Assassin's Creed Origins is an action role-playing video game played from a third-person perspective. Players complete quests—linear scenarios with set objectives—to progress through the story, and can freely roam the open world environment on foot, horseback, camel-back, horse-drawn vehicles or boat.[1][2] The open world includes much of Ancient Egypt, featuring vast deserts, oasis, lakes and ancient cities such as Alexandria and Memphis.[3][4] The game's main character, Bayek, can dive underwater and explore the lakes and the rivers, the first instance of underwater exploration in the series since 2013's Black Flag.[5] As the players explore the world, they encounter different non-playable characters who need assistance from Bayek. These side missions, which typically involve rescuing prisoners, defeating enemies, collecting items or investigating items of interest,[6] often take Bayek to locations of interest, where the player can find treasures.[7] Throughout the game, players can explore tombs and pyramids, raid bandit hideouts, solve riddle puzzles to find rare loot, and discover synchronization points, which then unlock additional locations of interest and serve as fast travel points.[8][9] Other side activities players can undertake include competing in a gladiatorial arena where the player fights waves of increasingly difficult combinations of enemies culminating in a boss fight,[10] participating in chariot racing,[11] and solving stone circle puzzles.[12]
