STALKER 2 Secret Ending Guide: How to Unlock the Secret Kaimanov Ending in Pripyat
If there is one thing S.T.A.L.K.E.R. 2: Heart of Chornobyl does exceptionally well, it is making you question whether any decision you make is actually the right one. The Zone has never been a place where morality comes with clean answers, and the game’s endings are a perfect extension of that idea.
The Kaimanov Ending, also known as Project Y, is probably the ending I would recommend seeing if you are interested in the deeper lore rather than simply wanting to finish the story. It is not a traditional “good ending,” and calling it secret is slightly misleading because the game does have four main endings. Still, compared with the more obvious faction routes, Project Y feels like the game’s strangest and most revealing conclusion.
What makes it particularly interesting is that you don’t unlock it by making one magical choice at the very end. Instead, your route is gradually shaped by three important decisions. Miss one of them, and you can end up watching a completely different version of the finale.
The three missions that matter are Subtle Matter, Dangerous Liaisons, and The Last Wish. The required choices are:
| Mission | Choice For Project Y |
|---|---|
| Subtle Matter | Life is for the living |
| Dangerous Liaisons | Escape |
| The Last Wish | Lower the gun |
Why the Kaimanov Ending Is Worth Seeing
I have always liked the endings in STALKER games that leave you sitting there for a few minutes after the credits, trying to figure out what you just witnessed. Project Y absolutely belongs in that category.
Unlike the Ward ending, which is built around controlling the Zone, or the Strelok ending, which is much more focused on containing and protecting it, Kaimanov’s vision is something much more disturbing. The Zone is no longer treated as a problem that humanity can simply seal away.
The Project Y conclusion pushes the idea that the Zone’s influence could become something global.
That makes it particularly fascinating from a lore perspective. You’re not simply deciding who gets control of the Exclusion Zone. You are effectively deciding what humanity’s relationship with the Zone will look like in the future.
And yes, the consequences are about as STALKER as you could possibly imagine.
Step 1: Choose “Life Is for the Living” in Subtle Matter
Your first major checkpoint comes during Subtle Matter, when Skif is working with the visiograph at Orbita Station.
Eventually, Scar confronts you. This is the moment where the game starts separating the different ending routes.
If you’re going for Project Y, select:
“Life is for the living.”
This is an important choice because it moves you away from the Spark route. Choosing the alternative associated with Scar and the Shining Zone can lock you out of the Strelok/Kaimanov branch.
Personally, I think this is one of the game’s better examples of how its ending system works. The dialogue itself doesn’t scream, Congratulations, you’ve just selected Ending #4. You’re simply responding to Scar based on what you believe Skif would actually say.
Then the consequences arrive.
Scar and the Spark forces become hostile, meaning your trip through Orbita Station can become significantly more uncomfortable. If you’re used to talking your way through certain encounters, don’t expect that luxury here.
My Advice
Make a manual save before starting Subtle Matter.
There is absolutely no reason to replay a huge portion of the late game just because you clicked the wrong dialogue option. STALKER 2’s ending system is surprisingly unforgiving about these particular choices.
Step 2: Escape From Korshunov in Dangerous Liaisons
The second major decision happens during Dangerous Liaisons.
This time, you’re dealing directly with Colonel Korshunov and the Ward. Eventually, Skif is captured, and the game gives you another extremely important choice.
You will have the option to cooperate with the Ward or attempt to get away.
For Project Y, choose:
“Escape.”
This decision keeps you out of the Ward ending. Selecting “I’m not your enemy” instead commits you to the Ward path.
This is where the late-game atmosphere starts getting particularly nasty. By this point, you’re effectively refusing to belong to either side.
Scar doesn’t want you.
Ward doesn’t want you.
And you’re still walking toward the most dangerous part of the Zone.
That is exactly why this route feels so appropriate for Skif. He isn’t becoming the champion of one faction. He’s becoming the person caught between several competing visions of what the Zone should become.
Step 3: Lower the Gun During The Last Wish
This is the choice that actually separates the Kaimanov ending from the Strelok ending.
During The Last Wish, Skif eventually confronts Dr. Kaymanov in the Red Forest. Strelok has made his position clear: the doctor must die.
At this point, the game gives you the choice you’ve been building toward.
For Project Y, select:
“Lower the gun.”
Do not choose Fire.
If you shoot Kaymanov, you will move into Strelok’s ending instead. If you lower your weapon, Kaymanov survives and the Project Y route continues.
And honestly, this is my favorite choice of the three.
