Halo Studios has published the PC system requirements for Halo: Campaign Evolved, the Unreal Engine 5 remake of the 2001 classic, and they carry a hard line: Windows 11, 16 GB of RAM, and 100 GB of storage are the new floor. Announced on July 17, 2026 — just over a week before early access begins on July 23 — the specs officially shut out Windows 10 machines and 8 GB PCs, signaling a shift toward next-gen hardware expectations for a campaign-focused release.

What’s Under the Hood: The Full PC Specs

The Steam listing, first reported by GamesHub, lays out two tiers. Minimum calls for an AMD Ryzen 5 3600 or Intel Core i7-10700K, paired with 16 GB of system memory and a GPU at least in the class of an AMD Radeon RX 6600, Intel Arc A580, or Nvidia GeForce RTX 2060 Super. Storage is listed as 100 GB on both tiers—a figure Halo Studios says may grow with patches and temporary install files. For the recommended experience, players will need a Ryzen 7 7700 or Core i7-12700K, 32 GB of RAM, and a Radeon RX 9070 or GeForce RTX 3080 Ti. There’s no mention of target resolutions, graphics presets, or frame rates; “minimum” just means the game will run, not that it’ll deliver a smooth 1080p60.

What This Means for Your Gaming Rig

For everyday Windows users, the most immediate takeaway is that Windows 10 is not supported. If you’re still running Microsoft’s older OS — which remains on hundreds of millions of PCs — you won’t even meet the baseline. With the game set to launch in late July 2026, Microsoft’s own support for Windows 10 isn’t far off: mainstream support ended in 2025, and annual extended security updates are available only to organizations. Gamers who haven’t yet made the jump to Windows 11 now have a hard deadline if they want to play one of the year’s biggest Xbox Game Studios titles on their own rig.

Beyond the OS, the minimum RAM requirement is double that of many mainstream laptops and older gaming desktops still rocking 8 GB. If your system has only 8 GB of DDR4, you’ll need to add another stick or consider a new build. The GPU threshold, while not monstrous, cuts off any card older than the RTX 2060 Super or RX 6600 series — cards like the GTX 1060 or RX 580, popular Steam survey staples, fall short. The 100 GB storage demand, meanwhile, is hefty even by modern standards. A campaign-only game without competitive multiplayer gobbling up maps and assets might raise eyebrows, but Halo Studios has rebuilt everything from the ground up in Unreal Engine 5, including 4K assets, remastered audio, and entirely new missions. Factor in the way modern engines duplicate data for faster load times on SSDs, and the 100 GB becomes plausible — though HDD users should expect sluggish performance; an NVMe SSD is effectively mandatory.

Home users should check their PC specs now: open Settings > System > About, or run dxdiag. Confirm you’re on Windows 11 (or be ready to upgrade), verify installed RAM, and check disk space. If you fall short, you might still play the game through Xbox Cloud Gaming (it’s a day-one Game Pass Ultimate title), which streams to lower-end PCs, phones, and tablets, bypassing local hardware requirements entirely. For IT professionals managing fleets, the Windows 11 mandate may accelerate hardware refresh cycles, especially in departments that allow personal-use gaming rigs. Developers and modding communities should note that the Unreal Engine 5 foundation may open doors for custom content down the line, though Halo Studios hasn’t commented on mod support.

The Context: Why the Specs Are So High

Halo: Campaign Evolved isn’t the first remaster — but it’s the first full remake. The 2011 Anniversary edition was a visual polish layered atop the original engine, and it ran on Windows 7 and early Windows 10 machines without issue. This time, Halo Studios (rebranded from 343 Industries) has rebuilt the entire campaign in Unreal Engine 5, adding new story missions (including a three-mission arc with Sgt. Johnson), weapons, vehicles, and a third-person camera option. The result is a truly modern title that leverages the latest graphics APIs and Windows 11-specific optimizations. Microsoft has been pushing Windows 11 as a gaming platform, touting features like DirectStorage, Auto HDR, and improved thread scheduling for hybrid CPU architectures. While the game’s Steam page doesn’t explicitly list DirectStorage as a requirement, it’s likely part of the underlying tech that makes Windows 10 infeasible.

This isn’t the first high-profile game to demand Windows 11. Titles like Starfield and Forza Motorsport arrived with the same requirement, though some were later unofficially run on Windows 10 through workarounds. Here, the move feels more definitive, perhaps because Halo Studios doesn’t want to support an OS with dwindling security patches. Simultaneously, the 16 GB RAM floor echoes a broader trend: recent AAA games such as Returnal, The Last of Us Part I, and Forspoken have all listed 16 GB as a minimum, reflecting the memory needs of large open worlds and high-quality assets. The 100 GB storage also aligns with Unreal Engine 5 titles like Black Myth: Wukong (130 GB) and STALKER 2 (150 GB). In other words, Halo: Campaign Evolved’s specs are aggressive but not outliers.

What You Should Do Right Now

If you’re a Halo fan planning to play on PC, take stock now. First, check your OS: if you’re still on Windows 10, you can upgrade to Windows 11 for free provided your hardware supports TPM 2.0 and meets the CPU requirements. Use Microsoft’s PC Health Check tool to verify compatibility. If your CPU is older than the minimum listed (e.g., a Ryzen 5 2600 or Core i5-9400), you’ll likely need a new processor—and possibly a new motherboard. For RAM, 16 GB kits of DDR4 are inexpensive, costing as little as $30; if you only have 8 GB, this is the cheapest fix. For storage, confirm you have at least 100 GB free on an SSD; if not, consider a 1 TB NVMe drive (prices have crashed to around $50) and clone your system over. If your GPU is below an RTX 2060 Super, RX 6600, or Arc A580, that’s the priciest component to replace. Current-gen equivalents like the RTX 4060 or RX 7600 XT will handle it easily, but used markets for RTX 3060 Ti or RX 6700 XT also offer value.

Alternatively, if your PC is far behind and you don’t want to invest, remember that Halo: Campaign Evolved launches day one on Game Pass Ultimate. With a subscription, you can stream the game via Xbox Cloud Gaming to a low-spec laptop, tablet, or even a smart TV with a controller. It’s also available natively on Xbox Series X|S and PlayStation 5. The digital Standard Edition is $49.99, Premium (with five days early access and cosmetic packs) is $69.99, and the Collector’s Edition with a statue is $199.99. Physical disc copies exist for Xbox and PS5, but PC is digital only (Steam code for Collector’s). Pre-ordering on Steam is possible now, but waiting for post-launch benchmark tests might be wise if your hardware is borderline.

Keep an eye on official channels for final specs. Halo Studios warns that the published requirements are pre-release and could change. It’s also worth noting that no performance targets are provided, so “recommended” might still mean 1080p30 with upscaling — we simply don’t know. Community testing after launch will reveal real-world performance on a range of GPUs.

What to Watch Next

Halo: Campaign Evolved is a bellwether for Microsoft’s commitment to leaving behind legacy hardware. With Windows 10’s end-of-life clock ticking and more Xbox first-party titles moving to Unreal Engine 5, the days of broad compatibility are numbered. For PC gamers, the message is clear: if you want to play the latest blockbusters, Windows 11 and at least 16 GB of RAM are the new baseline. As the release date approaches, updates on DLSS/FSR support, Steam Deck compatibility, and potential tweaks to storage requirements will be worth watching.
