Call of Duty: Black Ops 7 has revolutionized the franchise’s campaign experience with its innovative “Worlds Collide” package and the groundbreaking Endgame mode. If you’ve been wondering what exactly this mysterious download option contains and how the post-campaign content works, you’re in the right place. This comprehensive guide will break down everything you need to know about Black Ops 7’s most ambitious addition yet, from the sprawling Avalon map to the intricate progression systems that keep players coming back for more.
What Exactly Is Worlds Collide in Black Ops 7?
Worlds Collide is more than just a fancy name—it’s the official designation for Black Ops 7’s campaign and Endgame package. When you’re installing the game, you’ll notice three main components: Worlds Collide, Multiplayer, and Zombies. While the latter two are self-explanatory, Worlds Collide represents the game’s narrative and cooperative experience, culminating in the revolutionary Endgame mode that has players buzzing across gaming communities.
Unlike traditional Call of Duty campaigns that end with a final mission and credits, Black Ops 7’s Worlds Collide package introduces a living, breathing post-campaign experience that continues the story while offering unprecedented replayability. This isn’t just an epilogue—it’s an entirely new way to experience the Black Ops universe, blending narrative elements with open-world exploration and progression systems that rival the game’s multiplayer offerings.
The name “Worlds Collide” is particularly fitting when you consider that the Endgame mode brings together locations, characters, and elements from across Black Ops history into one cohesive experience. It’s where past and present collide, creating something entirely new for the franchise.
Unlocking the Endgame: Your Journey Begins
Before you can dive into the Endgame madness, you’ll need to complete the first 11 co-op campaign missions that make up Black Ops 7’s main story. These missions can be played solo or with up to three friends, setting the stage for the larger conflict that awaits in Avalon. Once you’ve seen the credits roll, the real adventure begins.
What’s particularly clever about Treyarch’s design is that only one player in your squad needs to have completed the campaign to unlock Endgame access for everyone. This means you can team up with friends who haven’t finished the story yet, making it easier to experience the content together. The party host simply needs to have unlocked the mode, and they can invite others who are still working through the campaign.
This approach removes barriers to entry while still rewarding players who complete the main story, creating a perfect balance that encourages both story completion and social play. It’s a thoughtful design choice that demonstrates Treyarch’s understanding of how modern gamers prefer to experience content together.
Welcome to Avalon: The Endgame Playground
At the heart of Black Ops 7’s Endgame mode lies Avalon, a massive open-world map that serves as your playground for the post-campaign experience. Avalon isn’t just another Call of Duty map—it’s a sprawling, living environment that combines locations from previous Black Ops games with new areas created specifically for this mode.
The map is divided into four distinct zones, each with increasing difficulty levels and recommended Combat Ratings. This tiered approach ensures that both newcomers and seasoned veterans can find content appropriate to their skill level while providing clear progression paths for those seeking greater challenges.
What makes Avalon truly special is how it incorporates elements from across Black Ops history. You’ll encounter familiar locations from Black Ops 2, Black Ops 4, and even last year’s Black Ops 6, all reimagined and integrated into this new environment. It’s a love letter to long-time fans while still offering fresh experiences for everyone.
The scale of Avalon is impressive—supporting up to 32 players simultaneously across the map, with squads of up to four players working together (or separately) to complete objectives. This creates a dynamic, ever-changing world where you might encounter other players tackling their own missions or join forces to take down particularly challenging targets.
Understanding Combat Rating: Your Power Progression
Central to the Endgame experience is the Combat Rating system, which serves as your primary measure of power and progression in Avalon. Unlike traditional Call of Duty progression, Combat Rating is session-based, meaning you start fresh each time you enter Avalon but can build up your power throughout a single deployment.
