Way of the Samurai 3 is set during the Sengoku Period, where the player takes on the role of a lone samurai. The game follows an authentic setting, with a deep sword-fighting system and cause-and-effect role-playing. The story revolves around Shuzen Fujimori's rule over the region Amana, which he maintains through force to keep control.
The player must decide whether to join the Fujimori Clan, protect the villagers in Takatana who desire peace, or leave Amana altogether, leading to a complete game reset. The game offers freedom to roam eight zones of Amana, with multiple possible endings based on the player's actions and choices throughout.
The gameplay involves three options: listen, apologise/beg, or attack when interacting with people. These actions affect the respect the merchant has for the player, influencing rewards and overall experience. The game features a realistic day and night cycle, NPCs living ordinary lives despite the player's presence, and various mini-games like chopping vegetables.
The player must manage their swords, hammers, and spears, balancing quality and durability levels to perform both offensive and defensive moves. Decisions influence relationships with groups, changing how they interact with the player. The player can choose between killing or using blunt attacks, affecting reputation and future interactions.
Throughout the game, the player will encounter potential partners, some of whom can join them in exchange for money, while others can be "romanced". Partners provide an additional edge in combat, unlocking access to mini-games and side jobs. Romance options allow partners to live with the player, granting access to their home and personal items.
