Spirits of the Realms is an augmented reality (AR) game developed by Guardians of Earth (GoE). It can be played as a stand-alone game, or integrated with QuestaGame.

Spirits of the Realms is a friendly competition between six alien spirit civilizations who have come to Earth to earn the right to become the protector spirits for the planets species - across all the Nature Realms. Players earn points by successfully identifying species they find in through the AR view. The game really comes to life within GoE Nature Realms, where there are big points multipliers on offer - and higher still for Realms with big BioScores!
