There’s always something going on in the Call of Duty world, and to get you up to speed, we have the CoD BO6 Season 4 patch notes as well as a full roadmap of new content.

But with Black Ops 6 getting a full showcase at Summer Game Fest 2024, can we expect to see the next Call of Duty getting the same treatment at the upcoming Summer Game Fest 2025? If so, we may be saying bye-bye to Black Ops 6 content in the not-so-distant future.

Still, there’s plenty of duty to be called to in the here and now, especially with big additions to the Zombies mode that sees a fan favourite return from one of the best Black Ops games!

Even so, we can’t help but wonder where the next Call of Duty will take us, but according to Tom Henderson of Insider Gaming, the next instalment may be a direct sequel to Black Ops 2 set in the near future of the 2030s.

It won’t be long until we find out what it could be, however, but as for now, let’s see what the CoD of today has in store for us.

What changes in CoD BO6 Season 4?

Quite a lot, actually! In Call of Duty: Black Ops 6 Season 4, there are new maps, weapons, attachments, Multiplayer modes and more.

A big addition is the return of Grief to Zombies, a mode not seen since Black Ops 2. In Grief, there are two teams of four that compete against each other, on top of the pesky zeds and monsters to take care of.

The new Multiplayer maps are Shutdown, Fugitive and Blitz, which are all set in Iceland. Blitz in particular looks incredible, with the map set on a road in the wake of a prison break, overlooking the beautiful rugged coast.

But there’s far too much to get through here, so check out the patch notes down below!

Full CoD BO6 Season 4 patch notes

The following are most of the relevant patch notes for Call of Duty: Black Ops 6 Season 4, but if you want to check them out in full, you can do so on the official Call of Duty website.

New Multiplayer Maps

Shutdown (6v6)

Shutdown in Black Ops 6. Activision

• Before breaking out Stitch, Adler and team first need to cut off the power to the black site prison, bringing them to a hydroelectric plant built on the rugged volcanic terrain of Iceland. Fight in and around the central building housing the now wrecked Turbine or dive down the Sluice into the Lake, its waters hugging the plant’s south end by the Transformers. Jump up by the red container to target enemies from far out or swim back onshore to reach the Atrium and Parking.

Fugitive (6v6)

Fugitive in Black Ops 6. Activision

• Deploy to a secret CIA black site in a remote part of Iceland, the very location where Stitch has been imprisoned until Adler brings him in as an unlikely ally for an urgent operation. With the power out, Adler and his crew seize their chance to infiltrate the prison, climbing, zipping, and battling their way through the frozen compound.

Blitz (6v6, 2v2)

Blitz in Black Ops 6. Activision

• Traffic comes to a halt as Pantheon reinforcements race toward the prison but get ambushed by the Rogue team. Leave the road and seek out targets over the rugged terrain of the Cliffside or move inland, ambushing enemies at the Waterfall.

New Multiplayer Modes

Team Elimination

• In this twist on Kill Confirmed, two teams are given a limited number of lives each round as they fight to be the last surviving team. Players drop a dog tag on death that can be picked up by the enemy to confirm the kill or by a teammate to deny the opposing team. Survive longer than the other team or hold the most remaining lives when the timer ends to win the round.

New Weapons (Multiplayer & Zombies)

LC10 - SMG (Battle Pass)

• Full-auto submachine gun. Excellent accuracy and range, with a moderate rate of fire. Average mobility and very slow handling for its class.
• Returning after its debut in Call of Duty: Black Ops Cold War, the LC10 SMG spits out rounds fast coupled with good accuracy and range, moderate damage, and a quick reload to get you back into the fight.

FFAR 1 - Assault Rifle (Battle Pass)

• Full-auto assault rifle. Very high rate of fire and excellent CQB power, but slower handling and mobility.
• Boasting a blazing fast fire rate that rivals the SMG weapon class, this bullpup Assault Rifle is designed for taking down targets fast. The somewhat unpredictable recoil favors burst fire when tackling distant targets, but once you’re locked on it’s all over for them.

