Traveling through a barren, otherworldly wasteland, the Infinity Train is full of puzzles and perils. For those in mental turmoil, they can climb aboard and suddenly find themselves wandering its length where each car is a whole other world. Each passenger has his or her own story that led them onto the train, but once aboard, the goal is both simple and difficult: by solving the mysteries of the train and interacting with its strange denizens, solve one's own mental troubles and through it hopefully find their way off the train.
