How big is Hela: of Mice & Magic: download size on every platform

Last checked: October 25, 2026

No official download or install size for Hela: of Mice & Magic has been announced yet, so the number you need for your drive is not confirmed. The game is tracked for a 1 December 2026 release on PC (Windows), and this page will be updated as soon as Microids, Windup Games or the store listings publish final figures.

Hela: of Mice & Magic file size by platform

Here is everything currently known, platform by platform. A row marked “not confirmed” means that no figure has come from the publisher, the developer or a live store listing. It does not mean the version is cancelled or the size is small.

PC is the only platform this page tracks with a launch date. Treat any console size you see quoted elsewhere as unverified until it shows up on an official store page or in a publisher post.

What has been confirmed about Hela: of Mice & Magic

The facts that matter for planning storage are thin right now, so it helps to separate what is solid from what is still placeholder.

Confirmed or reliably reported:

• The game is developed by Windup Games, an independent studio based in Umeå, Sweden.
• Microids, the French publisher, is handling publishing.
• You play as a small mouse helping a witch named Hela, solving physics and environmental puzzles across a hand-built world.
• It supports solo play and online co-op, which the official marketing positions as a wholesome adventure for small groups of players.
• The date tracked for this page is 1 December 2026 on PC (Windows).

Not confirmed or not announced yet:

• Download size on any platform.
• Installed size on any platform.
• Free space required for patching.
• Preload availability, start date or preload size.
• Day-one patch size.
• Console release dates and console file sizes.

If you have seen a precise gigabyte figure on a database site or forum, check where it came from. Unless it traces back to Steam, the PlayStation Store, the Microsoft Store, the Nintendo eShop or an official Microids or Windup Games channel, it is a guess.

Download size vs install size vs free space

These three numbers get mixed up constantly, and they are rarely the same. Knowing the difference will save you from deleting games you did not need to delete.

Download size

This is the amount of data your platform pulls from the store’s servers. Steam, Xbox and PlayStation all compress game files for delivery, so the download is usually smaller than what ends up on your drive. On a metered or capped connection, this is the number that counts against your data allowance.

Install size

Once the download is unpacked, the game takes up its installed size. This is what you will see in your Steam library under Properties, or in the storage menu on a console. It is the figure that tells you how much of your SSD the game will occupy long term.

Free space needed

Platforms need working room on top of the install. Steam, for example, stages patches by writing new files before removing old ones, so a game can temporarily need noticeably more space than its final installed size. Consoles do something similar during updates. When a store page lists “storage required,” it usually refers to this free space figure rather than the final footprint.

For Hela: of Mice & Magic, none of these three numbers has been published as a final figure.

How to check the size yourself once it goes live

Store listings update before the publisher announces anything, so checking them directly is the fastest route to a real number. The method differs slightly by storefront.

On Steam, the download queue also shows the compressed download size the moment a preload or purchase begins. That is the most accurate pre-launch figure you can get, because it reflects the actual build being delivered.

If console versions are confirmed, the PlayStation Store and Microsoft Store tend to show a size near the bottom of the product page once a preorder or preload is live. The Nintendo eShop lists required space on its product pages too. Until those pages exist for this game, there is nothing to check.

Preload: what to expect

No preload has been announced for Hela: of Mice & Magic. Microids has not said whether PC players will be able to download early, how many days before launch it would open or what the preload size would be.

Here is how preloads generally work across the stores, so you know what to look for when an announcement lands:

Smaller publishers do not always enable preloads on PC, especially for games that are not expected to be large. If no preload appears, you will simply download on launch day.

What will drive the file size

Without an official number, the honest answer is that nobody outside the studio knows the final size. What you can do is understand which parts of a game like this take up space, so the eventual figure makes sense.

Art style and world scale

Hela is a 3D game built around a tiny protagonist in a world scaled to a mouse. That design leans on detailed environments, close-up textures and objects the mouse climbs over, pushes and interacts with. High-resolution textures are usually the single biggest contributor to a game’s install size, so the level of texture detail Windup Games ships will matter more than the length of the campaign.

Physics-based puzzles and items

The puzzle design centres on manipulating objects in the environment. Physics data and object meshes take far less room than textures or audio, so the number of puzzles and items will have a modest effect on the total.

Audio and voice

Music, ambient sound and any voiced dialogue add up quickly, especially when a game ships multiple languages. Microids publishes across Europe and beyond, so localisation is likely to be broad. Whether languages ship as separate optional packs or in the base download has not been confirmed.

Co-op and online features

Online co-op itself adds little to the file size. The code for networking and matchmaking is small compared with art and audio. If co-op requires every player to own and install the game, each player will need the full install. Whether a friend’s pass or similar sharing option exists has not been announced.

Platform differences

When games launch on several systems, sizes differ because each platform compresses assets differently and some versions ship lower-resolution textures. A Switch version, if one is confirmed, would almost certainly be packaged differently from the PC build. That is why this page shows a separate row for each platform instead of assuming one number covers all of them.

Hela: of Mice & Magic system requirements

Storage is only one line of the PC requirements. Final minimum and recommended specs have not been confirmed by Microids or Windup Games, and any requirements block shown before launch should be treated as provisional.

When final specs arrive, the storage line and whether an SSD is required are the two details to watch. Many recent 3D games list an SSD as required or strongly recommended because they stream assets during play, and a hard drive can cause stutter or long loads even when the game technically installs.

About the game

For readers who landed here looking for more than a storage figure, here is a short factual overview of what Hela: of Mice & Magic is.

