This Legion Was Here walkthrough starts with the part every mission has in common: read the dossier, rebuild the target's face in the operating room, then survive the interview with the people who knew them. Each mission below lists who you are sent to impersonate, who does the questioning, and the dossier and interview answers that run decides.

More context

You play Legion, an agent who can change his appearance at will and takes jobs from everyone from the FBI and MI6 to ghosts and amusement-park mascots. Nothing in the game asks for quick reactions — controls are mouse or touch only — so the difficulty is entirely in the deduction.

How Each Legion Was Here Walkthrough Runs

  1. Study the dossier.

    Photos, newspaper clippings, biographical notes, letters and small everyday items hold the target's appearance and history. Some details are planted to mislead you.

  2. Rebuild the face.

    In the operating room you match the target from the evidence, choosing among more than 900 million combinations of age, hairstyle, nose shape and width, eye colour, eye shape and other facial structure. Every slider is a claim about what this person actually looks like, not a style preference.

  3. Survive the interview.

    Several people who knew the target fire multiple-choice questions about their past, habits, family and opinions while inspecting your face. Correct answers build credibility, a wrong answer or a face mismatch ends the run.

The Six Missions In The Campaign

The full game contains six contracted missions — Become Patrick, London Undercover, Neptune's Guest, The Big Day, Mafia Blues and Legion: Origins. Each one runs the same loop against a different dossier and a different cover identity, so no contract is mechanically harder than another.

The Big Day is the one job with its own pair of achievements, and it is a good second look if you want to see what a 100 percent run takes. If you are trying to work out which job closes the campaign and what counts as finishing the game, how the final mission ends covers that.

Who You Impersonate In Each Mission, And The Answers That Decide It

In campaign order, with the answers each run actually turns on:

  1. Become Patrick — you are Patrick himself, in person, for Alan Cotton. You are 36, so you turn 37; you are vegan, which the shopping list proves with the vegan cheese and plant-based everything on it; your last party was the Wild West, because the drawing shows you in a cowboy outfit. You spent last summer in Athens and grew up in the UK. Never admit to being a spy.
  2. London Undercover — you are Claude Roy, meeting Lydia Wu. You last saw her at Geneva airport, met her at a Paris university where you studied physics and chemistry, and your cover job is a bookseller. Your husband is Felipe DuPuit. Her real name is Madeline Zhou, her nickname is Maddy, she plays rock and her favourite band is Bark Bark Bark. Your last MI6 run-in was 2016.
  3. Neptune's Guest — you are Vulneek, passing as the clown Denis Laforge. The secret gesture is a closed right hand with index and middle fingers raised. Your troupe is Medori-Zoilonni and your colleague is Pizzoli. You cannot eat fruit, you hate anchovies, and you live in New York rather than next door. Neptunians read right to left, so on the Mount Rushmore postcard Lincoln is first, Roosevelt second, Jefferson third and Washington fourth. Never claim Centaurus or the Southern Cross, and your war cry comes out as Falruk.
  4. The Big Day — you are Ralf, a Jujuk performer, on a date with Helga. You are Sok to her Serena, you both posted your ads in the same issue of Jujuk Mag, and on your first date at Jujuk BurgerZ you both ordered MoroKetchup. Helga hates smokers, which is how you rule out the visitor who storms in wearing a Roomzy costume. The complete Big Day answer set is on its own page.
  5. Mafia Blues — you are Michael Lucci, in New York for the mob boss Andrea Torrelino. Your childhood love is Domiza of Foggia, she never married, and you last saw her in 1973. Your film is Deep Blue, your drink is whiskey, and you are far too tired of seafood to want any. Her favourites, which arrive as a mid-interview deduction, are lilacs, red, cherries and zucchini.
  6. Legion: Origins — you are Thomas, meeting Helena. The whole dossier is a pair of poems and a cut-out overlay, and the answers are fixed: Thomas, Helena, driving on the left, Pisces, blood type A, birdwatching, soccer with your foot, a cross tattoo on your right hand, crab with lemon and mayonnaise, red wine, Mozart, and a terror of clowns. The complete final mission answer set is on its own page.

The face each of those targets needs is on the face creation page, and the way the questions are built is on the interview questions page.

These answers are transcribed from the player-made Legion Was Here guide on Steam and cross-checked against the Chinese puzzle-flow guide.

Notes On Legion's Left Hand

The dossier is not reopened once you leave the briefing room, so anything you want to remember has to go onto Legion's left hand before you walk in. The hand is small, which means you have to choose what earns the space: hair, eye colour, nose shape, age range, the loved one you are impersonating, and the two or three biographical facts most likely to be asked about.

Two passes are worth it. Read the file once for the story, read it again to pull out the concrete traits, then write only those. How to weigh what is in the dossier covers the split between appearance cues, biographical cues and the small items that still decide a single answer.

Why Runs Fail And What Replaying Changes

A wrong answer blows the cover instantly: the people you are deceiving either kill Legion or call the operation off, and there is no dialogue option that lets you retry one line. Missions are replayable, though, and the set of biographical questions changes between attempts, so a failed run is information rather than a dead end — the second attempt with a fuller set of notes is usually the one that passes.

Credibility tops out at 100 percent, and getting there means matching every answer to the dossier facts, including details you only found by cross-referencing two documents. What the interview actually asks you explains how to prepare for the questions that decide that score.

Controls, Length And Replays

A full campaign is roughly 3–4 hours across the six missions. Because the loop never changes and the question sets rotate, extra time goes into reading and replaying rather than into execution: there are no timing checks, no stealth segments and no penalty for spending ten minutes on a dossier before you move a single slider.

Legion Was Here Demo Walkthrough: The Neptunian Cover MissionThe Legion Was Here demo walkthrough is worth playing before the full game: the free demo covers the tutorial plus one complete mission, and it uses the same face creator and the same multiple-choice interview as the paid campaign. Practising the loop here means the first contract in the full game is not your first look at any of the systems.Legion Was Here Big Day Mission: What It Is And What It UnlocksThe Legion Was Here Big Day mission is one of the six contracted jobs, and it carries the only pair of achievements that belongs to a single mission: **Jujuk In Love** for finishing it, and **Jujuk World Peace** for finishing it at 100 percent credibility. The name ties it to the Jujuk faction in the game's world, and mechanically it is the standard three-phase contract applied to its own dossier and its own cover identity.Legion Was Here Final Mission: What Ends The CampaignThere is no seventh mission waiting behind the last one. The Legion Was Here final mission question usually means two things — which job closes the game, and what counts as actually finishing it — and the answer to both is the same: the campaign is the six contracted missions, it closes with a credit sequence, and the campaign's own completion mark is **Legion Is Done**, which needs 100 percent credibility on every one of them.
