Amazon.com Inc. and Leyou Technologies Holdings Ltd will co-produce a video game based on “The Lord of the Rings.”

The Hong Kong-based game developer had announced plans for the free-to-play, online multiplayer game last year, and said on Wednesday that Amazon was joining the effort. Leyou will handle marketing and operations for the game in China and Taiwan, and Amazon will do those tasks for the rest of the world, the company said in astatement.

Amazon Studios is separately working on a television series based on J.R.R. Tolkien’s work, an effort to create a blockbuster that boosts interest in the $119-a-year Prime membership that unlocks access to Amazon’s original streaming content. Amazon has not set a release date.
