This is a full guide to Lost Wiki: Kozlovka, covering every report, important codes, and all endings. The game revolves around reading, connecting information, and using clues hidden in emails, attachments, and the database.
If you ever feel stuck, it usually means you missed a detail in an article, image, or attachment.
Lost Wiki Kozlovka Walkthrough Guide (All Reports + Endings)
At the beginning, you receive an email with a job offer and basic instructions.
What you should do first:
- Open the Database (globe icon)
- Open your Report (notepad icon)
There’s also a relationship tree in the bottom-left of the database. This becomes extremely important later, so get used to checking it.
Your first report is simple. Just explore links and understand the structure. After finishing it, you’ll be asked to dig deeper.
Unlocking Your First Restricted Link
You’ll notice some links are locked. The first one you need is:
- Zarnavian Government
- Code: 1991
Once unlocked, read everything carefully, especially images. Use that information to complete your report.
At this point, you’ve basically finished the tutorial phase.
The Real Brief
Now the actual investigation begins.
You don’t need restricted links here, but you should:
- Go through every hyperlink
- Bookmark modified articles (they will say they’ve been updated)
The emails suggest someone disappeared in the 90s, so most relevant information is from that time period.
Dig Deeper
You get access to a new restricted link:
- Kozlovka Tragedies
- Code: 7328
This section is more about reading carefully than solving puzzles.
Key tip:
- Use the Agriculture section image to identify the correct tragedies
Select the right events based on what you find in articles and visuals.
Redacted Bypass (New Mechanic)
This introduces one of the most important systems in the game.
To unlock it:
- Click the mushroom icon (top-left) → gives system code
- Check the email attachment → gives area code
Final code:
- 342451
Once inside:
- Focus on redacted (hidden) information
- This is where major story connections start forming
Bookmarking earlier helps a lot here.
Family Ties
You now unlock another restricted section:
- Kozlovka Town Ledger
- Code: 3156
How it’s solved:
- The Town Hall code is NW6
- Using earlier clues, this converts into the final code
Important here:
- Use Redacted Bypass data
- Carefully examine images and records
Hidden Sister
Next restricted link:
- Dragunov Family
- Code: 1512
This section focuses heavily on:
- Family relationships
- Newly revealed information in redacted files
You’ll need to combine:
- Email attachments
- Redacted details
- Database entries
Conspiracy
At this point, the game expects you to use everything you’ve learned.
Important focus:
- Revisit earlier information
- Check Atyla Dragunov’s redacted data
Half of the answers are things you’ve already uncovered.
You’ve Done Enough
This is where the story starts making sense.
Key detail:
- Pay attention to who is sending the emails
- The letter “V” becomes important
Analyze each character and their connections.
Wrong Assumptions
You finally discover who hired you.
This section is straightforward:
- Mostly confirming what you already know
- Less puzzle-solving, more recognition
Finish What We Started
This part heavily revolves around:
- Jan Dragunov
Everything connects back to him, so use:
- Previous reports
- Attachments
- Relationship map
No Subject
Very simple section.
By now:
- You already have all required knowledge
- Just apply it directly
Contract Terminated
A new sender appears, but:
- No new major information
- Just reusing existing knowledge
Jan Dragunov (Reconstruction Phase)
From here on, you are essentially reconstructing the full story.
Use:
- Volha’s attachments
- One at a time
Focus on accuracy rather than guessing.
Stubborn as a Rock
Use the first attachment from Volha.
This is about:
- Rechecking earlier conclusions
- Making sure everything lines up
Continue
Use the second attachment.
Some parts may require guessing, but:
- Start with what you are confident about
- Then fill in the rest logically
Keep Going
Use the final attachment.
At this point:
- Everything should connect
- The story becomes clear
Well Done
This section is very direct.
You’ll notice:
- Answers feel obvious
- Because you’ve already built the full picture
My Father (Final Report)
This is the last report.
No complex solving here:
- Just conclude everything you’ve learned
- Tie all relationships and events together
All Endings Explained
You have three different endings depending on your final choice.
Ending 1 – Publish the Article
You expose the truth about Kozlovka.
Outcome:
- The mystery is revealed
- But you included redacted information
- You are arrested
Ending 2 – Delete the Evidence
You follow Jan’s instructions.
Outcome:
- All evidence is erased
- The truth remains hidden
- Kozlovka’s tragedies continue
Ending 3 – Burn the Tree (Best Ending)
You go to Kozlovka and destroy the Draken Oak.
Outcome:
- You fulfill Volha’s goal
- The cycle of tragedies ends
- Kozlovka is finally saved
This game doesn’t test speed — it tests how well you connect information. Once you start seeing those connections, everything becomes much easier to solve.
