Cut Content/Call of Duty: Black Ops 4

During the development of Call of Duty: Black Ops 4, many features were cut, including the planned Career mode along with the original vision for Multiplayer. The time period also underwent last-minute changes, becoming a 2040s prequel instead of a sequel to Call of Duty: Black Ops III. Several weapons, game modes, Zombies maps, and other mechanics were also discarded during the development phase.
==Campaign==
===Career Mode===
Career is a scrapped mode that would've replaced the traditional Campaign mode.https://www.eurogamer.net/articles/2018-04-18-sources-call-of-duty-black-ops-4-doesnt-have-a-single-player-campaign It featured a two-versus-two multiplayer mechanic where opposing factions, the Free People's Army and World United Nations, fought to complete asymmetrical objectives whilst gunning down AI in a globe-trotting story with a dynamically changing narrative path. 
Despite an attempt to rework the work done on Career into a more traditional single-player story, the entire campaign was cut in February 2018 and replaced with the Blackout mode. Many assets such as vehicles, character models and locations were reused in the final game.https://kotaku.com/the-human-cost-of-call-of-duty-black-ops-4-1835859016 
==Specialist Stories==
===Specialist War Stories===
After the Career mode was scrapped, Treyarch and Raven Software started development on a new singleplayer campaign set during the 2050s, internally called Specialist War Stories. Despite numerous missions and gameplay prototypes being created between February and May 2018, the mode was also cancelled. 
Specialist War Stories would've explored the backstories of each Multiplayer Specialist, allowing you to experience each mission with their respective weaponry and equipment. Several narrative elements and story locations from Career were reused for the story, including missions in Colombia, Iceland, Australia, Singapore, Cairo and several others. It's believed there was a mission developed for at least every Specialist character. 
Mission 	Image	Description
Outback Roadhouse	 	Set within the Australian outback. During the mission, Battery would ambush a caravan that was holding Torque hostage.https://www.artstation.com/artwork/rR6NJJ
Vengeance 	 	Set within Singapore. Little is known about the mission, only that it would've featured Seraph.https://www.artstation.com/artwork/qADmQ2
==Specialist HQ==
===Cutscene===
The intro cinematic to Specialist HQ originally had a combat segment set within a Shanty Town, however it was cut entirely.https://aladinodebert.com/portfolio/call-of-duty-black-ops-4-cut-scene-intro/ Additionally, there was meant to be story cutscenes including "laser targeting sequences"; however nothing else is known about their planned appearance.

===Breaker Prototype===
Breaker was a tutorial mission prototype set on Seaside and featuring Ajax, focused on finding the Aquilus CEO in a counter-terrorist scenario. The level had civilians running around, and hostages who needed to be rescued with the help of local law enforcement.https://youtu.be/w0b3mUeS6mw 
The prototype was created in March 2018 by Drew Goheen, who worked at Raven Software as a Senior Visual Effects Artist. He described the prototype as "a 'Hero' scenario focused map that would showcase specific hero classes and their unique abilities."https://www.drewgoheen.com/ravenmenu

=== Onboarding Missions ===
Onboarding Missions were small experiences that served as a tutorial for each Specialist in Multiplayer, but were scrapped entirely and replaced by the current Specialist HQ tutorials in mid 2018. 
Their existence can be proven through datamined audio files and leftover scripts. Note the narration by Savannah Mason, which wasn't present in earlier prototypes such as Breaker. 
Specialist	Audio	Description
Nomad 	 	During the mission, Nomad would've needed to steal critical data from three terminals.
Recon 	 	During the mission, Recon would've needed to track down a rogue asset who has defected to the enemy side.
Ruin 	 	During the mission, Ruin would've needed to use his Grav Slam to destroy military stockpiles of microchips.
==General==

Many primary and secondary weapons were cut from the game, some potentially being placeholders.

