Legion Was Here Complete Walkthrough: All Missions & Ending

Complete all six Legion Was Here missions with dossier clues, answer facts, successful actions and the full ending route.

IndieTome

This route combines the complete six-mission playthrough with the official game text and the existing visual references. It is written as a solution, not a transcript: presenter commentary, repeated attempts and dialogue that does not affect the route are omitted.

Most missions can draw from alternate questions and clue sets. Memorize the fact behind an answer rather than its position in the menu. Recheck the documents in your current case whenever the offered wording differs from the examples below.

1. Become Patrick — open complete solution

Objective

Impersonate Patrick for Alan Cotton's training exercise and finish the conversation without admitting that you are Legion.

Dossier and disguise

• Use the beach photograph and its reverse, the October sketch, the blond dye and the shopping list. Match Patrick rather than Alan Cotton.
• The usable profile is a mature 37-year-old with blond curly hair, green eyes and a vegetarian shopping pattern. The direct images decide the remaining facial parts.

Answer bank

• Last summer: Athens.
• Age at the approaching birthday: 37.
• Last birthday theme: the Wild West.
• Birthday meal: grilled corn on the cob and red beans.

Successful route

• Greet Alan as Patrick and stay in character; every option that insists you are Legion loses credibility.
• Answer the four memory checks with the facts above. A correct face and conversation produce 100% appearance and behavior.

Story result

• Alan accepts the disguise and spends the evening reminiscing with the person he believes is Patrick. The apparent tutorial is deliberately reinterpreted by the final mission.

2. London Undercover — open complete solution

Objective

Become arms dealer Claude Roy, win Lydia Wu's trust on Lambeth Bridge, then neutralize her before the nuclear purchase can proceed.

Dossier and disguise

• Cross-check the damaged 2016 MI6 sketch, the childhood advertisement, the clinic file and the post-operation X-ray. Use the post-operation nose, not the childhood feature.
• Write the cover identity separately: Julien, King's Bookstore, husband Felipe, San Francisco residence, Miranda Clinic, and the 2016 MI6 arrest in London.

Answer bank

• The previous meeting was one year ago at Geneva airport.
• Roy and Wu first met around age 20 at university in Paris and studied physics and chemistry.
• Roy's cover work is bookselling/publishing; Felipe is his husband.
• Wu's surname is Wu and her preferred music is rock.
• When the real Roy arrives, deny knowing him and let Wu test the shared memories.

Successful route

• Keep the last meeting separate from the first meeting; the location, age and studies answer different checks.
• After Wu accepts you as Roy and has the bandaged man removed, wait until she reaches toward the bag, then take the mission action to neutralize the target.

Story result

• The actual Claude Roy reaches the bridge, but the reconstructed identity knows Wu's memories better than he can prove them in the moment. Wu removes the real man and gives Legion the opening to complete the assignment.

3. Mafia Blues — open complete solution

Objective

Pass as the recently deceased Mickey Lucci, enter Napoli and eliminate mafia boss Andrea Torrelino before he orders the rival-family killings.

Dossier and disguise

• Combine the OceanWorld postcard, caricature and surveillance image with the letters from Foggia. Mickey is elderly; the recent caricature and current evidence take priority over old descriptions.
• Keep these names on the hand: father Ettore; brothers Antonio and Mattia; childhood love Domizia (Domi). Also note Alan Cotton, bourbon and Foggia.

Answer bank

• Recent trip: Seattle's OceanWorld; the caricature was drawn there and Mickey is tired of seafood.
• Family home: Foggia. Mattia travels as a pilot. Favorite actor: Alan Cotton. Preferred drink: bourbon.
• Childhood love: Domi, short for Domizia; their last meeting was in 1973 and she never married or had children.
• The first flower question intentionally leads into the ghost scene. After Domizia writes the logic on the hand, use lilac, red, cherry and zucchini.
• If a later drink variant asks for the celebration choice, use red wine.

Successful route

• Answer Torrelino's opening questions with the family and OceanWorld facts. Do not panic when no flower can yet be proven; that beat summons Domizia.
• Use the new hand notes for the four preference deductions. When Torrelino turns toward the bar, neutralize him and leave through the planned route.

Story result

• Domizia's ghost reveals that Mickey's crimes kept them apart after death and helps Legion kill the man who used him. Her choice costs her heaven but lets her reunite with Mickey.

4. The Big Day — open complete solution

Objective

Replace Ralf Sullivan at his wedding to Helga, complete their shared vows and defuse Alex's interruption.

