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...
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.
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...