Not because sparing Kaymanov is necessarily the morally correct decision. It isn’t that simple. What makes it interesting is that you’re rejecting Strelok’s certainty.
Strelok believes the Zone is too dangerous to leave alone.
Kaymanov believes the phenomenon has another future.
Skif, by lowering the weapon, effectively chooses to see what happens when Kaymanov’s vision is allowed to continue.
That’s a pretty terrifying experiment.
The Project Y Finale Explained
Once you’ve made the three correct choices, you eventually reach the final sequence and the game’s conclusion begins to diverge from the Strelok route.
The important difference is that Kaymanov’s plan survives.
Skif enters the O-CTA pod, and the consequences of Project Y begin to unfold. Instead of the Zone simply remaining an isolated phenomenon around Chornobyl, its influence starts spreading beyond the traditional boundaries of the Exclusion Zone.
The ending depicts multiple Zones appearing around the world, suggesting that the phenomenon is no longer something humanity can contain in one location.
And this is where the ending gets genuinely uncomfortable.
Imagine the world outside the Zone suddenly having to deal with the same things stalkers have spent years learning to survive:
- Anomalies appearing far beyond Chornobyl
- Dangerous radiation zones becoming a global problem
- Mutants and other Zone-related threats escaping the traditional boundaries
- Entire regions potentially being transformed by anomalous activity
- Humanity being forced to adapt to a world where the Zone is no longer geographically isolated
It feels less like an ending and more like the opening chapter of an entirely new STALKER universe.
Why Project Y Feels Like a Possible Future for STALKER
This is where I think the Kaimanov ending becomes especially interesting.
A lot of game endings are designed to close the door on the story. Project Y does almost the opposite.
It opens an enormous door.
If the Zone can begin appearing in different parts of the planet, future stories don’t have to remain limited to the familiar Chornobyl landscape. A future STALKER game could theoretically explore completely different regions affected by the same phenomenon.
That’s probably why this ending sticks with people.
The original Zone is iconic, of course. But the idea of several Zones appearing around the world is almost too good of a setup to ignore. It gives the developers an enormous amount of freedom if they ever want to expand the setting.
Project Y vs. Strelok: The Choice That Actually Matters
The easiest way to understand the two endings is to look at the final decision.
| Route | Subtle Matter | Dangerous Liaisons | The Last Wish |
|---|---|---|---|
| Strelok | Life is for the living | Escape | Fire |
| Kaimanov / Project Y | Life is for the living | Escape | Lower the gun |
Everything before that final confrontation essentially puts you into the same late-game branch. The decision involving Kaymanov is what separates the two conclusions.
That makes a save before The Last Wish particularly valuable if you’re interested in seeing both.

Survival Tips Before Entering the Endgame
There is one thing I would definitely recommend before committing to this route: prepare like you’re expecting the Zone to hate you personally.
By this stage, you have fewer friendly options available, and several encounters can become much more hostile depending on your previous choices.
A few preparations are worth making:
- Stock up on ammunition. Late-game fights can burn through more rounds than you expect.
- Carry anti-radiation supplies. Don’t assume you can simply sprint through hazardous areas.
- Upgrade your armor. Anomaly and radiation resistance can be more valuable than simply stacking conventional protection.
- Keep healing items ready. Emission-related chaos is not the time to discover that your inventory is empty.
- Create manual saves. Seriously. The ending choices are too important to leave to autosaves.
I would also avoid spending every last resource before the final sequence. STALKER 2 has a habit of making you think you’ve reached the end of a difficult section and then immediately throwing something worse at you.

Final Verdict: Is the Kaimanov Ending the “True” Ending?
I wouldn’t call Project Y definitively canon unless GSC says so. The game gives you four different conclusions, and the existence of multiple endings is part of what makes the story work.
But if you’re asking me which one is the most interesting to experience, Kaimanov’s ending is right near the top.
It doesn’t simply answer what happens to Skif.
It asks a much bigger question: what happens when the Zone stops being a contained mystery and becomes a global reality?
That is a fantastic STALKER question because there isn’t an easy answer.
The Kaimanov ending doesn’t feel comforting. It doesn’t feel heroic. It doesn’t even feel particularly safe.
It feels like the Zone has finally won.
And honestly, that is exactly why I think Project Y is worth unlocking.
If you’re planning a second playthrough, make a save before Subtle Matter, follow Life is for the living → Escape → Lower the gun, and let the game take you down the rabbit hole. The final result is one of the strangest pieces of STALKER 2 lore you’ll see—and potentially one of the most important setups for where the series could go next.
