Following the anticipated arrival of Call of Duty: Modern Warfare (2019) to Xbox Game Pass later this week, new evidence suggests that Call of Duty: Vanguard, the 2021 installment in the long-running first-person shooter series, is also being prepared for inclusion in Microsoft’s popular subscription service. This development signals a clear acceleration in the integration of Activision-Blizzard titles into the Game Pass ecosystem, a strategic move following Microsoft’s landmark acquisition of the publishing giant. The revelation stems from the observed addition of a dedicated "Xbox for PC" version of Vanguard to the Microsoft Store, a technical precursor often indicative of a game’s impending availability on Game Pass for PC subscribers.
Technical Precursor: The Xbox for PC Version
The key indicator sparking this speculation is the appearance of Call of Duty: Vanguard‘s "Xbox for PC" version within the Microsoft Store. Prior to this, Vanguard was available on Xbox consoles, but its PC counterpart was primarily distributed through Activision’s Battle.net launcher. The creation and listing of an Xbox for PC version suggest a backend effort to standardize the game’s distribution across Microsoft’s platforms, a necessary step for its seamless integration into Game Pass. This process typically involves adapting the game to Microsoft’s Universal Windows Platform (UWP) or ensuring compatibility with the Xbox app on PC, enabling features like cloud saves, cross-platform play (where applicable), and direct management through the Xbox ecosystem. For developers and publishers, preparing a title for Game Pass on PC often entails this specific versioning, streamlining the delivery mechanism for subscribers. Industry observers frequently monitor such changes in digital storefronts as reliable early warnings for Game Pass additions, especially for titles not previously aligned with Microsoft’s PC gaming infrastructure.
A Shifting Landscape: Call of Duty and Game Pass
The potential addition of Vanguard comes on the heels of Modern Warfare (2019) being confirmed for Game Pass, marking a significant departure from Activision’s historical strategy regarding its flagship franchise. For years, Call of Duty titles maintained a premium price point, with new installments launching annually and older titles retaining their value through consistent sales. The integration into a subscription service represents a fundamental shift, directly attributable to Microsoft’s acquisition of Activision Blizzard, finalized in October 2023.
Microsoft’s intent behind the colossal $69 billion acquisition was multifaceted, but a primary driver was the enrichment of Xbox Game Pass with a vast catalog of popular titles, most notably Call of Duty. This strategy aims to bolster Game Pass subscriber numbers, enhance its value proposition against competitors, and solidify Xbox’s position in the evolving gaming landscape. The inclusion of Call of Duty is particularly impactful, given its immense global player base and consistent chart-topping sales. Prior to the acquisition, the idea of a Call of Duty title launching or even joining Game Pass was largely dismissed, highlighting the transformative power of the merger.

Call of Duty: Vanguard – A Brief Retrospective
Call of Duty: Vanguard, developed by Sledgehammer Games, launched globally on November 5, 2021. The game returned the series to a World War II setting, a thematic choice last explored by Sledgehammer Games with Call of Duty: WWII in 2017. Vanguard‘s narrative campaign followed a multinational squad of elite soldiers fighting on various fronts of the war, including Eastern and Western Europe, North Africa, and the Pacific. Its multiplayer component featured a diverse set of maps and modes, alongside the popular Zombies co-operative experience developed by Treyarch.
Upon its release, Vanguard received mixed to positive reviews. Critics generally praised its gunplay and the visual fidelity of its engine, but opinions were divided on the campaign’s execution and some of the multiplayer’s innovations. Commercially, Vanguard performed strongly, though it reportedly did not meet Activision’s internal sales expectations compared to previous installments like Modern Warfare (2019) or Black Ops Cold War. Despite this, it remained a significant seller and maintained a dedicated player base, particularly through its integration with the free-to-play battle royale title Warzone. The game’s historical setting and its place within the broader Call of Duty meta-narrative make it a distinct entry, offering a different flavor compared to the more contemporary or futuristic settings often explored by other titles in the franchise.
Chronology of Game Pass Integration and Future Outlook
The timeline for Call of Duty integration into Game Pass is becoming clearer, albeit with some anticipated delays.
- October 2023: Microsoft completes the acquisition of Activision Blizzard, signaling the inevitable arrival of their catalog on Game Pass.
- Early 2024: Xbox leadership confirms that Call of Duty titles would begin arriving on Game Pass, but not immediately "day one" for new releases.
- Late Spring 2024: Call of Duty: Modern Warfare (2019) is officially confirmed for Game Pass, slated for release later this week. This marks the first mainline Call of Duty title from the Activision Blizzard catalog to join the service.
