About Fear Equation

The world is covered in fog. Most who enter the fog disappear, and those who survive say it brings their nightmares to life.



No-one knows where it came from, but they all have ideas. Some say it's an experiment gone wrong, others believe it's divine judgement. And you? All you know is that the Sun is rumoured to shine just over the horizon.

You are The Engineer. You have designed the perfect system: a train, sealed off from the fog, ready to rescue survivors and take them to salvation.

If only they'd listen...


Fear Equation is a turn-based strategy with rogue-like elements where you must take control of a modified freight train in an end-of-the-world scenario. The landscape has been overrun by a thick, deadly fog that manifests the nightmares of those inside it. Your survival depends on tactical planning and careful resource management.

As the Engineer, you'll need to rescue survivors, analyse their dreams and build defenses to protect them from their own imaginations. Complicating matters, passengers have their own theories as to how the fog was created and will form inter-carriage factions based on their beliefs.

Every game is unique and you can customise your Engineer to dramatically change how the game is played.


Your passengers bring their nightmares with them. When the fog attacks, it will make their worst fears come alive. Read your passengers’ dream logs to help prepare defenses.


The train needs resources and there's only one way to get them: send your passengers back out into the fog. Listen to radio broadcasts for hints and equip your scavengers well. But don’t stay too long because they’ll disappear into the fog.


Passengers will group into four factions based on where they think the fog came from. Different factions are associated with different nightmares, skills and concerns. You’ll need to maximise their talents, handle their disputes and meet their needs.


Create your own Engineer with special modifiers - both good and bad - that determine your individual train's starting conditions, overall difficulty and the different courses the game can take. Personalise your Engineer further by importing photos of yourself (or others) for use with your character.


Populate your train with passengers of your own design using the custom passenger creator. Name, vital statistics, occupation, factional tendencies and influence can all be modified. As with Engineer customisation, you can import photos from outside the game to give each passenger a life of their own.


Explore a richly detailed 3D cabin and interact with computers, train controls, maps and consoles. All interaction points feature an in-game manual so you’ll never get lost.



With squabbling passengers, limited resources and wandering foes including the cult-like "Fearless" and powerful military, the fog might be the least of your concerns...

Great game! ever since they updated the custom passengers from 15 to 150 this game rocks. also they fixed a lot of the issues with disappearing portraits and such which is great, so the game works pretty well. always been a fan of the game, just used to get so frustrated with the glitches and bugs. one thing I would like is an option that only allows the custom passengers to show up more often in the game, or an option that makes the custom passengers show up way more than the in game random people. Also, I know the fog is meant to be mysterious, but would be cool if there was more lore to this game and maybe some more mini events that give clues on what is actually happening, (unless I am just missing something I haven't seen yet). the Ending is cool, but would be cool if there was a bit more to the ending like some images depicting the new society that had been created by your passengers based on the type on factions there are. But, I get this is an old game, so I don't expect to much from the devs, just happy it actually got any updates at all. I would love to see this gem get more mainstream attention though, like the FNAF or SCP, this game deserves it.

I played this back when it first came out. After about 2 days of play, I got fed up and frustrated with the UI. This week, after almost 10 years, I decided to give it another try. Nope. Same deal. UI is horrible and after 2 days of trying to play, I gave up.

I really do love the atmosphere of this game its something I do come back to now and again, the claustrophobia feels both unnerving and comforting, the fact the only thing you see out the windows is fog or nightmares. However the exploration feels a little strange and needs getting used to. The diplomacy system is also really interesting but the only problem is I never have enough people to warrant it! Would love an updated sequel!

This is the kind of game that would make more money from advertisements on some kind of game portal on the internet. It really does feel like a point and click flash game with all of its pre-rendered content and simplistic game loop.

Another weird game from Screwfly Studios. I just finished my first game (restarted 2 times while learning) and I got a Poor score, so I have a good reason to try again! I had a great time with this game. I really like the quirky settings and sounds, their strange way of approaching game designs, ... (I hated the win music at the end of the game, what terrible sound quality on a terrible short loop) Game is good, stable, runs on Linux. Paid around 1 euro/hour now... Worth it! For some reason, the tutorial never got started on my laptop, but it did start on my desktop PC (both Arch Linux), but if you watch a bit of youtube and/or read the in-game manuals, you don't really need a tutorial imo. One thing I really don't like is that you can only save the game after the night. Once you initiate a new day, you need to completely finish that day to be able to save your day. Days aren't that long, but still... Can't wait to see what their next project will be.... I'm a great fan of both the 'Zafehouse Diaries', but not a fan of their 'Deadnaut' series. Maybe a quirky space sim?
