Black Ops 7: Mystery Solved
“Worlds Collide” is actually the installation package name for Black Ops 7’s co-op campaign and its groundbreaking Endgame mode. According to Activision sources, the name was an outdated internal working title that accidentally made it into the pre-load files before being quietly renamed to “Co-Op Campaign” in a recent update.
The package contains 11 story-driven campaign missions designed for up to four players, followed by access to Avalon—a massive open-world PvE experience that continues the narrative after campaign completion.

Understanding Endgame Mode
Once you complete the campaign’s 11 missions, you’ll unlock Avalon—a war-torn Mediterranean city serving as the setting for Endgame. This isn’t traditional Call of Duty gameplay. Think extraction shooters like Escape from Tarkov meets Destiny 2’s patrol zones.
Players deploy into Avalon solo or in squads to complete dynamic objectives, battle enemy forces including The Guild’s robotic soldiers, and investigate exposure zones leaking mysterious toxins. The catch? You must successfully extract via VTOL to keep your loot and progress. Fail to exfil, and you lose everything except XP and levels earned.
The Four Zones of Avalon
Avalon divides into four difficulty regions, each with recommended Combat Ratings:
Zone 1 (Combat Rating 0): Features landmarks like Cliff Town and Water Treatment—perfect for beginners building their operators’ capabilities.
Zone 2 (Combat Rating 10): Includes Excavation Site and Heliport with moderate challenges and better rewards.
Zone 3 (Combat Rating 30): Contains Winery and Casino areas where elite enemies guard valuable intel and equipment.
Zone 4 (Combat Rating 45): The endgame’s ultimate test featuring Firing Range and Fort—where the greatest secrets and dangers await.
These zones incorporate reimagined locations from Black Ops multiplayer history, creating nostalgic moments for longtime fans while offering fresh PvE experiences.
Why It Matters for Replayability
Treyarch designed Endgame specifically to keep players engaged beyond the campaign’s initial playthrough. Every deployment into Avalon generates different objectives and encounters, ensuring no two runs feel identical.
The progression system rewards dedication. Players unlock Major Abilities like Ballistic Shield (energy barrier), Active Camo (temporary invisibility), Hand Cannon (devastating sidearm), and Crash Cart (team revival). Combat Rating permanently boosts your operator’s Health, Armor, Movement Speed, and Damage—maxing out at level 60.
For those who prefer avoiding Call of Duty’s competitive multiplayer or the intensity of Zombies mode, Endgame offers a complete alternative progression path earning weapon XP, camo unlocks, and Battle Pass tiers through pure PvE gameplay.
Do You Need It?
If you’re strictly interested in Multiplayer and Zombies, you can skip the Worlds Collide download entirely. However, the 74GB investment unlocks substantial content that Activision plans to support post-launch with regular updates.
Squad coordination matters here. While one player in your group needs campaign completion to host Endgame sessions, everyone can participate regardless of their story progress—lowering the barrier for friend groups.
What Makes This Different
Traditional Call of Duty campaigns typically offer linear, one-and-done experiences. Endgame transforms that model into something resembling looter-shooters or extraction games, dramatically extending the campaign’s value proposition.
The risk-reward extraction mechanic creates genuine tension. Pushing deeper into Avalon’s dangerous zones promises better loot but increases your chances of failure. Successfully extracting with high-tier equipment feels genuinely rewarding.

The Bottom Line
“Worlds Collide” represented an accidental glimpse behind Activision’s development curtain—a working title for what became the Co-Op Campaign package. While the name has been updated, the content remains one of Black Ops 7’s most ambitious experiments.
Whether this Endgame model becomes a franchise staple or a one-time experiment depends entirely on player reception. If successful, it could fundamentally change how future Call of Duty campaigns approach replayability.
Frequently Asked Questions
Q: Can I play Black Ops 7 Endgame mode solo or do I need a full squad?
A: You can absolutely play Endgame solo, though Avalon supports up to 32 total players divided into squads of four. Solo players face the same challenges but miss out on squad synergies from combined abilities. The mode scales for 1-4 player squads, letting you play with friends or tackle objectives independently before extracting.
Q: What happens if I fail to extract in Endgame mode?
A: Failing extraction means losing all loot, equipment, and Combat Rating progress earned during that specific Avalon deployment. However, you retain all XP, weapon levels, and operator progression gained during the run. Think of it like extraction shooters—successful exfil secures your rewards, while failure forces you to rebuild your loadout from scratch on the next deployment.
