Halo: Campaign Evolved, the ground-up remake of the 2001 shooter that built the Xbox brand, launches July 28, 2026, across Xbox Series X|S, PC, and PlayStation 5 simultaneously — the first time a mainline Halo title has appeared on a PlayStation console. Early access begins July 23 for buyers of the Premium Edition ($69.99) and Collector's Edition ($199.99); the Standard Edition carries a $49.99 price tag, and the game arrives day one on Xbox Game Pass Ultimate and PC Game Pass at no additional cost.
The confirmation came June 7 at the Xbox Games Showcase, where Halo Studios also revealed the name and plot of the three new prequel missions and disclosed key technical details, including a demanding PC requirement of an RTX 4080 graphics card and 32 gigabytes of RAM for 4K Ultra settings.
Operation: METEORITE Sends Master Chief Behind Enemy Lines
The headline addition beyond the rebuilt 10-mission original campaign is Operation: METEORITE, a three-mission story arc set one year before the events of Halo: Combat Evolved. The missions follow Master Chief and Sergeant Johnson on a clandestine UNSC infiltration operation aboard a Covenant research vessel — what Xbox describes as "a simple smash and grab" that escalates into something more complicated when the pair encounters "more than they bargained for."
The prequel content is included with every edition of the game and represents the franchise's most substantial canon expansion in years, predating the ring arrival and Flood discovery that define the original game's story. The missions were developed in collaboration with sci-fi novelist Troy Denning, whose work has shaped the Halo expanded universe across multiple acclaimed novels; a companion digital short story by Denning, "Halo: Hungry Buzzards," is included with the Premium Edition and leads into the events of Operation: METEORITE.
Halo Studios also confirmed that the new missions include space combat environments not present in the 2001 original, developed using Unreal Engine 5's Control Rig procedural animation system to support action sequences the original geometry and engine could not have handled.
Hybrid Blam and Unreal Engine 5: What the Rebuild Actually Required
The most technically significant aspect of Halo: Campaign Evolved is not its upgrade to Unreal Engine 5 — it is what the studio chose to preserve from the original engine alongside it. Under the hood, Halo Studios retained core code and simulation systems from Bungie's original Blam engine, specifically the Halo: Reach fork, to power the game's physics simulation, enemy AI behavior, and combat feel. Unreal Engine 5's Nanite virtualized geometry system and Lumen global illumination engine handle the visual rendering layer on top.
Nanite renders geometry at per-pixel triangle resolution, eliminating the polygon budget constraints and level-of-detail pop-in that defined the original game's 2001 hardware targets. Lumen replaces pre-baked static lightmaps with real-time multi-bounce dynamic global illumination — light sources respond dynamically to the environment rather than being fixed at creation time. Halo: Campaign Evolved is also the first game in the franchise to feature ray tracing in its campaign mode; Halo Infinite added ray tracing only to its multiplayer in a post-launch update.
The dual-engine approach is not accidental. Game director Greg Hermann noted that relying on Epic's technical support framework freed the team to focus entirely on gameplay and content — a direct contrast to Halo Infinite's development, during which the Slipspace Engine required simultaneous engineering investment alongside game design work. The decision mirrors the approach Bethesda and developer Virtuos used for The Elder Scrolls IV: Oblivion Remastered (2025), where original engine code was preserved alongside Unreal Engine 5 rendering to maintain gameplay behavior accumulated over the original's release. Both studios reached the same engineering conclusion: a game's "feel" is encoded in simulation-layer code that modern engines cannot faithfully reproduce by reconstruction alone.
The tradeoff surfaces clearly in the PC system requirements. Nanite's per-pixel geometry streaming and Lumen's real-time global illumination demand significantly more compute than the Slipspace engine's baked lighting approach. The minimum configuration to run the game at 1080p and 60 frames per second requires an RTX 2060 Super or AMD Radeon RX 6600 and 16 gigabytes of RAM; the Ultra preset at 4K and 60 frames per second requires an RTX 4080, 32 gigabytes of RAM, and 16 gigabytes of VRAM. An SSD with 100 gigabytes of available space is mandatory at every tier — a direct consequence of Nanite's real-time geometry streaming, which requires fast storage to feed assets without hitching.
First Halo on PlayStation in the Franchise's 25-Year History
Halo: Campaign Evolved launches simultaneously on PlayStation 5 — the first mainline Halo title ever released on a Sony platform. The franchise originated as an Xbox exclusive in November 2001 and remained one for 25 years. Pre-orders are available through both the Xbox Store and PlayStation Store.
