment
- Lowered volume on the main ambient blend track (the overall sound made by the environment that players always hear, varying by map location and elevation), allowing subtler gameplay cues to be more audible more often, including footsteps.
- Reduced volume and distance that garage doors can be heard from.
- Modified the volume and distances that opening Stashes can be heard from.
Armor Redesign
- Armor Plate Locations
- In enemy Death Stashes after destroying the Armor of an opponent.

- More rarely, on the ground as a lootable item.
- Durability
- Armor durability has been increased, allowing Armor to last longer through an engagement.
- Armor durability indicators have been updated to display individual pips of Armor.
- Damage Mitigation
- The percentage of damage that Armor mitigates has not been changed. As we monitor how these changes to Armor affect gameplay in Blackout, we will continue to evaluate damage mitigation values.

Like most weekly updates for Black Ops 4, this one is full to the brim with new content. On the multiplayer front, Nuketown transitioning to custom games is a pretty big deal, as are the buffs for Firebreak's Purifier and the nerf for the Titan. Fixes for Zombies, on the other hand, pave the way for the first DLC chapter called Dead of the Night.
The main event for update 1.09, however, is Operation Absolute Zero. It introduces a brand-new specialist for multiplayer, additional Zombies content and, perhaps most importantly, an update to the Blackout battle royale map. Starting later today, players will be able to set sail on a reimagined version of Hijacked from Call of Duty: Black Ops II. New gear at the Black Market also includes a brand-new SMG that can be earned via gameplay in the free Contraband stream. In short, Call of Duty: Black Ops 4 is getting into the holiday spirit with one of the biggest updates the game has ever seen.
Call of Duty: Black Ops 4 is available now on PS4, Xbox One and PC. A version of the 1.09 update will go live on Xbox One later today, with PC to follow shortly thereafter.
