Assassin's Creed: Rogue is the eighth main game in the historical series. It is the sequel to Assassin's Creed IV: Black Flag from the year before. It also acts as a prequel to Assassin's Creed III and the game's final mission is a prologue to Assassin's Creed: Unity, which was released simultaneously. Most of the gameplay and design are similar to the sandbox environment of Black Flag as the game combines exploration on land with ship-based naval exploration and battles.