Dossier and disguise

• Identify Ralf and Helga through the Jujuk Mag ads, colleague and birthday photos, tattoos, comic, chocolate wrapper and both sides of the BurgerZ receipt.
• Ralf is the young blond man with buck teeth and no facial hair. The completed route establishes a four-year relationship, the BurgerZ first date and matching MoroKetchup choices.

Answer bank

• Reason for being late: work held Ralf up at Jujuk Park.
• Vow pairs that may be drawn: Mako with Lalak; Lord Ramos with his cape; Sok with Lalak.
• Their paths were linked by ads in the same Jujuk Mag issue. The first meeting/date was at Jujuk BurgerZ; another variant asks for the same fries sauce.
• Food lines may use the Mako Max chocolate bar or the Lilik Burger Maxi Cheese, matching the displayed half of the vow.
• The intruder is Alex; he has obsessed over the missed match for four years and works at Jujuk BurgerZ. Refute his claim by pointing out that Helga hates smokers.

Successful route

• Follow Helga's half of each vow and select the matching Jujuk reference instead of guessing from real-world logic.
• After Alex leaves, continue the ceremony and kiss Helga when prompted. A wrong ear can reduce appearance while the route still succeeds, so use the clearest portrait for that part.

Story result

• Helga rejects Alex's claim that she should belong to him and states that she chose Ralf. The wedding continues; the resolution comes from her decision, not a contest between the two men.

5. Neptune’s Guest — open complete solution

Objective

Use Vulneek's human cover to infiltrate the Neptunian cell at Mount Rushmore, secure the detonator and stop the bombing.

Dossier and disguise

• Link the medical examination, interview, circus material, restaurant clues and the right-to-left monument note. Rebuild Vulneek's human disguise, not his gaseous body.
• The case can swap paired clues and questions. Match the secret sign and cover-life answer to the documents in the current dossier rather than relying on one replay.

Answer bank

• Verified sign variants include a right fist with index and middle fingers raised, or the alternate sign supported by the current clue sheet.
• The completed route explains the delay through the New York cover, keeps the costume on because of brown spots, and keeps speaking human until the Earth mission is finished.
• Circus colleague: Pizzoli. Food route: Trattoria Napoli/Italian food. Read the presidents from the Neptunian direction before choosing Lincoln or Roosevelt.
• Tell the ranger you are amateur astronomers. Choose a valid current sight such as Ursa Major, then use the thoughtful answer about why people seek meaning in extraterrestrial life.
• Accept the detonator with the Martian joke when that option appears.

Successful route

• Maintain the alien cover until the ranger leaves to call his estranged daughter. The cell then reveals four bombs and hands Vulneek the detonator.
• Let the three Neptunians carry the charges to the monument, then activate the detonator at the final prompt.

Story result

• The ranger's detour becomes a brief story about grief and reconciliation. Once he leaves, the terrorists trust Legion with the device that makes their own defeat possible.

6. Legion: Origins — open complete solution

Objective

Reconstruct Legion's original face and life from the accumulated fragments, then convince the family at Saint-Martin Street that Thomas has returned.

Dossier and disguise

• Assemble the red fragments from earlier cases and revisit the film page, Mount Rushmore image, old photographs, theme-park material, poem and the hand used for notes.
• The recovered profile is Thomas, age 33, from the United Kingdom. His wife is Helena and they have two children. The visual puzzle supplies the exact original face.

Answer bank

• Identity: Thomas; address the safety check as protecting Helena and the two children—the three people inside.
• Origin: United Kingdom; accepted habit variants include driving on the left or afternoon tea. Blood type A; zodiac sign Pisces.
• Favorite sport: football. Hobby: birdwatching, so take binoculars. Tattoo: a cross/X on the right hand.
• Favorite meal: crab with lemon and mayonnaise. Drink: red wine. Phobia: clowns.
• Favorite music: Mozart's Symphony No. 40. The furry pet is a mouse; choose cheese for its present.

Successful route

• Knock only after every face clue is resolved. Give Thomas's name, then answer the identity checks from the recovered profile; the exact subset can change between attempts.
• With the correct face and facts, Helena opens the door and invites Legion inside. The credits begin after the homecoming.

Story result

• Alan reveals that he too was a manufactured shapeshifter and that Patrick was his lost original identity. Seeing Legion wear Patrick's face restored his memories. He returns the same chance to Legion by recovering the evidence of Thomas's life.
• The finale mirrors the tutorial: the method once used to become somebody else is used to reclaim a self. The successful route ends with Legion accepted by his family.
