Forza Horizon 6 Suffers Disastrous 155GB Steam Leak: Unencrypted Preloads, 8000-Year HWID Bans, & Loyalty Rewards Explained

The Unprecedented Forza Horizon 6 Unencrypted Steam Preload Leak

The launch of Forza Horizon 6 was supposed to be a seamless victory lap for Microsoft and Playground Games. Setting the festival in the highly demanded streets of Japan—specifically kicking off in Tokyo City—the hype was palpable. But over the weekend, the racing giant suffered what can only be described as a catastrophic digital infrastructure failure.

A monumental 155 gigabytes of Forza Horizon 6 game files were pushed to SteamDB. The core issue? They were completely unencrypted.

As a resident analyst here, I’ve tracked massive industry leaks before, but the Forza Horizon 6 steam unencrypted preload leak stands in a league of its own. IGN reports that this massive cache of files arrived four days ahead of the May 15 early access period and a full nine days before the May 19 general release date.

Under standard operational procedure, Steam preloads are heavily encrypted. Valve’s backend allows developers to distribute large files to players’ hard drives early using AES-256 encryption. The decryption key is only pushed to the Steam client at the exact moment the publisher authorizes the global launch.

In this instance, it appears a critical human error occurred at the publishing level. Whoever managed the Steamworks backend for Xbox Game Studios seemingly uploaded the build to the public-facing branch without the encryption flag checked, or mistakenly triggered the decryption update prematurely.

The result was immediate. The unencrypted 155GB payload was ripped, repackaged, and seeded across piracy networks within hours.

Deeper Technical Analysis: The DRM Failure

From a technical standpoint, the absence of Denuvo or any secondary third-party DRM (Digital Rights Management) on the Steam version made this leak profoundly damaging. Microsoft relies heavily on the Xbox app ecosystem and the Microsoft Store’s UWP (Universal Windows Platform) containerization to protect its games.

However, releasing on Steam means stripping away some of those UWP protections to interface with Steam’s API. Because the Steamworks DRM was bypassed by an accidental unencrypted push, pirates essentially gained access to a DRM-free, retail-ready build.

This presents a fascinating data point for the industry. Despite this massive leak, Forza Horizon 6 remains the second top-selling game by revenue on Steam right now. This strongly indicates that the core PC demographic is willing to pay for seamless multiplayer connectivity, cloud saves, and legitimate updates, rendering the piracy threat less impactful to bottom-line sales than historically assumed.

Microsoft’s Retaliation: The Forza Horizon 6 Motherboard HWID Ban

If you thought Microsoft would take this lying down, think again. According to reports from Wccftech, the community team is dropping the absolute heaviest hammer possible on early leakers and pirates.

Players caught booting up the leaked build are being met with a suspension notice for “cheating/unallowed modding.” The expiration date for this ban? December 31, 9999.

This is essentially an 8,000-year ban, but the real punishment lies in the methodology. Microsoft isn’t just banning Xbox Live gamertags; they are executing a Forza Horizon 6 motherboard HWID ban.

A Hardware ID (HWID) ban is a severe level of moderation. It means the telemetry services within the game have hashed the serial numbers of the user’s motherboard, CPU, and potentially their MAC address, flagging that specific combination of hardware on Microsoft’s servers.

A simple Windows reinstall will do nothing. Creating a new Xbox account will do nothing.

To bypass this, cheaters and pirates are forced to rely on third-party “HWID spoofers,” which operate at the kernel level to feed false hardware serials to the game. However, as noted in community discussions, these spoofers are notoriously dangerous, often bundled with malware, crypto-miners, or keyloggers.

The contrasting viewpoint here is whether an HWID ban is an overreach for playing a game early. While piracy is illegal, some users who unknowingly downloaded the leaked files might find their expensive gaming rigs permanently blacklisted from Microsoft’s flagship racing title. Ultimately, the only 100% safe way to recover from an HWID ban is to physically purchase and install a brand-new motherboard.

How to Play Forza Horizon 6 Early Access in Japan (Legally)

For those who want to avoid a millennium-long hardware ban, there are legal pathways to play early. The early access period officially begins on May 15, four days ahead of the May 19 standard launch.

