In The First Samurai, the protagonist undertakes a quest as the first samurai in the history of feudal Japan, and must compete against rival swordsmen. Eating food and drinking sake will help the player get stronger, while fire and enemy contact will weaken the samurai. The main objective in a level is to collect a set of four items which must be used to get access to the area with the end of level boss. Magic pots serve as checkpoints and are activated with the energy of the player’s sword.
Killing a monster releases a portion of sword energy which the player then collects automatically. Using a bell at the right place removes an obstacle blocking the player’s path. The player starts out as a hermit in an ancient forest, but he eventually becomes powerful enough to fight in the villages and towns, and eventually the dungeons.