Your Combat Rating increases as you complete objectives, discover intel, and defeat enemies throughout Avalon. Each level up (to a maximum of 60) grants you the opportunity to choose from two different Skills, allowing you to customize your approach to the challenges ahead. These Skills are organized into six distinct Skill Tracks, each catering to different playstyles:
Gunner Skill Track
Perfect for players who love weapon mastery, the Gunner track enhances your firepower with improvements to reload speed, weapon handling, and accuracy. Key abilities include:
- Reload Speed: Faster reloads keep you in the fight longer
- Fast Replate: Quick armor recovery during combat
- Ammo Auto-Refill: Magazines gradually refill over time
- Shocking Reload: Reloading creates an electric discharge that stuns nearby enemies
Surgeon Skill Track
For those who prioritize survival and team support, the Surgeon track focuses on healing, reviving, and staying alive in tough situations:
- Healthy Recovery: Health regeneration starts sooner
- Fast Revive: Quicker revival of teammates with temporary bonuses
- Off the Floor: Eliminating enemies while downed can revive you
- Last Stand Fighter: Extended downed state with improved capabilities
Daredevil Skill Track
If movement is your weapon of choice, the Daredevil track enhances your mobility and traversal abilities:
- Dive Bomber: Diving with your wingsuit creates concussive blasts
- Wingsuit Glider: Improved aerial maneuverability
- Super Slider: Enhanced sliding distance and speed
- Slide Explosions: Create explosions when sliding or diving
Tactician Skill Track
For players who rely on equipment and tactical thinking, the Tactician track maximizes your gadget effectiveness:
- Equipment Hound: Increased equipment ammo capacity
- Quick Deploy: Faster equipment deployment with improved mobility
- Recharger: Reduced cooldowns for equipment and abilities
- Piñata: Chance to spawn live equipment when eliminating enemies
Berserker Skill Track
Aggressive players will love the Berserker track, which rewards chain kills and high-risk play:
- Fast Weapon Fire: Increased rate of fire for all weapons
- Kills Regen Armor: Eliminating enemies restores armor plates
- Crit Chain Speed Boost: Consecutive critical hits grant temporary speed
- Fall Explosions: Create explosions when landing from heights
Bulldozer Skill Track
For those who prefer to be walking tanks, the Bulldozer track enhances durability and close-quarters combat:
- Armor Regen: Automatically regenerate armor plates when damaged
- Point Blank: Increased damage at close range
- Adrenaline Rush: Bonus damage when health is low
- Revival Protection: Reduced damage after being revived
The beauty of this system is that you can mix and match Skills from different tracks as you level up, creating truly unique builds that suit your preferred playstyle. Whether you want to be a fast-moving Daredevil with some Surgeon support capabilities or a heavy-hitting Bulldozer with Tactician utility, the choice is yours.
Operator Abilities: Your Tactical Toolkit
Beyond the Skill Tracks, Black Ops 7’s Endgame mode introduces a sophisticated ability system that further customizes your approach to combat. Each Operator can equip one Major Ability and one Minor Ability, creating countless combinations for different tactical situations.
Major Abilities: Game-Changing Powers
Major Abilities are your most powerful tools, each with significant impact on the battlefield:
- Ballistic Shell: Deploy an energy shield that blocks incoming enemy fire, perfect for reviving teammates or holding positions against overwhelming odds.
- Active Camo: Become nearly invisible for a short duration, allowing for stealthy approaches or quick escapes from dangerous situations. Be careful—gunfire will reveal your position.
- Hand Cannon: Wield a powerful high-damage handgun that’s accurate at range, excellent for eliminating high-value targets from a safe distance.
- Crash Cart: Instantly revive downed squadmates within range and provide temporary invulnerability. Can even be used to self-revive when downed.
- Vision Pulse: Send out a pulse that visually tags enemies through walls for your squad. Tagged enemies also take increased damage, making this invaluable for coordinated attacks.
- War Machine: Unleash a powerful single-shot grenade launcher with a large explosion radius, perfect for clearing groups of enemies or destroying objectives.
- Shadow Break: Create an energy warping field that teleports and damages enemies, creating chaos in enemy formations and providing crowd control.
- Drone Pod: Deploy a device that launches aerial drones that seek out enemies and explode, providing automated fire support and area denial.
Minor Abilities: Tactical Support
Minor Abilities may be less powerful than their Major counterparts, but they’re no less important for your survival and success:
- Grappling Hook: Grapple to surfaces to escape danger or reach new heights, adding verticality to your movement options.
