The game takes place in a post-apocalyptic Earth where dimensional rifts have torn open, bringing magic, monsters, and alien technology to the planet. This fusion of genres allows players to encounter everything from high-tech cyborgs and vampires to dragons and ancient deities. Rifts offers an unprecedented amount of flexibility for creating characters and stories. You can be anything from a power-armored soldier to a mystic who commands the forces of magic, or even a dimensional traveler with access to alien technologies.