Pure Xbox confirms that players have two main routes. The first is buying the Forza Horizon 6 Premium Edition outright for £109.99 / $119.99. This behemoth of a package includes the base game, VIP Membership, a Welcome Pack, a Time Attack Car Pack, a Car Pass (delivering 30 cars, one per week), the Italian Passion Car Pack, and access to two future premium expansions.

But the real value injection lies in the Forza Horizon 6 premium upgrade Game Pass cost strategy. Since Forza Horizon 6 is a first-party Microsoft title, the standard edition launches day-one on Xbox Game Pass Ultimate and PC Game Pass.

If you are a Game Pass subscriber, you do not need to buy the $120 Premium Edition. Instead, you can purchase the Premium Upgrade Bundle for £59.99 / $59.99. This grants you the May 15 early access and all the DLC perks, layering onto your existing Game Pass license.

It’s an aggressive monetization strategy by Microsoft, effectively getting Game Pass subscribers to spend the equivalent of a full retail game price just for early access and DLC. Yet, considering the massive 155GB download size and the stunning new Japanese locale, millions are already pulling out their wallets.

The Forza Horizon 6 Loyalty Rewards Free Cars List

When you finally step into Tokyo City and complete the introductory race, returning players will be greeted with a generous garage injection. Traxion reports that Playground Games is returning to its tradition of rewarding franchise veterans.

Here is the complete Forza Horizon 6 loyalty rewards free cars list:

• Forza Motorsport (2023): 2024 Chevrolet Corvette E-Ray
• Forza Horizon 5: 2021 Mercedes-AMG ONE
• Forza Horizon 4: 2016 Aston Martin Vulcan
• Forza Horizon 3: 2016 Lamborghini Centenario LP 770-4
• Forza Horizon 2: 2014 Lamborghini Huracán LP-610-4
• Forza Horizon (2012): 2013 Dodge SRT Viper GTS

If your Xbox Gamertag is linked to saves from these previous titles, these cover cars unlock automatically.

Contrasting Viewpoints on Progression Balancing

While receiving six hypercars for free sounds incredible, it brings up a recurring critique of the Forza Horizon formula. By handing players a Mercedes-AMG ONE and an Aston Martin Vulcan within the first hour of gameplay, the sense of progression is completely shattered.

Historically, racing games required you to grind through low-tier hatchbacks before earning the right to pilot a V12 hypercar. Forza Horizon has long been criticized for its “wheelspin” economy, which throws million-dollar vehicles at the player like confetti.

Playground Games has claimed that Forza Horizon 6 will address this by gating faster car classes behind later “Wristband events” in the campaign. However, the immediate injection of these loyalty rewards seems to directly contradict that design philosophy.

If a player can just hop into a Lamborghini Centenario right after the tutorial, why would they ever bother tuning a C-Class Nissan Silvia for the early Tokyo street races? While the loyalty rewards are optional, the temptation is often too great, leaving the early-game economy feeling somewhat disjointed.

The Shift to Tokyo City

The setting itself is perhaps the most exciting data point. Moving from Mexico to Japan represents a massive tonal shift for the franchise. The dense, neon-lit streets of Tokyo offer a stark contrast to the wide-open deserts and jungles of previous entries.

This environment will likely mandate a shift in the physics engine, focusing more heavily on tight, technical cornering, drifting mechanics, and verticality on highway overpasses. The 155GB file size is a testament to the texture density required to render a major metropolitan area accurately.

Furthermore, we anticipate that the PC system requirements will be incredibly demanding, particularly for ray-traced global illumination in a city full of reflective puddles and neon signs.

Final Thoughts

The Forza Horizon 6 launch will be studied in gaming history books. On one hand, you have an unprecedented 155GB unencrypted Steam leak that resulted in catastrophic piracy. On the other, you have Microsoft executing draconian 8,000-year motherboard HWID bans, setting a terrifying precedent for future anti-piracy measures.

Despite the technical fumbles on the Steam backend, the hype for exploring Japan remains untouched. Whether you are paying $60 to upgrade your Game Pass copy for early access, or waiting until May 19th to claim your fleet of loyalty hypercars, the Horizon festival is back.

Just make sure you play it legally—unless you plan on buying a new motherboard before the year 9999.