The release arrives against a backdrop of deliberate platform bifurcation within Xbox's own lineup. At the same June 7 showcase, new Xbox CEO Asha Sharma confirmed that Gears of War: E-Day would launch October 6 as an Xbox and PC exclusive — a last-minute decision that reversed plans to bring the game to PlayStation 5, according to insider reporting from Jeff Grubb ahead of the showcase. The pairing makes the contrast explicit: Halo travels to PlayStation; Gears stays home. Xbox's platform strategy is not uniformly multiplatform — it is franchise-by-franchise, and the criteria for each decision have not been publicly specified.
A new trailer for Halo: Campaign Evolved released June 8 was captured on PlayStation 5 Pro hardware — a visual that would have been inconceivable for the franchise five years ago.
Halo: Combat Evolved Anniversary vs. Halo: Campaign Evolved
This is the third time Microsoft has revisited the 2001 original, but the first time it has done so as a full remake rather than a remaster. Halo: Combat Evolved Anniversary (2011) layered updated graphical assets over the original game's unchanged code, preserving original geometry beneath a switchable visual overlay. Halo: The Master Chief Collection (2014) bundled that 2011 version with subsequent entries but did not rebuild the underlying game.
Halo: Campaign Evolved is distinct on three counts: it replaces original assets with entirely new geometry and lighting; it adds three new canonical missions that were never in any prior release; and it introduces gameplay mechanics from later Halo titles — sprinting, vehicle hijacking, and nine additional weapons from across the franchise — while allowing players to toggle sprint off for a more classic experience.
What Does Halo: Campaign Evolved Cost, and Is It on Game Pass?
Halo: Campaign Evolved launches at $49.99 for the Standard Edition. The $69.99 Premium Edition includes the Alpha Halo Armory Pack, a digital artbook, the "Hungry Buzzards" digital short story, and the digital game manual, and grants five days of early access beginning July 23. The $199.99 Collector's Edition includes a 12-inch Dark Horse Master Chief statue, a light-up Cortana chip, a Steelbook case, three concept art prints, a physical game manual, and a game disc for Xbox Series X and PS5, in addition to five days of early access.
The game launches day one on Xbox Game Pass Ultimate and PC Game Pass — subscribers pay nothing beyond their existing membership.
All editions include Operation: METEORITE at no additional charge. The Foundry Armory Pack pre-order bonus requires orders placed by July 27, 2026 at 11:59 p.m. local time.
Studio Turbulence Behind the July 28 Launch
The development path to July 28 was not without turbulence. Halo Studios — which rebranded from 343 Industries in October 2024 as part of a strategic pivot away from the Slipspace Engine — had previously been hit by significant layoffs in January 2023 that affected more than 130 employees, primarily on campaign and narrative teams. A second wave of Microsoft layoffs in January 2024 impacted the studio again.
In April 2026, former art director Glenn Israel published detailed allegations on LinkedIn claiming harassment, fraud, and mismanagement at the studio between January 2024 and July 2025, naming specific senior representatives and accusing Microsoft's HR division of failing to investigate. Israel said his art team was reassigned from Halo: Campaign Evolved in August 2025 due to what he described as "catastrophic mismanagement" of the project, and that his own role was subsequently declared redundant. Microsoft had not issued a public response as of this article's publication. The allegations are specific, documented, and directly concern this game's production.
Frequently Asked Questions
Is Halo: Campaign Evolved the same as Halo: Combat Evolved?
Halo: Campaign Evolved is a ground-up remake of Halo: Combat Evolved's campaign, not a remaster. It rebuilds all original geometry, lighting, cinematics, and audio using Unreal Engine 5, adds three new canonical prequel missions (Operation: METEORITE), and introduces gameplay mechanics from later Halo games. It does not include competitive multiplayer.
What is Operation: METEORITE in Halo: Campaign Evolved?
Operation: METEORITE is a three-mission prequel story arc set one year before the events of Halo: Combat Evolved. It follows Master Chief and Sergeant Johnson on a UNSC covert operation aboard a Covenant research vessel, featuring new environments, enemies, and space combat sequences. It was developed with novelist Troy Denning and is included with every edition of the game at no extra charge.
Is Halo: Campaign Evolved on Game Pass?
Yes. Halo: Campaign Evolved launches day one on Xbox Game Pass Ultimate and PC Game Pass on July 28, 2026. Active subscribers can play the full game at no additional cost. The Standard Edition costs $49.99 for those who prefer to purchase outright.
Why does Halo: Campaign Evolved use two engines instead of one?
Halo Studios preserved core code from Bungie's original Blam engine — specifically the Halo: Reach version — to maintain the physics simulation, enemy AI, and combat behavior that define the franchise's feel, while using Unreal Engine 5's Nanite geometry and Lumen lighting systems for all visual rendering. The studio determined that reconstructing these simulation systems in a modern engine could not faithfully replicate the original game's behavior — the same conclusion Bethesda and Virtuos reached when rebuilding Oblivion Remastered in 2025.
