Riptide GP: Renegade is celebrating the game’s 1 year anniversary with a sale. The game is currently $0.99 and so is its predecessor, Riptide GP2. While Riptide GP2 has been free in the past, this is the lowest price that Riptide GP: Renegade has ever been. The game is compatible with all Fire TV device models except the 1st generation Fire TV Stick. It works with either a game controller or remote.
