Alien Invasyndrome Skills Hub

This Skills Hub organizes progression for Alien Invasyndrome Demo (Steam 4603980). You begin as a weak alien larva on Atlas. Nesting, stealth, and the skill tree turn that larva into a ship-threatening organism. Full release is TBA; Demo systems already expose INT/STR-style investment, evolution branching, and early-build decisions worth planning instead of button-mashing.

Content note: 18+ adult stealth-action. Pages here discuss mechanics and tradeoffs, not explicit scenes. Developer Mozu Field / 百舌鳥; publisher Shady Corner Games.

Child pages

1. Skill Tree — how the menu works, what to unlock first, WIP quirks, featured deep dive.
2. Evolution Paths — how actions push different growth directions and when to commit.
3. Early Build — Demo-first investment order with gameplay video context.

Interactive planning belongs in Skill Planner. Nest readiness belongs in Nest Checklist. Detection patience belongs in Detection Timer.

Progression fantasy vs Demo reality

The fantasy is total ship takeover. The Demo reality is shorter: learn stealth, secure nest cycles, buy skills that reduce coin-flip peeks, then contest Security and later pressure. If you skip map literacy, skills only make your mistakes louder. Read Map Hub, especially Key Rooms and Decks, in parallel with this hub.

INT / STR as a decision frame

Treat INT and STR as planning labels for how you want captures and positioning to feel:

• INT-leaning choices usually support information, setup, and safer engagement timing.
• STR-leaning choices usually support commit windows, pressure, and finishing routes when you already have position.

Exact node names can shift while the skill menu is marked WIP in places—players have seen odd “learn again” UI states that should be ignored. Build around roles, then confirm nodes in your Demo build via Skill Tree.

Recommended learning path

1. Survive without skills: How to Play + Stealth and Detection.
2. Establish nest loop: How to Nest.
3. Open Early Build and spend the first cluster of points with intent.
4. Use Skill Planner to lock a second-stage plan before Security.
5. Execute Security Room / Security Routes.
6. If evolution choices appear, decide with Evolution Paths rather than vibes.

Skills and the map commute

A strong node does not erase a bad nest commute. If every return crosses Cafeteria open floor, buy stealth reliability before vanity damage. Room context:

• Atlas Overview
• Kitchen Route
• Characters Hub for patrol pressure that your build must respect

Softlocks under desks are not fixed by STR. They are fixed by exit discipline and Softlock Fixes.

Skills and Demo clear order

When you want an ordered clear rather than theory, jump to Walkthrough Hub and Demo Walkthrough. Boss context after Security pressure: How to Beat Boss. Version quirks: Updates Hub. Expectation setting: Review Hub.

Investment rules of thumb

• First points buy survival consistency, not highlight clips.
• Do not respec mentally every death; change one variable at a time.
• After a detection, wait the ~1 minute hide tax—skills are not a skip button.
• If Locale Emulator / JP UI confuses labels, fix controls first via Controls Hub.
• Revisit this Skills Hub after each Demo patch in case node order shifts.

Closing

Skills are multipliers on map knowledge. Use this hub to choose a growth identity, spend with a checklist, then return to Atlas routes with a larva that matches the plan. Wishlist Steam for TBA full-release skill expansions rather than assuming Demo nodes are final.