- Portal Grenade: Spawn hallucinations to target and confuse enemies, creating opportunities for flanking or escape.
- Kinetic Jump: Jump to extreme heights, with the option to hold for even higher elevation. Landing stuns nearby enemies, making it useful for both traversal and combat.
- Flicker: Quickly teleport a short distance in your facing direction, with the option to hold and pre-aim. Can even pass through enemies for surprise attacks.
- Supply Link: Instantly supply yourself and your squad with ammo, armor, equipment, and a portion of your Major Ability charge, making it invaluable for sustained engagements.
- Black Hat: Hack enemies, equipment, and vehicles, disabling or converting them to fight for you. The ultimate tool for turning the tables on overwhelming forces.
The combination of Major and Minor abilities creates deep tactical gameplay where the right ability pairing can mean the difference between success and failure. Whether you prefer stealth, direct assault, support, or control, there’s an ability combination that suits your style.
The Extraction Economy: Risk vs. Reward
Perhaps the most defining feature of Black Ops 7’s Endgame mode is its extraction-based economy, which creates meaningful stakes for every deployment into Avalon. Unlike traditional Call of Duty modes where death is merely a temporary setback, Endgame introduces real consequences for failure—along with substantial rewards for success.
Here’s how it works: When you deploy into Avalon, you start with a basic loadout consisting of a Main Weapon, Melee Weapon, Field Acquisition (a weapon you’ve previously extracted), and a piece of Field Equipment. As you complete objectives and defeat enemies, you’ll find better weapons, equipment, and resources that you can add to your arsenal.
However, all of these acquired items are at risk. If you’re killed in action, you lose everything you’ve collected during that deployment—except for the XP and Combat Rating levels you’ve earned. This creates a tense, high-stakes experience where every decision matters.
The only way to permanently acquire the loot you’ve found is to successfully exfiltrate from Avalon. Extraction points are scattered throughout the map, and you can attempt to extract at any time. The question is: do you play it safe and extract early with modest gains, or do you push your luck for better rewards, risking everything in the process?
This risk-reward dynamic is further complicated by the match timer. When time runs out, any players still in Avalon lose everything they’ve collected, creating a race against the clock that adds urgency to the experience.
What makes this system particularly compelling is that the loot you successfully extract has real value beyond the Endgame mode. Weapons and equipment brought back from Avalon can be used in subsequent deployments, and the mode is actually the best place to grind for exclusive campaign camos that aren’t available in multiplayer, Zombies, or Warzone.
For the first time in Call of Duty history, campaign content offers full progression parity with other modes, allowing players to level up, earn unique camos, and make Battle Pass progress entirely through the Endgame experience. This is a game-changer for players who prefer PvE content but still want to advance their overall progression.
Squad Dynamics: Playing Together in Avalon
While Black Ops 7’s Endgame mode can be played solo, it truly shines when experienced with a squad. The mode supports up to 32 players simultaneously across Avalon, with squads of up to four players working together to complete objectives and survive the increasingly dangerous zones.
What makes the squad system particularly interesting is its flexibility. Your squad can stick together to tackle challenging objectives as a cohesive unit, or you can split up to cover more ground and complete multiple objectives simultaneously. This creates interesting strategic decisions about when to work together and when to divide your forces.
Communication becomes key as you coordinate movements, call out enemy positions, and time your ability combinations for maximum effect. A well-coordinated squad can accomplish far more than the sum of its parts, especially when combining complementary abilities and Skill Tracks.
For example, imagine a squad with a player using the Crash Cart ability for emergency revives, another with Vision Pulse for enemy tagging, a third with War Machine for crowd control, and a fourth with Supply Link for keeping everyone stocked with ammo and armor. This combination creates a self-sufficient team capable of handling almost any situation Avalon throws at them.
The social aspect of Endgame extends beyond your immediate squad. With 32 players in the world at once, you’ll frequently encounter other squads working on their own objectives. While there’s no direct PvP combat (Endgame is entirely PvE), you can choose to cooperate with other squads to take down particularly challenging targets or complete large-scale objectives that would be impossible for a single squad alone.
