Halloween: The Game system requirements
Both tiers below are the values Steam publishes for app 3219630, reproduced without rounding or interpretation. Two of them are stricter than people expect and are worth reading before you buy: the OS floor is Windows 11 rather than Windows 10, and an SSD or NVMe drive is listed as required, not recommended.
| Minimum | Recommended | |
|---|---|---|
| OS | Windows 11 64-bit | Windows 11 64-bit |
| Processor | Intel LGA 1200+ / AMD AM4+ (Zen 2+) | Intel LGA 1700+ / AMD AM5+ |
| Memory | 16 GB | 32 GB |
| Graphics | GTX 1660+ / RX 590+ / Arc A770+ (1080p@30fps) | RTX 3000 series / RX 7000 series (4k@30fps) |
| DirectX | Version 12 | Version 12 |
| Storage | 45 GB available space, SSD/NVMe required | 45 GB available space, SSD/NVMe required |
| Network | Broadband internet connection | Broadband internet connection |
A 64-bit processor and operating system are required at both tiers. The minimum graphics line is quoted for 1080p at 30fps and the recommended line for 4K at 30fps — the store listing attaches those targets to the GPUs itself, which is more specific than most listings and worth taking literally.
Steam Deck
Not rated. Valve’s Deck compatibility endpoint returns Unknown for this app, which means it has not been through the review that assigns Verified, Playable or Unsupported. That is a genuine absence of information rather than a negative result.
What can be said from the specs alone: a GTX 1660-class GPU as the 1080p30 minimum is above the Deck’s comfortable range, and the listing’s Windows 11 floor says nothing useful about SteamOS either way. Anyone reporting it as Verified is reporting something Valve has not published.
Frequently asked
- How much space does Halloween: The Game need?
- 45 GB of available space, and the store listing states an SSD or NVMe drive is required rather than recommended. That requirement sits on both the minimum and the recommended tier, so a mechanical hard drive is not a supported configuration at any spec level.
- Can it run on Windows 10?
- The store listing states Windows 11 64-bit on both the minimum and recommended tiers. Windows 10 is not listed. That is a stricter OS floor than most releases and it is worth checking before buying, especially since a large share of the search traffic around this game is people asking exactly this.
- Does it work on Steam Deck?
- Unrated. Valve's Deck compatibility report for the game currently returns Unknown, meaning it has not been through the Verified or Playable review. Between that, the Windows 11 requirement and a GTX 1660-class minimum GPU, treat Deck as untested rather than as a yes or a no.
- Is there a macOS or Linux version?
- No. Steam's platform field for the game lists Windows only, with macOS and Linux both false.
- Do I need to be online to play?
- The store listing requires a broadband internet connection at both spec tiers, which is expected for the 1v4 multiplayer. What that means for the single-player story mode is not spelled out in any official source, and it is a question players have raised.
