The landscape of the first-person shooter market shifted significantly following Microsoft’s $68.7 billion acquisition of Activision Blizzard, a move that has now led to the veteran Call of Duty publisher taking a central role in the future of the Halo franchise. Frank O’Connor, the former franchise development director who spent nearly two decades shaping the Master Chief’s journey, has publicly offered a strategic roadmap for Activision as it begins the process of assembling a "purpose-built team" for the next installment in the series. O’Connor’s insights, shared via professional networks, arrive at a precarious moment for the franchise, which has seen internal restructuring, a rebranding of its lead studio, and a transition in its core technological foundation.
The Evolution of Halo Leadership and the Shift to Activision
To understand the weight of O’Connor’s advice, one must look at the historical trajectory of the Halo intellectual property. Originally developed by Bungie, the series became the cornerstone of the Xbox brand starting in 2001 with Halo: Combat Evolved. When Bungie split from Microsoft in 2007, 343 Industries was formed specifically to manage the IP, with O’Connor moving from Bungie to 343 to maintain continuity.
However, the decade under 343 Industries was marked by both commercial success and critical division. While Halo 4 and Halo 5: Guardians performed well financially, they faced criticism for moving away from the series’ traditional gameplay mechanics. The most recent entry, Halo Infinite, launched in 2021 after a high-profile year-long delay. Despite a strong initial reception, the game struggled with a slow content cadence and technical limitations stemming from its proprietary Slipspace Engine.
In 2023, Microsoft initiated a massive "reset" of the franchise. This included rebranding 343 Industries as Halo Studios and announcing a shift to Epic Games’ Unreal Engine 5. Amidst these changes, O’Connor departed the company. The subsequent integration of Activision into the Microsoft gaming ecosystem has provided a new opportunity: leveraging the production efficiency and live-service expertise of the teams behind Call of Duty to revitalize the Master Chief.
Three Strategic Paths for the Future of Halo
O’Connor identifies three distinct directions Activision could take with the next Halo project. He notes that none of these paths are "easy, guaranteed, or necessarily viable," highlighting the inherent difficulty in managing a legacy IP with a passionate and often fractured fanbase.
The Traditionalist Approach: Scaling the Classic Sandbox
The first path involves a return to the "classic" Halo experience. This would focus on the series’ unique "golden triangle" of gameplay—the balance between firearms, grenades, and melee combat—set within a chaotic, physics-driven sandbox. O’Connor suggests that a game tailored to the core audience but scaled for modern accessibility could regain the series’ former dominance.

The "classic" feel of Halo is defined by its lower movement speed relative to modern "twitch" shooters and its emphasis on map control and vehicle play. By modernizing the presentation while retaining the "heavy" feel of the Spartan armor and the unpredictability of the AI, Activision could appeal to the millions of players who grew up with the original trilogy. O’Connor emphasizes that a larger player base is a "mathematical default" for a better multiplayer experience, suggesting that the next game must be built to sustain a massive, healthy population from day one.
The Innovation Approach: Reimagining the Universe
The second path O’Connor suggests is a radical departure from established norms. This would involve "reinventing the game/universe in a surprising but fantastic way." This could manifest as a genre shift—perhaps moving from a traditional FPS to an Action-RPG (ARPG) or a tactical shooter.
This path is the most controversial among fans, as it flirts with the idea of a lore reboot. Recent rumors of a potential reboot were met with significant pushback from the community, who are deeply invested in the twenty-year narrative of the Covenant War and the Forerunner legacy. However, O’Connor argues that a "small head start based on curiosity or loyalty" could give such a project the momentum needed to establish a new era for the franchise, provided the quality is undeniable.
The Commercial Approach: The "Call of Halo" Model
The third path is perhaps the most logical from a business perspective, given Activision’s pedigree. This involves translating the Halo IP into the "Activision comfort zone." This would mean adopting the player progression systems, seasonal content structures, and monetization models that have made Call of Duty a multi-billion-dollar annual powerhouse.
Under this model, Halo would likely move away from its traditional "once-every-six-years" release cycle in favor of more frequent, high-spectacle releases and a robust, constant content stream. This would align the franchise with modern industry standards for live-service games, ensuring that players always have new maps, modes, and cosmetics to engage with. While this might alienate some "old-school" fans, it would provide the financial stability and player retention that Halo Infinite struggled to maintain.
Addressing the Human Element: Talent and Retention
Beyond gameplay mechanics and business models, O’Connor’s most poignant advice concerns the people behind the code. He explicitly urges Activision to hire former employees from Bungie and Halo Studios (343) who were affected by the recent wave of industry-wide layoffs.
The gaming industry saw nearly 10,000 layoffs in 2023, with 2024 already on track to exceed that number. Microsoft itself cut approximately 1,900 positions across its gaming divisions earlier this year. O’Connor suggests that these "laid off folk" are "bursting with talent and ideas that got nerfed or shut down over the years." By recruiting veterans who understand the "soul" of Halo but were perhaps constrained by previous management or technical hurdles, Activision could jumpstart its new team with a wealth of institutional knowledge.

Technological Independence and Release Strategy
O’Connor’s final piece of advice serves as a critique of past mistakes: the next Halo should not be tied to hardware launch cycles or forced to support aging platforms.
Halo Infinite was famously hamstrung by the requirement to run on the 2013 Xbox One hardware, which many analysts believe limited the scope of its open-world design and graphical fidelity. Furthermore, the pressure to launch alongside the Xbox Series X/S resulted in a rushed initial showing in 2020 that necessitated a year-long delay.
O’Connor advocates for a "software-first" approach. By developing specifically for modern PC hardware and current-gen consoles (and potentially the next generation), the developers can utilize the full power of Unreal Engine 5. This includes advanced features like Lumen for dynamic lighting and Nanite for high-detail geometry, which could finally deliver the "next-gen" Halo experience fans have been waiting for since the early 2000s.
Market Context and Competitive Analysis
The pressure on Activision to succeed with Halo is immense. The first-person shooter market is currently dominated by titles like Apex Legends, Valorant, and Activision’s own Call of Duty: Warzone. Meanwhile, Bungie’s Destiny 2 continues to capture the "sci-fi shooter" demographic that Halo once owned.
Data from SteamDB and Xbox engagement charts showed that while Halo Infinite peaked at over 250,000 concurrent players on Steam at launch, that number dwindled to below 10,000 within a year due to a lack of meaningful updates. In contrast, Call of Duty maintains a consistent ecosystem of millions of active users across its various platforms. By applying Activision’s "engagement-first" philosophy to Halo, Microsoft hopes to return the series to its status as a Top 5 most-played game globally.

Implications for the Future
The involvement of Activision marks the beginning of a "multi-studio" era for Halo. Much like how Call of Duty is rotated between Infinity Ward, Treyarch, and Sledgehammer Games, Halo may now benefit from a similar collaborative structure. This could allow for more frequent releases, such as a "Classic" multiplayer experience running alongside a narrative-heavy RPG or a tactical spin-off.
The ultimate success of this transition will depend on whether Activision can balance the clinical efficiency of its business models with the creative "magic" that O’Connor and his predecessors instilled in the series. If the new "purpose-built team" heeds O’Connor’s warnings regarding hardware limitations and talent retention, the next Halo could serve as the definitive comeback for the Master Chief. If not, the franchise risks becoming another entry in the long list of legacy IPs that struggled to find their footing in the modern era of gaming.
