Riptide GP2, one of the highest rated games for the Fire TV, is Free for a limited time. This deal is part of Amazon’s Year-End free app bundle which includes over $110 in free paid apps. The game has been free twice before, but is regularly $1.99. This is one of the more graphically intense games available for the Fire TV, which is why it’s not compatible with the Fire TV Stick. It works with both the game controller and remote, so head on over to Amazon and grab it before the sale ends.
