Alien Invasyndrome Map Hub
Deck layout, key rooms, and stealth routes on Atlas.
This Map Hub is the navigation spine for Alien Invasyndrome Demo on Steam (app 4603980). You play a weak alien larva aboard the exploration vessel Atlas. The full release is TBA; the Demo already exposes enough layout to learn deck flow, room pressure, and nest logistics without memorizing every vent by accident.
Content note: the game is 18+ adult stealth-action. This wiki stays mechanical—routes, detection risk, softlocks—not explicit scene writing.
What this hub covers
Use the three child pages as progressive detail:
- Atlas Overview — ship premise, Top / Middle / Lower deck roles, how vents and shadows connect risk.
- Decks — vertical movement habits, when to change layers, and how patrol density shifts between decks.
- Key Rooms — Kitchen, Clinic, Laboratory, Cafeteria, and Security Room (routes A/B) with practical approach notes.
- Middle Deck Loop — repeatable Middle-deck patrol drills between Kitchen comfort and Lab/Security pressure.
If you are still learning the loop, pair map reading with How to Play and Stealth and Detection. Nest placement decisions belong in How to Nest and the Nest Checklist.
Atlas in one paragraph
Atlas is a cold research ship framed as humanity’s long-shot vessel. In play, that lore mostly means corridors, service furniture, and crew patrol loops. Your larva starts fragile: open floors punish greed, desks and shadows buy time, and a failed detection can cost roughly a minute of forced hiding before the run feels usable again. Softlocks under desks are a real Demo hazard—treat furniture as cover with an exit plan, not a permanent pocket. Details and recovery steps live in Softlock Fixes.
How to read the ship for stealth
Think in three layers:
- Deck identity: Top, Middle, and Lower are not cosmetic skins. Patrol timing, room purpose, and vent usefulness change by layer. The Decks page is the habit guide.
- Room jobs: Kitchen and Cafeteria are traffic hubs; Clinic and Laboratory are tighter experiment spaces; Security is a chokepoint with split approaches. See Key Rooms.
- Nest radius: Nesting is not only a skill decision. Room choice affects how often you cross open sightlines while dragging progress back to safety. Cross-check Evolution Paths and Early Build before you commit to a distant nest.
Recommended study order
- Skim Atlas Overview once so deck names mean something.
- Run a short Demo session focusing only on surviving Middle-deck corridors — or drill Middle Deck Loop for timed patrol practice.
- Open Key Rooms and mark Kitchen → Clinic/Lab → Security as your mental path.
- Follow Kitchen Route and Security Routes for concrete pathing.
- Finish with Demo Walkthrough when you want an end-to-end Demo clear, including boss context from How to Beat Boss.

Demo vs full release mapping
Demo coverage currently emphasizes approachable Middle-deck spaces and Security pressure; Lower-deck expansion is part of the developer roadmap language around finishing the Demo and then preparing store presentation. Treat any incomplete lower areas as provisional. Do not invent room names that are not in current Demo routes. Wishlist the Steam page for TBA full-release notices from Mozu Field / 百舌鳥 and publisher Shady Corner Games.
Practical map checklist
- Name the three decks out loud before a run.
- Memorize one safe desk-adjacent hide per key room, plus an exit.
- Know which Security approach (A vs B) you are practicing before you commit.
- Never soft-reset under furniture without checking Softlock Fixes.
- After a detection, wait out the penalty instead of force-pushing the same corridor.
- When routing feels stable, spend points via Skill Tree instead of improvising every fight.

Frequently Asked Questions
Quick answers to common Alien Invasyndrome questions.
How many decks does Atlas have in Alien Invasyndrome?
The ship is organized as Top, Middle, and Lower decks. Demo access may emphasize some layers more than others; see Decks and Atlas Overview for Demo-safe expectations.
Which rooms should I learn first?
Start with Kitchen and Cafeteria traffic, then Clinic and Laboratory corners, then Security Room routes A/B. The Key Rooms page lists approach notes for each.
Where should I go if I keep getting softlocked under desks?
Open Softlock Fixes in Guides, then practice room exits from Key Rooms. Desks are temporary cover, not permanent storage.
Is the full Atlas map in the Demo?
No. The Demo is a slice; full release is TBA. Use Steam wishlist updates from Mozu Field and Shady Corner Games for expansion notes.
