You're standing at the security desk. The buzzer rings. You look through the glass and see a guy who looks exactly like Kevin from 4C, except his left eye is migrating toward his ear. It’s the classic loop of That's Not My Neighbor, the indie horror hit that turned the mundane job of a doorman into a high-stakes game of "spot the eldritch horror." But after you’ve cleared the nightmare mode and mastered the basic identity checks, you start wondering: where is the That's Not My Neighbor downloadable content?
Honestly, the internet is a mess right now. If you search for DLC or expansions for this game, you’re going to run into a wall of clickbait YouTube thumbnails and sketchy "mod" sites promising things that simply don't exist in the base game. People are desperate for more. They want new monsters, new floors, maybe even a different setting. But the reality of how Nacho Sama—the solo developer behind this project—handles updates is a bit different than the typical AAA roadmap we're used to.
The Reality of Post-Launch Content
Most people looking for That's Not My Neighbor downloadable content are actually looking for the "Nightmare Mode" update. For a while, that was the "big thing" everyone was waiting for. It wasn't marketed as a paid DLC pack on a storefront like Steam or Itch.io; it was a massive functional update that fundamentally changed the difficulty and the visual horror of the game.
In the gaming world, we often conflate "DLC" with "paid expansions." For this specific title, the "DLC" experience is delivered through version iterations. If you're playing on version 1.1.0 or earlier, you're missing out on the core of what people consider the "extra" content. The developer has been pretty vocal on social platforms and the official Itch.io page about keeping the game focused. There isn't a massive season pass. There isn't a "Skin Pack 1." It's just a raw, evolving indie project.
The Nightmare Mode specifically added the "Nightmare" difficulty which introduces much more aggressive dopplegangers and a darker aesthetic. It's basically the unofficial DLC everyone was asking for. If you haven't touched the game since its initial viral explosion on TikTok and YouTube, you’re basically playing an outdated demo compared to what the current build offers.
Why "Mods" Aren't Exactly DLC
Let's get real for a second. If you see a video of a "SpongeBob SquarePants" doppleganger or a "Freddy Fazbear" trying to get into the building, that is not official That's Not My Neighbor downloadable content. It's the modding community.

Because the game is built in a way that is relatively accessible to those who know how to swap assets, there is a thriving underground scene of fan-made content. But here's the catch: downloading these can be a total gamble. Unlike official content from Nacho Sama, fan mods can break your save files or, worse, come bundled with malware if you're grabbing them from unverified Discord servers.
- Official Content: Comes directly through the Itch.io launcher or Steam update.
- Fan Mods: Usually found on sites like GameJolt or specialized horror mod forums.
- The Difference: Official content is balanced for the "lore." Mods are usually just for the memes.
It’s easy to get confused because the game’s art style is so distinct. A well-made fan mod looks almost exactly like the real thing. But if you're looking for the "true" experience, you have to stick to the official dev logs.
The Lore Expansion Everyone Missed
When we talk about That's Not My Neighbor downloadable content, we have to talk about the "D.D.D." (Doppleganger Detection Department). The recent updates haven't just added new faces; they’ve expanded the world-building. We now have more context on why these things are trying to get in.
There's a specific kind of storytelling happening here that mirrors games like Papers, Please. Every new document or "flavour text" added in an update functions as content. For instance, the addition of the "Chester" quiz and the secret encounters are essentially mini-DLCs tucked inside the main game. You don't pay $4.99 for them; you just have to find them.
Chester’s questions are a great example. It’s a side-quest that feels like a separate module. If you haven't encountered the hooded figure or tried to solve the underlying mystery of the 1955 setting, you're leaving about 30% of the game's current content on the table.

What's Coming Next? (Factual Speculation)
Is there a formal That's Not My Neighbor downloadable content pack on the horizon?
Based on the developer's history, the answer is "probably not in the way you think." Nacho Sama has shown a preference for "Major Version Updates" rather than modular DLC. However, there has been significant chatter about a mobile port and potential console expansions. When games move from Itch.io to consoles like the Nintendo Switch or PlayStation, they almost always launch with "Complete Editions." This usually includes all previous updates plus a little something extra—like a new floor or an endless mode.
If you’re hunting for "new" things to do right now, your best bet isn't a download button. It's the "Achievements" list. The developer added a series of badges that require very specific, often counter-intuitive playstyles. Getting the "Peaches" achievement or finding the secret "UFO" ending is the closest thing to a "Hidden Level DLC" currently available.
How to Get the Most Out of the Current Build
If you feel like you've seen everything, you probably haven't. The game uses a randomization seed that can be incredibly stubborn. You might go 50 rounds without seeing one of the rarer "perfect" dopplegangers.
- Check your version number. If you aren't on at least v1.2, you are playing an old game.
- Enable Nightmare Mode. If the screen isn't tinted and the monsters don't look truly horrific, you're still in the "tutorial" phase.
- Hunt the Secrets. There are specific phone numbers you can dial and specific ways to interact with the D.D.D. that trigger events most players never see.
The "content" is already there. It’s just buried under the difficulty curve.

Dealing With Fake "Download" Links
This is the boring but necessary part. Because the game is so popular, there are dozens of sites claiming to have "That's Not My Neighbor DLC Pack" or "Unlocked Premium Version."
Don't click them. Seriously.
The developer only distributes the game through official channels like Itch.io (and eventually Steam). There is no "DLC.exe" file that you need to run. If a site is asking you to fill out a survey to "unlock the new characters," it's a scam. The indie horror scene is notorious for this. Stick to the official dev blog on Itch.io to see when a real expansion or a sequel is actually dropping.
The Verdict on Extra Content
Basically, That's Not My Neighbor downloadable content doesn't exist as a separate purchase because the developer is still building the "base" experience into something much larger. It’s a work in progress that you’ve already paid for (or can get for a few bucks).
Instead of looking for a new download, try to break the game you already have. Find the secret characters. Try to get a perfect score on Nightmare Mode without using the folder. That's where the real "extra" gameplay lives.
Actionable Next Steps
If you want to ensure you have every piece of content currently available for the game, follow these steps immediately:
- Visit the official Itch.io page: Check the "Dev Log" section. This is where Nacho Sama posts every single change, no matter how small. If a new character is added, it will be listed there first.
- Verify your game files: If you downloaded the game months ago, delete it and redownload the latest archive. Indie devs often "silent update" small bugs or add rare easter eggs without a massive announcement.
- Master the "Chester" Quest: If you haven't earned the "Academic" achievement by answering the six lore questions, you haven't finished the game's current narrative content. Use the in-game clues—don't just look up the answers—to actually experience the depth of the world-building.
- Join the official Discord: This is the only place where you can get legitimate info on upcoming "DLC-style" updates directly from the source. It’s also the safest place to find vetted community mods if you really need a fresh coat of paint on your security booth.
The game is much deeper than a simple "spot the difference" puzzle, but you have to be willing to look past the surface to find the new stuff. Stop looking for a "Buy Now" button for DLC and start looking for the secrets already hidden in the hallways of your building.