===Folding Stock===
An icon featuring what appears to be the KN-57 with a foldable stock can be found in the game files. It's unknown if it would've been an attachment or an in-game option. Note that the KN-57's model does have a built-in folding stock, however it remains cosmetic in-game. 
===Mastercrafts===
Four scrapped Mastercraft Variants have remnants in the final game, still being able to be equipped. All of the weapons except the Paladin HB50 are identical to their base counterpart. According to menu descriptions, all of them were planned to be obtained through Blackjack's Shop and would've had visual changes based on kills.

</tabber>
===Game Modes ===
Many game modes were scrapped during development. Game modes such as Infiltration, Payload and Stronghold were originally created for testing individual objectives for the War Mode, however they were still considered for stand-alone inclusion. 
Gamemode 	Icon	Description
Demolition 	 	Remains in game files along with Hardcore variation. Crashes the game on load.
Escalation Game	 	Players start with a Pistol and must gather Specialist Weapons from the ground, which are stored on the HUD. When killed, the held Specialist Weapon is dropped, losing a score point. Held Specialist Weapons can also be burned, losing a point. Gain the most score by eliminating enemies to win.
Frontline 	 	Both teams always spawn at their base and must use teamwork to eliminate players on the opposing team. The first team to reach the score limit wins.
Hostage 	 	Only mentioned within code strings as Hostage. No other information is known.

War Mode 	 	War from Call of Duty: WWII was planned to return, but was scrapped during development. Several maps were created for the mode before it's cancellation.
===Blackjack Specialist===
The character Blackjack was originally a Specialist and was featured in several early 2017 builds. Blackjack was going to be a Slayer, and early 2016 builds reveal Blackjack had Traits such as increased reserve ammo and reduced flinch. 
===Escalation===
Escalation was a gameplay mechanic that allowed every Specialist to progressively become stronger throughout a match. By earning score through objectives and EKIA, the Escalation meter would increase over time, upgrading to new levels and unlocking several progressive perks.
Escalation had five levels with a variety of unlocks, such as increasing health and firepower, along with enhancements such as the Thrust Pack. It's believed the Escalation meter didn't reset on death, and that Escalation upgrades were tied to your Specialist's role. The mechanic was scrapped in early 2018 after playtester feedback.https://insider-gaming.com/black-ops-4-troubled-multiplayer-development/
====Escalation Wheel====
thumb|Escalation Wheel from a 2016 build, playing War on Valencia as Blackjack.
An earlier iteration of the Escalation system featured a wheel of Specialist-tied abilities and weapons that could be customized in your loadout. Instead of earning progressive perks by leveling up the Escalation meter, the player would earn Tokens to unlock single-use items with the wheel. 
The Escalation Wheel was created for the War Mode but was replaced by the dynamic Escalation system in early 2017, with abilities and equipment being tied to a cooldown rather than an unlock. 
===Position Roles===
Position Roles would've gave each Specialist a role that granted an exclusive passive ability and dictated the weaponry and equipment in their Loadout. The confirmed roles of each Specialist character can be found within the script mp_charater_customization. 
Position 	Icon	Description
Slayer 	 	Slayer Specialists could unlock the Thrust Pack through Escalation. Includes Blackjack, Ruin, Seraph and Spectre.
Objective	 	Objective Specialists could capture and decay objectives faster. Includes Ajax, Battery, Prophet and Reaper.
Support 	 	Support Specialists could create a Forward Spawn. Includes Nomad, Firebreak, Recon, Torque, Outrider, and Crash.
===Loadouts===
Loadouts were the original Create-A-Class system before being scrapped and replaced by the Pick Ten System in early 2018. Each Specialist had customizable Loadouts connected to them, including Primary and Secondary Weapons, Attachments, Equipment and Gear. 
The available weaponry and equipment was exclusive to individual Specialists and Position Roles - for example, only Ruin could equip the Grapple Gun in his Loadout, and only Slayer specialists coup equip the Rampart 17. 
====Role Exclusive Weapons====
Each Specialist Role had exclusive weaponry alongside universal weapons. Note the full list of weapons is unknown, and that some weapons may have changed roles during development. <tabber>

