Sister Other Paranoia Platforms

Confirmed storefront: Steam PC

Sister Other Paranoia launches as a Steam title (app 4240150). Development sits with HazeDenki; scenario and direction are by nyalra; worldwide publishing is by Serenity Forge. Public press—Automaton and similar launch coverage—names Windows and macOS for the Steam release window. This wiki treats those two desktop targets as the honest platform pitch and does not invent day-one console or mobile ports.

If you only need “where do I buy it,” the answer is the official Steam product page. If you need “will my machine run it,” split Windows store specs from macOS press naming and read System Requirements for the detailed table.

Windows: store-listed requirements

Steam publishes a Windows minimum and recommended block for Sister Other Paranoia. In short, plan for a 64-bit Windows 10 baseline, dual-core class CPU at minimum, DirectX 11 capable graphics (integrated GPUs included at the minimum tier), and a few gigabytes of free storage. Recommended rows lean toward stronger CPU/GPU and more RAM for comfort, overlays, and media playback.

Windows is the platform with the clearest public hardware checklist. That does not make macOS fake; it only means the Windows table is what most scrapes and storefront screenshots currently emphasize. Re-open Steam on launch week if patches change depot size.

macOS: reported by press, verify on Steam

Launch articles that announce the mid-August 2026 window commonly say Windows and macOS via Steam. That is meaningful: Mac is part of the reported ship set, not a random forum wish. At the same time, this wiki will not invent a full Apple silicon versus Intel matrix, macOS version floor, or Metal feature list that your Steam client has not shown.

Practical Mac checklist:

1. Open the Sister Other Paranoia Steam page while signed in on macOS.
2. Confirm the platform filter actually includes Mac for your account/region.
3. Look for any separate Mac requirements block after the page fully loads.
4. If a demo appears through official Discord messaging, use that demo as real compatibility proof.
5. Leave headroom for the Steam client itself, not only the game depot.

Until those checks pass on your machine, treat macOS as reported for Steam launch rather than as a wiki-invented benchmark chart.

Steam Deck: unknown until verified

Steam Deck verification badges arrive on Valve’s schedule. Before a deck verification label appears on the store, this wiki will not claim Perfect, Playable, or Unsupported as fact. A classic 2D visual novel often runs acceptably on handheld PCs, but “often” is not a verification badge.

If you plan to play on Deck at launch:

• Check the Steam page for a Deck verification row near unlock.
• Test community controller templates only after install—do not assume a custom official layout exists day one.
• Remember text readability and trackpad/click comfort matter as much as raw performance for a VN.

We will update platform notes when Steam itself publishes a verification state. Until then, Deck remains unknown.

What is not part of the confirmed package

Based on public materials used for this wiki, the launch package described here does not include:

• Nintendo Switch, PlayStation, or Xbox day-one releases
• A mobile App Store / Google Play build
• A non-Steam exclusive launcher requirement

If Serenity Forge or HazeDenki later announce ports, those announcements—not speculation threads—should update your expectations. Wishlist and buy on Steam for the PC versions that are actually named.

Launch timing and buying path by platform

Platform choice does not change the worldwide unlock moment. Steam calendars often show August 14, 2026. Reported official timing is August 14, 8:00 PM PT / 11:00 PM ET, matching August 15, 3:00 AM UTC and August 15, 12:00 PM JST. Convert your city on Launch Times; read planned-date caveats on Release Date.

Price coverage sits around $9.99 USD before regional tax. Wishlist from the correct Steam account on Wishlist, then follow How to Buy so you do not install on the wrong profile. First-session habits after download live on Getting Started.

Languages on those platforms

Steam lists English, Japanese, and Simplified Chinese for interface and subtitles on the PC Steam build. This wiki covers English and Japanese articles only; see Languages for that distinction. Language availability is a store feature of the Steam release, not a promise that every future port will ship the same set on day one.

Demo, Discord, and streaming on PC

A free demo has been pointed at through the HazeDenki Discord community (“Don’t tuch grass” / Don’t touch grass). Demo builds are the best platform proof before you spend money—especially on macOS or handheld PCs. Bug reports belong on that Discord.

Steam’s page text allows streaming and uploads, including spoilers, and monetization without prior permission. That policy is about creator rights on Steam’s PC build; it does not invent console capture rules for platforms that are not launching.

Honest limits

We will not invent Steam Deck ratings, fake console skus, or macOS model blacklists. Windows requirements come from the store table; macOS comes from press naming plus your live Steam check; Deck stays unknown until Valve’s badge appears. Sister Other Paranoia is a Steam PC visual novel first—plan for Windows or macOS, clear system requirements, and spend remaining attention on whether the story’s mature themes belong in your library.