- Coinciding with Modern Warfare (2019) announcement: The "Xbox for PC" version of Call of Duty: Vanguard is spotted on the Microsoft Store.
While the appearance of Vanguard‘s PC version is a strong indicator, it does not guarantee an imminent release. Industry precedent suggests that such backend preparations can sometimes precede a Game Pass launch by several months. Microsoft and Activision-Blizzard are likely managing a staggered release strategy for these high-profile titles to maintain consistent subscriber engagement and maximize the impact of each addition.
Furthermore, the Call of Duty franchise operates on a roughly three-year development cycle for its main studios. Sledgehammer Games, having released Vanguard in 2021, is widely expected to be the lead developer for the Call of Duty title slated for release in 2027, assuming the current development cycle holds. It is a plausible strategy for Microsoft to release Vanguard onto Game Pass in late 2026 or early 2027. This timing could serve as a strategic marketing tool, reigniting interest in Sledgehammer Games’ past work and building anticipation for their upcoming Call of Duty project, effectively leveraging the back catalog to promote future releases. This approach would align with how publishers often use older titles to generate hype for new ones within a franchise.

Strategic Implications for Microsoft and Game Pass
The gradual, yet steady, integration of Call of Duty titles into Game Pass holds significant strategic implications for Microsoft:
- Subscriber Growth and Retention: Call of Duty‘s immense popularity is a powerful draw. Offering these titles on Game Pass can attract new subscribers who might not otherwise join, and significantly enhance the perceived value for existing ones, reducing churn. As of early 2024, Xbox Game Pass boasts over 34 million subscribers, a figure Microsoft aims to expand significantly. High-profile additions like Call of Duty are crucial to reaching ambitious growth targets.
- Competitive Advantage: Game Pass directly competes with other subscription services and the traditional retail model. Having Call of Duty exclusively available through a subscription on Xbox and PC strengthens Microsoft’s position against rivals like PlayStation Plus and other digital storefronts.
- PC Gaming Expansion: The specific creation of an "Xbox for PC" version for Vanguard underscores Microsoft’s commitment to expanding Game Pass for PC. The PC gaming market is vast, and bringing major franchises like Call of Duty directly into the Xbox app on PC helps consolidate Microsoft’s presence and ecosystem on the platform. This also promotes the use of the unified Xbox app experience on Windows.
- Monetization Strategy: While Game Pass offers titles for a flat monthly fee, Call of Duty games are heavily monetized through in-game purchases, battle passes, and cosmetic items. By increasing the player base through Game Pass, Activision Blizzard can potentially boost engagement with these microtransactions, creating a diversified revenue stream beyond initial game sales.
- Leveraging the Acquisition: This move demonstrates Microsoft’s ability to successfully integrate Activision Blizzard’s intellectual property into its broader gaming strategy. It validates the immense investment made in the acquisition and showcases how these flagship franchises will be utilized to drive ecosystem growth.
Broader Industry Impact and Player Reaction
The broader gaming industry is closely watching Microsoft’s strategy with Call of Duty. The shift towards subscription models is a dominant trend, and the inclusion of a behemoth like Call of Duty accelerates this evolution. It prompts other publishers to re-evaluate their own strategies, particularly concerning older catalog titles. While some fear it could devalue premium game purchases, others see it as an opportunity to reach wider audiences and sustain engagement over longer periods.
Player reaction to Call of Duty on Game Pass has been overwhelmingly positive. The prospect of accessing a substantial library of games, including premium titles, for a single monthly fee is highly appealing. For players who may have missed Vanguard at launch or prefer to experience it without a full upfront purchase, its addition to Game Pass would represent significant added value. It also allows new players to explore the franchise’s history, potentially fostering new fans ahead of future releases. Analysts predict a surge in Game Pass sign-ups and renewed interest in Vanguard‘s multiplayer and campaign modes upon its eventual release into the service.
In conclusion, the appearance of an "Xbox for PC" version for Call of Duty: Vanguard in the Microsoft Store is a compelling signal that another major Activision title is making its way to Xbox Game Pass. This development is a direct consequence of Microsoft’s strategic acquisition of Activision Blizzard, aiming to significantly bolster its subscription service. While the exact timing remains to be confirmed, the move underscores Microsoft’s commitment to integrating these valuable IPs, driving Game Pass growth, and reshaping the landscape of game distribution and consumption for the years to come. Players can anticipate a growing library of Call of Duty experiences becoming accessible through their Game Pass subscriptions, fundamentally altering how they engage with one of gaming’s most iconic franchises.
