Ubisoft first announced that The Division developer Massive Entertainment would develop a game based on Avatar back in February 2017.
Here is an overview of the game, via Ubisoft:
Avatar: Frontiers of Pandora is a first person, action-adventure game developed by Massive Entertainment—a Ubisoft studio, in collaboration with Lightstorm Entertainment and Disney.
Built using the latest iteration of the Snowdrop engine, and developed exclusively for the new generation of consoles and PC, Avatar: Frontiers of Pandora brings to life the alluring world of Pandora with all of its beauty and danger in an immersive, open world experience.
In this new, standalone story, play as a Na’vi and embark on a journey across the Western Frontier, a never-before-seen part of Pandora. Explore a living and reactive world inhabited by unique creatures and new characters, and push back the formidable RDA forces that threaten it.