===Specialist Ultimates===
The Specialist system originally included an Ultimate ability on a score/time system. After feedback from playtesters, Treyarch decided to scrap the Ultimates entirely and implement Scorestreaks. 
The Ultimate would've been activated by holding down the "swap weapon" button on console, which would be reused for the Scorestreak controls. The original UI can be seen in several pre-release images, with the healing ability being next to the Specialist portrait. In the final game, the Specialist Weapon charges similarly to the Ultimate. <tabber>

Three Perks have internal remnants, including Reveal, which appeared in the May 17th build during the official reveal of Black Ops 4. 
Name 	Internal 	Icon	Description
Drifter 	talent_drifter 	 	Script files suggest it was similar to Awareness.
Extra Equipment	talent_extraequipment	 	Take a second equipment charge.
Reveal 	talent_reveal 	 	heavily increased the Fog of War reveal radius around the user and their teammates. Reveal was replaced by Team Link.
===Thrust Pack===
The Thrust Pack, internally called gear_thrustpack, would've been exclusive Gear for the Specialist Crash in the original Loadout system. The Thrust Pack would've also been accessible to Slayer specialists such as Ruin and Seraph through the Escalation upgrades. Additionally, strings suggest the final implementation of the Thrust Pack before being scrapped was as a standard Gear available to any Specialist. 
The base code for the Thrust Pack was reused for the Blackout mode Heavy Metal Heroes, meaning it can be reequipped into Multiplayer through modding, albeit with the updated visual/audio effects and extremely boosted stats for Blackout's traversal.

Scorestreak	Icon	Description
Power Core 	 	Only sound files remain. All of the Specialists have finalized voice lines mentioning the Power Core.
Riot Squad 	 	Appears in game files and pre-alpha gameplay. Originally the Ultimate for Ajax, the Scorestreak icon for it still exists within the files. Replaced by the Strike Team.
Tank Robot 	 	Also known as the Mini Quadtank. Originally the Ultimate for Prophet, the Scorestreak icon for it still exists within the files. Replaced by the Mantis.
Wraith 	 	Appears in game files and pre-alpha gameplay. Prophet has leftover temp voice-lines mentioning the Wraith.

===Resistances===
Resistances were static passives that provided Specialists with one or more built-in Perks, granting them statistical resistances to status effects, such as reduced explosive damage or increased stun resistance. It was replaced by Gear. 
The March 2017 build featured six Resistances. Note that Resistances had unique stats per Specialist, allowing for different buffs on the same instance of a Resistance. 
Resistance 	Icon	Description
Blind 	 	Applies resistances against visual and audial impairments.
Damage 	 	Applies resistances against general damage and explosives.
Paralyze 	 	Applies resistances against paralyzing and stun debuffs.
Radiation 	 	Applies resistances against effects such as poison and burning.
Shell Shock	 	Applies resistances against handling distortion and flinch.
Slowed 	 	Applies resistances against slowing and movement hindering effects.
===Traits===
Traits were Specialist-tied passives with neutral, positive or negative perks. Specialists would have several permanent Traits, such as Blackjack having increased reserve ammo and reduced visual flinch. The system was scrapped and replaced by Resistances. 
===Specialities===
"Specialty" is the internal name for passive abilities applied when equipping Perks or using abilities. For example, equipping Lightweight will apply the specialties sprintspeed and fallheight.
Many unused specialities remain in the files that were not present in Call of Duty: Black Ops III, however it's unknown how they would've been implemented. They could've been used for Perks, Specialist Abilities, Gear or upgrades earned through Escalation. 
Speciality 	Internal 	Description
Armor Regen 	specialty_armorregen 	Passively regenerates the Player's armor.
Armor Pickups 	specialty_spawnarmorpickups 	Spawns armor pickups that repair the Player's armor, similar to Scavenger.
Double Jump 	specialty_doublejump 	Enables Thrust Jumping.
Forward Spawn Fast Interact	specialty_forwardspawnfastinteract	Interact with a Forward Spawn faster.
Wall Run 	specialty_wallrun 	Enables Wall Running.
===Sprint Slowdown===
In early builds of Multiplayer, a sprinting meter can be seen. Once the meter is depleted, the Player can still run but at a significantly slower speed. The UI assets for this feature can still be found in the game files, with other scrapped mechanics referring to limited sprint stamina. 
===Mag Dropping===
Feature for Multiplayer that was cut in early 2018. When a Player reloaded their weapon and still had ammo left within a magazine, the ammo would be lost instead of going back into the reserves. Despite the feature being cut, the stylised HUD showing mag icons instead of a reserve ammo count remained in Multiplayer.
===Spawn System===
The original spawn system allowed Players to choose where they wanted to respawn between several locations marked as beacons. These beacons were located at team-owned objectives, and could be selected between alongside Seraph's Tac-Deploy. There were also Forward Spawns that could be constructed at objectives by Support Specialists. 
===Medal===
Cut Medal for eliminating an enemy who is trapped within foam can be found within the files. Meant for the Foam Grenade. 
File:Foam Kill Medal Icon BO4.png|Icon for the Foam Kill medal. 
==Blackout==
===Milovan Hotel===
According to a vista billboard on the map Lockup, the Days of Summer event was going to feature a finished version of the Construction Site, known as Milovan Hotel. The billboard features an in-game render of the updated hotel, with Days of Summer props in their exact locations as the summer-themed event. Despite being teased outside the map, the update didn't feature the finished hotel, only adding the few summer-themed props. 
===Bosses===

