Signs of Life Alien Language: How to Learn Xenoid Script

The alien language is one of Signs of Life's more unusual progression systems. It is not a dialogue option you unlock by finishing a quest. It is a collection mechanic: scan the writing, build understanding, and eventually read the archives.

This guide explains where to find inscriptions, how the progression works, and what changes when you understand the Xenoid.

Every new inscription adds to the language.

What the language unlocks

The language is the key to the Xenoid side of the story. Once you understand enough:

• Xenoid dialogue becomes readable.
• AGIS can extract seven reusable archive records into the MEG.
• City exploration gains context; the rooms and objects stop being set dressing.
• The ending's alien perspective becomes clear.

The archives are the main reward. They explain Xenoid history, their relationship with Osiris and their view of the Hephaestus colony.

Where to find inscriptions

Inscriptions appear on:

• Xenoid city walls and monuments.
• Ruins and ancient structures.
• Alien machines and shrines.
• Story locations in the deep dungeon.
• New Earth shrines in the late-game areas.

The exact locations vary by world, but the pattern is consistent: if a structure looks alien and has a written surface, scan it. Do not wait for a quest marker.

How scanning works

1. Equip the MEG and use the scan function.
2. Aim at the inscription until the scan completes.
3. The MEG records the glyphs and adds to your understanding.
4. Repeat across different inscriptions.
5. Check the Codex tab for new entries.

Scanning is not a one-time interaction. Some inscriptions are part of a set; scanning the same wall twice does not help, but scanning a different wall in the same city does.

The progression curve

The game does not publish an exact number of inscriptions required. The practical curve is:

• Early: you recognise individual signs but cannot read sentences.
• Mid: you understand names, places and warnings.
• Late: you can follow dialogue and archive text.
• Complete: AGIS can extract the seven archives.

Do not expect a single city to complete the language. Explore ruins, cities and story locations across the world.

A scanning route

Phase 1: surface ruins

Start with the ruins near the main story path. They introduce the visual language and give you the first entries. Scan the exterior before entering; some inscriptions are easier to see in daylight.

Phase 2: deep dungeon

The dungeon beneath the bottom teleporter contains denser alien writing. This is where the language starts to feel like a system rather than decoration.

Phase 3: Xenoid cities

Cities are the richest source. Scan the public spaces, monuments and archives. The 1.0 layouts add more rooms and family spaces, which means more surfaces to scan.

Phase 4: New Earth

New Earth shrines and tunnels add late-game inscriptions. If you are hunting the last entries, revisit the shrines after the main story.

What AGIS does

AGIS is your AI companion and the narrative voice of the MEG. Once you understand enough of the language, AGIS can extract the seven reusable Xenoid archive records into the MEG.

The extraction is not a separate minigame. It is a story beat that turns your scanning work into readable archives. If AGIS is not offering the extraction, you have not reached the language milestone.

Language and the ending

The ending route runs through Xenoid territory. Understanding the language changes what you understand about the finale, even if the mechanical steps are the same.

If you rush the ending without scanning, you will still reach credits. You will miss the context that makes the Xenoid a civilisation rather than a enemy faction.

Tips for completionists

• Scan every new glyph before looting a room.
• Keep a checklist of cities and ruins you have cleared.
• Revisit cities after major story beats; dialogue may change.
• Use Comm Beacons to mark unscanned structures.
• Check the Codex after each session for new entries.
• Do not sell or discard archive-related items.

Common problems

Scanning does not progress. Make sure you are scanning a new inscription, not the same one. Different walls and monuments count separately.

AGIS will not extract the archives. You have not reached the language milestone. Scan more inscriptions in cities and story locations.

I missed a city. The MEG map and beacons help, but the game does not mark every settlement. Revisit the alien zones after the main story.

The language feels optional. It is optional for the mechanics of the ending, but it is the core of the Xenoid narrative. Treat it as the main story's second half.

Is it worth learning?

Yes, if you care about the story. The Xenoid are the most original part of Signs of Life's setting, and the language is how the game gives them a voice. If you only want combat and building, you can skip it, but you will experience a thinner ending.

The Xenoid guide→ covers their society and loot, and the ending guide→ covers the final route.

FAQ

How do you learn the alien language in Signs of Life?

Scan inscriptions in ruins, Xenoid cities and story locations. Each new scan adds to your understanding.

How many archives are there?

Seven reusable Xenoid archive records. AGIS can extract them into the MEG once you understand enough of the language.

Can I learn the language after the ending?

You can keep playing after the credits, but the language is part of the late-game route. It is easier to scan as you go.

Does the language affect gameplay?

It unlocks dialogue and archives. It does not change combat stats or recipes directly.
