Fear Equation [official site] is a game set aboard a train and that train is one of the last safe havens in a world consumed by a terrifying mist. You play as the engineer and as you ride the rails, you’ll attempt to pick up survivors, scavenge supplies and survive the dark. The mist manifests the fears of your passengers, so you’ll have to monitor their nightmares in order to figure out what each night may bring. Oh, and those survivors will form factions based around their beliefs about the mist’s origins and purpose. Sounds great, right? There’s a catch.
