From the back of the book:
New Horizon is a science fiction world which holds the soul of a fantasy world's loose and inventive play style and its sense of exploration and wonder. It's a brand new world, just waiting for you to explore it!
New Horizon is a campaign about the ultimate destiny of the abstracted concept of humanity. Not limited strictly speaking to humans, the story is designed not just to explore humanity as we know it, but the many different directions it can possibly go. If you enjoy role playing and science fiction, but have been turned off by the restrictive or fantasy, then join New Horizon and be part of a new world beyond your imagination. The campaign is set across a vast and varied world, with terrains both familiar but refreshing and new, to completely alien in nature. From urban jungles to mountain passes of living crystals. From deep tropical mangroves to bio-luminescent subterranean fungal forests.
New Horizon is a table top RPG, like many other popular franchises such as D&D or Shadowrun. While the D20 tabletop system used by D&D is the most popular, New Horizon uses an exciting new system called Vo|t. You only need two D20 dice with Vo|t.