The premise

You play as a mouse working on behalf of Hela, a witch. The adventure plays out across a world built at mouse scale, where everyday objects become obstacles, platforms and puzzle pieces. The focus is on exploration and problem-solving rather than combat.

Gameplay

The core loop mixes platforming with physics-driven puzzles. You move, climb and use magic to interact with the environment, and puzzles often depend on moving or combining objects in the world. Some of the official material shows the mouse carrying a small backpack, which ties into how items are gathered and used.

Solo and co-op

The game is designed to be played alone or with friends in online co-op. The official messaging frames it as a cooperative, family-friendly experience. Exact player counts for co-op, local split-screen support and crossplay between platforms have not been confirmed for the PC launch, so check back for a dedicated update once those details are official.

Visual style

Windup Games has shown a soft, storybook-like look with warm lighting and handcrafted environments. That kind of visual style is the reason texture work, rather than raw content length, will likely be the main factor in the final file size.

The studio and publisher

Windup Games is a Swedish independent studio based in Umeå, in northern Sweden, and Hela is its debut project. Microids is a long-running French publisher known for adaptations and adventure titles, with a catalogue that includes the Asterix and Garfield series of licensed games and various narrative adventures. Microids is part of the Media-Participations group.

How Hela compares with other upcoming games

Since no number exists yet, a comparison has to be about category rather than gigabytes. A puzzle-adventure with a stylised art direction will almost certainly sit far below open-world blockbusters. The GTA 6 file size, for instance, is expected to be on an entirely different scale, and the same goes for how many GB Battlefield 6 needs on each platform, given its multiplayer maps and high-fidelity assets.

Hela belongs to a different tier: games with a defined set of hand-built areas rather than a sprawling world. If you are tracking several cosy or indie launches at once, the Emberville file size and the DREADMOOR file size are useful reference points for planning storage around similar-sized releases, and each of those pages notes what has and has not been confirmed.

If your main concern is a PC that is already tight on space, it is worth checking how much your existing games take up. Live-service titles grow with every season, and Fortnite PC storage requirements are a good example of how a single game can quietly consume a large share of a drive.

Planning your storage before 1 December 2026

You do not need the final number to get ready. A few simple steps will make launch day painless.

1. Clear some buffer space. Because the final size is unknown, keep a comfortable margin free on the drive you plan to install to. Patches need temporary space on top of the install.
2. Install to an SSD if you have one. Final requirements are not confirmed, but SSDs reduce load times in modern 3D games and are increasingly required.
3. Check your Steam library folders. Steam lets you add multiple library folders across drives. If your main SSD is full, you can set up a second library on another drive and choose it during install.
4. Watch for a preload announcement. If Microids enables a preload, you can spread the download over a few days instead of competing with every other player at launch.
5. Remember co-op partners. If you plan to play with friends, each of you will need your own install unless a sharing option is announced.

Why there is no number yet

It is normal for a game this far from launch to have no published file size. Studios typically lock their final build only weeks before release, and compression, texture packing and localisation choices all change the total until that point.

Store pages often go live months in advance with placeholder system requirements. Those placeholders are sometimes rounded generously so the final build fits under them. That is why this page reports “not confirmed” rather than copying a pre-launch storage line as if it were the final download size.

Expect the following sequence as launch approaches:

This page will be refreshed at each stage, with the date of every change recorded in the Quick answer box at the top.

Updates to this page

Each time official information is published, the table and Quick answer box will be updated with:

• The confirmed download size per platform, in GB.
• The installed size after unpacking.
• The free space required to install and patch.
• Preload dates and preload size, if a preload is offered.
• Day-one patch size, once known.
• Any change to the 1 December 2026 PC date.

Sizes change after launch too. Patches, new content and language packs can push the install up, and occasional optimisation updates bring it down. Every figure on this page will be stated with the date it applies to.

FAQ

How many GB is Hela: of Mice & Magic?

The final size has not been confirmed. Steam’s official store page lists a storage requirement of 15 GB available space for both minimum and recommended specs, but the final download and install sizes may differ.

When does Hela: of Mice & Magic release?

The date tracked for this page is 1 December 2026 on PC (Windows). Console release dates have not been confirmed.

Can you preload Hela: of Mice & Magic?

No preload has been announced. If Microids enables one on Steam or other stores, the start date and preload size will be added here.

Is Hela: of Mice & Magic coming to PS5, Xbox or Switch?

Console versions and their release dates are not confirmed for the date this page tracks. Each console row in the table above will be filled in once official store listings or publisher announcements confirm them.

Do I need an SSD to play Hela: of Mice & Magic?

Final system requirements have not been confirmed, so an SSD requirement is not confirmed either. An SSD is a safe choice for any modern 3D game because it shortens load times.

Does co-op need a separate download?

Co-op is part of the game, not a separate download. Whether every co-op partner needs to own and install their own copy has not been officially detailed, so assume each player needs the full install until told otherwise.

Who makes Hela: of Mice & Magic?

Windup Games, an independent studio in Umeå, Sweden, develops the game. Microids publishes it.

Official spec sheets are the starting point, but Sam treats them as claims to be checked rather than settled facts, so a published 50 GB install gets compared against what the launcher reports after day-one updates. He also looks past the headline numbers. A recommended GPU means little without knowing which resolution, frame rate and settings preset the developer had in mind, so those details go in the entry whenever the publisher states them. Unconfirmed figures are flagged as such.