This creates a dynamic social environment where cooperation is encouraged but not required, allowing players to engage with others at their own comfort level. It’s a delicate balance that preserves the intensity of the experience while fostering community interaction.
Comparing Endgame to Previous Call of Duty Modes
If you’re familiar with Call of Duty’s history, you might recognize elements of Endgame from previous modes. Indeed, Treyarch has borrowed successful mechanics from across the franchise while adding enough innovation to create something entirely new.
The most obvious comparison is to Modern Warfare 2’s DMZ mode, which also featured extraction mechanics and high-stakes loot collection. However, Endgame improves upon this foundation with deeper progression systems, more sophisticated abilities, and a stronger narrative connection to the campaign.
Similarly, Modern Warfare 3’s Zombies mode introduced open-world PvE gameplay with zones of increasing difficulty. Endgame takes this concept further with the Combat Rating system, more diverse Skill Tracks, and a greater emphasis on squad-based tactics.
What sets Endgame apart from these predecessors is its integration with the campaign narrative. While DMZ and Zombies existed as separate experiences, Endgame is directly tied to the story of Black Ops 7, continuing the narrative after the main campaign concludes. This story connection gives the gameplay additional weight and meaning beyond just collecting loot and leveling up.
Endgame also benefits from being designed specifically for Black Ops 7, allowing Treyarch to tailor the experience to the game’s unique mechanics, movement system, and weapon handling. The result is a mode that feels both familiar and fresh, building upon proven concepts while introducing enough innovation to stand on its own.
The Future of Call of Duty Campaigns
Black Ops 7’s Worlds Collide and Endgame mode represent more than just a new feature—they signal a potential evolution for Call of Duty campaigns moving forward. By creating a post-campaign experience that offers the same depth of progression and replayability as multiplayer, Treyarch has addressed one of the longtime criticisms of Call of Duty campaigns: their limited replay value.
The success of Endgame could pave the way for similar experiences in future Call of Duty titles, potentially changing how we think about campaign content in the franchise. No longer would campaigns be linear, one-and-done experiences, but rather living, evolving worlds that continue to grow and change long after the credits roll.
This approach also benefits players who prefer PvE content but still want to feel like they’re making meaningful progression. For the first time, these players can level up, earn exclusive camos, and advance their Battle Pass entirely through campaign-related content, without ever touching PvP modes.
The implications for the broader gaming industry are significant as well. Call of Duty is one of the biggest gaming franchises in the world, and when it innovates, others tend to follow. We could see more games adopting this “campaign plus” model, where the main story is just the beginning of a larger, ongoing experience.
Tips for New Players Entering Endgame
If you’re new to Black Ops 7’s Endgame mode, the sheer depth of systems and mechanics can be overwhelming. Here are some essential tips to help you get started:
- Start with Lower Zones: Don’t rush into the highest difficulty zones immediately. Spend time in the safer areas to learn the mechanics, build up your Combat Rating, and get comfortable with the extraction system.
- Experiment with Ability Combinations: Try different Major and Minor ability combinations to find what works best for your playstyle. Some pairs complement each other better than others.
- Don’t Get Greedy: It’s tempting to push for one more objective or better loot, but knowing when to extract is crucial. Remember that extracting with something is better than losing everything.
- Focus on One Skill Track First: While it’s tempting to diversify, focusing on one Skill Track initially allows you to unlock more powerful abilities in that tree faster.
- Use Workbenches: When you find Workbenches in Avalon, use them to upgrade your weapon rarity. This significantly increases your damage output and survivability.
- Communicate with Your Squad: If playing with others, communication is key. Coordinate your abilities, call out enemies, and plan your movements together.
- Learn the Map: Take time to explore and learn the layout of Avalon, including extraction points, Workbench locations, and high-value target areas.
- Manage Your Resources: Keep track of your ammo, armor, and equipment. The Supply Link ability can be a lifesaver in extended engagements.
- Watch the Timer: Always be aware of the match timer and plan your extraction accordingly. Don’t wait until the last minute to head for an extraction point.
- Have Fun: Most importantly, remember that Endgame is meant to be enjoyed. Experiment, take risks, and find the playstyle that’s most enjoyable for you.
