Alien Invasyndrome Updates Hub

What this hub covers

Alien Invasyndrome is still a TBA full release with a playable Steam Demo on app 4603980 (Demo package 4830300, Steam store date 24 July 2026). This Updates Hub tracks how to think about Demo versioning — from early 0.65 footage through late 0.99.x into a Demo 1.0 hotfix (May 2026) content checkpoint still current as of 21 August 2026 — plus Steam wishlist status, language support (EN / JP), Windows-only platforms, and adult-only store flags without pretending patch notes are frozen forever.

Developer Mozu Field / 百舌鳥, publisher Shady Corner Games. Adult 18+ framing applies; pages stay mechanical and brief about adult content.

Pages in this section

1. Changelog — Demo 1.0 hotfix framing, change classes, softlock / detection re-tests, and how to verify your installed version.
2. Demo Scope — what the Demo includes vs TBA full game, save friction, wishlist expectations.
3. Demo Access — official Steam wishlist + Demo install framing (no piracy mirrors); support paths.
4. Platforms & APK — Windows-only Steam Demo (app 4830300, store date 24 July 2026), no official Android APK, Family Sharing is not two-player Atlas.
5. Version History — timeline spine 0.65 → room expansion → Doctor event → 0.99 → 1.0 hotfix.
6. Steam Status — wishlist, TBA, languages, adult store flags, Demo availability, and system-requirements summary links.
7. Dev Progress — Patreon milestone framing versus Steam Demo builds; what counts as new content.
8. Patreon vs Steam — why Patreon build numbers and Steam Demo 1.0 hotfix can diverge, and which string to trust.

Use Changelog when a skill name or timing suddenly disagrees with a guide. Use Version History when older videos disagree with your build. Use Demo Access when you need the legal install path. Use Platforms & APK when search results push Android APKs. Use Steam Status when you need store-facing facts for wishlisting. Use Patreon vs Steam when a Patreon post and your Steam install disagree.

Why Updates matters for a Demo wiki

Guides under Guides Hub and routes under Walkthrough Hub assume systems like softlock desks, nest growth, INT/STR spends, Clinic / Doctor pacing, and Security Room A / B. Those systems can stay conceptually stable while labels and timings shift. Updates pages are the honesty layer between wiki truth and todays build.

If Kitchen feels different after a patch, do not only reread Kitchen Route — also skim Changelog. If an old video shows missing Clinic content, open Version History. If the store page changed age gate text, open Steam Status.

Versioning mindset (0.65 → 1.0)

Community and build chatter spans early preview numbers through Demo 1.0. Exact strings change. Healthy player habits:

• Note your Steam build id / version string when a bug appears.
• Reproduce once after verifying locale tools (Locale Emulator).
• Separate detection-wait softlocks from true stuck states (Softlock Fixes).
• Re-check skill planner assumptions (Skill Planner, Skill Tree).
• Confirm hardware comfort on System Requirements before blaming content.

This hub will not invent fake patch dates. When official notes are thin, we describe classes of change and a dated spine rather than fake changelogs.

Steam and TBA framing

Wishlisting is the correct long-term action if the Demo’s stealth-nest loop clicked. Full Atlas content remains TBA until the store says otherwise. Pair status reading with buyer impressions in Demo Review and Pros and Cons. Official Demo install path: Demo Access.

Adult store flags

Expect adult-only discovery constraints on Steam. That is product reality, not a temporary bug. This wiki will not provide bypasses. If you are in the audience, configure store/filter settings yourself and proceed to systems guides. Character threat profiles: Characters Hub.

Languages

Plan around English and Japanese support contexts. If menus are unreadable on your Windows locale, fix that before filing broken Demo reports — see Locale Emulator and Keyboard Controls.

Recommended pulse ritual

After each Demo update:

1. Read Steam’s own notes if present.
2. Skim Changelog for drift classes.
3. Place the build on Version History if you care about historical context.
4. Confirm store facts on Steam Status.
5. Replay a Kitchen softlock drill before Laboratory pushes.
6. Resume linear progress via Demo Walkthrough.

Early preview context

Preview and impression videos help set expectations, but they age. Prefer current Steam build behavior over older footage when nest UI, Doctor events, or Security Room flow disagrees. Systems truth still lives in How to Play and map pages like Atlas Overview.

Bottom line

Updates Hub exists so the wiki can stay useful while Mozu Field and Shady Corner Games iterate the Demo. Treat TBA as TBA, treat 24 July 2026 as the Steam Demo store date, treat Demo 1.0 hotfix as the content checkpoint until Steam shows newer, and keep softlock / nest literacy sharper than rumor mill version numbers.