===Zombies Map Schedule===
The original DLC plan was to release a Zombies map every Operation. The first season of Black Ops Pass content would feature four premium Chaos Zombies storyline maps and two free Aether Zombies maps.https://www.reddit.com/r/CODZombies/comments/9vx66d/list_of_all_things_callofnobodycares_has_leaked/?rdt=33990
===Maps===
==== Pre-Aether Development (2017) ====
Before the inclusion of Aether storyline content, two planned DLC Zombies maps were scrapped. As listed within an early 2017 content schedule for Black Ops 4, the maps Titanic (ZOD), England (DLC1), Morocco (DLC2) and Russia (DLC3) are mentioned as maps within development. 
Map 	Internal 	Description
Morocco	zm_morocco	Scrapped Chaos storyline map. Morocco would've been DLC2 for the Chaos story, releasing after DLC1 "England" (Dead of the Night).
Russia 	zm_russia 	Scrapped Chaos storyline map. Russia would've been DLC3 for the Chaos story, releasing after Morocco.
==== Post-Aether Development (2018-2019) ====
A Chaos storyline map codenamed zm_blue which was meant to release after Tag der Toten. Files also reveal TranZit, Buried and Origins from Call of Duty: Black Ops II were meant to return for the second season of the Aether storyline. 
Map 	Internal 	Map Index	Description 	Release
Blue 	zm_blue (Console) / p8_zm_blu (Model Source)	47 	Scrapped Chaos storyline map. Datamined model strings reference an "Earth Throne Room Waterfall". Blue would've released after Tag der Toten according to playlist files, and narratively followed from Ancient Evil. Originally planned to release as DLC3 in the Black Ops Pass, the map was delayed to the second pass ("Second Season") before being cancelled, according to Jason Blundell.https://youtu.be/-XFsuYtG7OA?t=2485	Black Ops Pass
Chaos DLC 4	Unknown 	48 	Scrapped Chaos Storyline map. Nothing else is known other than it would've released after zm_blue, and taken the spot of DLC4 in the Black Ops Pass. 	Black Ops Pass
TranZit 	p7_zm_tranzit /p8_zm_tranzit (Model Source) 	 	Scrapped Aether storyline map with hundreds of leftover T8 model strings and textures referencing zm_tra. Additionally, several mechanics for the map, including a "Meteorite Buildable", the Bank, Jetgun and fully implemented Zombie AI for the Bus can be found. TranZit would've narratively taken place after Tag der Toten. 	Black Ops Pass 2
Buried 	p8_zm_bu (Model Source) 	 	Scrapped Aether storyline map with a single leftover T8 model string p8_zm_bu_wood_door_frame. Note the zm_bu prefix, the same used for Buried in Call of Duty: Black Ops II, distinct from the wz_buried prefix used for Ghost Town in Blackout. 	Black Ops Pass 2
Great War 	p8_zm_ori (Model Source) 	 	Scrapped Aether storyline map based around The Great War that would've ended the Aether Story. Unique textures, strings and sound files of Great War Crusader AIs tagged "DLC4" can be found internally. Unused T8 model strings referencing p8_zm_ori (Origins) can also be found. Note that Tag der Toten is not called "DLC4" internally. 	Black Ops Pass 2
===Gamemodes===
Two modes were known to be scrapped, including Grief from Call of Duty: Black Ops II and Treyarch Custom Mutations. 
Gamemode	Internal	Icon	Description
Grief 	zgrief 	 	Four-vs-four competitive gamemode where two teams fought to outlast the other. During gameplay, both sides have opportunities to grief each other.
TCM 	ztcm 	 	Treyarch's Custom Mutations (TCMs) was a planned series of game modes which would've offered specialized sets of Custom Mutations tailored to specific Zombies maps.