Essex Model 07 - Marksman Rifle (In-Season, Event Reward)

• Lever-action marksman rifle. High damage potential. Balanced by slower rate of fire and handling.
• Inflict heavy critical point damage with this lever-action tactical rifle. An ideal tool for the new sheriff in town, this classic armament offers smooth handling with shots that quickly recenter after kicking up. Choose from a variety of Levers to further customize the weapon’s action, improving ADS speed, sprint to fire speed, and other movement abilities.

New Attachments

G-Grip (Battle Pass)

• Vertical foregrip with integrated laser for improved firing stability, horizontal recoil control, and tightened spread when transitioning between hipfire and aiming down sights. Beam: Blue. Blocks Laser attachments.
• Available for SMGs (except PP-19) and Assault Rifles

Stryder .22 3-Round Burst Mod (Launch, Event Reward)

• Convert the Stryder .22 into a 3-round burst. Drastically improves fire rate and maintains manageable gun kick but alters the weapon’s damage profile outside of the effective range.

SVD Full Auto Mod (In-Season, Event Reward)

• Convert the SVD from semi-auto to full-auto functionality, ramping up the speed of your damage output and drastically improving recoil and handling.

TR2 CQB Auto Conversion

• Alter the TR2 Marksman Rifle to fire handgun caliber rounds, resulting in a Marksman Rifle with a compact frame and fully automatic capabilities that rival fire rates of an SMG!

New Scorestreak (Multiplayer & Zombies)

Grim Reaper (In-Season)

• Powerful semi-automatic launcher that can fire up to four rockets in one load.
• Wield the Grim Reaper, a quad tube loaded Launcher capable of inflicting heavy damage on enemies. Whether targeting Operators or locking on to enemy Scorestreaks, the Grim Reaper’s payload delivers a huge explosion. The weapon is lost if you’re taken out, so save it for the right moment and bring backup to ensure you have the protection needed to unleash havoc.

Grief Returns to Zombies

Not seen since Black Ops 2, Grief returns to Zombies! This fan-favourite mode pits two teams of four against each other, with both sides vying to out-survive the other. As the battlelines are drawn between S.A.M. and Director Richtofen, each team pledges their support to one of these rivals at the start of a match, subsequently receiving handler comms support from one of them throughout the ensuing chaos.

• 4v4 competitive mode where two teams outwit and outlast each other. Capture zones to debuff enemies. No damage against other players. Respawns every third round.
• Available Maps: Liberty Falls, Terminus, Citadelle des Morts, The Tomb, Shattered Veil.
• Restricted: Wonder Weapons, GobbleGums: Exit Strategy, Idle Eyes, Wonderbar!, Time Out, and Flavor Hex (Season 04 GobbleGum).
• For more details about the return of Grief visit the COD Blog.

New Zombies Challenges

Dark Ops Challenges (Launch)

• A mysterious new set of hidden Calling Cards and bounteous amounts of XP are available at the start of Season 04, thanks to a fresh drop of Zombies Dark Ops Challenges. Who knows... maybe there’s even one for Grief.

New Ammo Mod

Shatter Blast (Launch)

• “Bullets deal explosive damage. Each bullet has a chance to create an explosion that destroys armor.”

• Modify your ammunition to explode the toughened armor of certain normal and Special undead enemies. This mod also has a second benefit, creating an area-of-effect blast radius at the same time, whether any armor is shattered or not.

• Augments

  • Major

    • Big Game

      • Shatter Blast can be used against Elite enemies. Expect an impressively sized explosion.

    • Blast Chain

      • On explosion, three additional explosions occur in rapid succession.

    • Blast Repair

      • For every enemy that has its armor destroyed by Shatter Blast, armor health will be restored for the player.

  • Minor

    • Blast Zone

      • Increase the size of the explosion.

    • Blast Boost

      • Increase the explosion damage.

  • Blast Wave

    • Normal enemies are knocked down by the explosion.

New GobbleGums

Available at Launch, crack your teeth on three new GobbleGums, available across all maps once you earn or unlock them and equip them in your GobbleGum Loadout Pack.

• Explosive Flourish (Epic): Reloading your weapon creates an explosion around you. GobbleGum lasts 2 minutes.