===Newtons Cookbook===
Newton's Cookbook was announced for Zombies, but was quietly scrapped for unknown reasons. It would've allowed for the crafting of Elixirs and Talismans. Internal code and menu placements imply the feature was fully functionable before being cut.
===Factions===
Factions would've allowed players to earn seasonal rewards such as calling cards and cosmetics by completing Callings exclusive to their preferred faction. The four primary Factions were known as Bloodfaith, Tempus Novi, Dustborn and The First Legion. It was planned to release for Zombies at launch, but was delayed to Q2 of 2019 before being quietly cancelled.

===Calling Artifacts===
Models for several "Calling Artifacts" can be found internally, connected to the scrapped Factions system. Strings imply being able to discover and possibly inspect several artifacts tied to specific Zombies Factions. There were 13 total collectable Artifacts per Faction.

===Alpha Omega Cutscenes===
In January 2019, Travis Wong, the mocap artist for Diego and Takeo revealed he was doing mocap work for both characters. Due to the timing, it can be presumed the work was for Ancient Evil and Alpha Omega, however the latter map would feature no in-game or cinematic cutscenes.https://www.reddit.com/r/CODZombies/comments/aemnbh/so_the_next_dlc2_will_be_chaos_or_aether_diego_or/?utm_source=amp&utm_medium=&utm_content=post_title
===Old Dempsey===
An asset created by High Moon Studios in early 2019 showcases an older version of Dempsey. It's unknown what the asset would've been used for.

===Perks===
The perks Juggernog and Speed Cola were scrapped in 2018 due to wanting to balance the game and eliminate crutch perks. Widow's Wine was also cut and replaced by Winter's Wail. The reload speed buff was reintroduced post-launch as a bonus ability for purchasing a Modifier perk.

===Death Machine===
The Death Machine power-up can still be loaded under death_machine, which uses the model of Reaper's Scythe. It was likely cut due to the Overkill Special Weapon filling a similar role.

===Narrative Rooms===
Almost every map has an inaccessible room hidden within the level that was originally meant to be accessed. The rooms can still be loaded into the level through modding, internally named lore_room and narrative_room. AI bots still have movement logic for entering these locations. 
The last map to feature a hidden room is Alpha Omega. The hidden room in Blood of the Dead can be accessed within the Alcatraz map in Blackout.

==Customization==
=== Character Customization ===
Remaining script files refer to an in-depth character creation system, likely designed for the Career mode. Additionally, some script files suggest that it may have been planned for reuse in Multiplayer and Zombies. The final game only features Outfit and Warpaint customization globally, selectable icons for certain Specialist Outfits and other custom options for the default "Player" character in Blackout.
