Xenosaga Episode III: Also sprach Zarathustra is a role-playing video game developed by Monolith Soft and published by Namco Bandai Games for the PlayStation 2 in 2006. It is the final entry in both the Xenosaga trilogy and the larger Xenosaga series, which forms part of the Xeno franchise. Concluding the narrative of Xenosaga Episode I and Episode II, Episode III sees Shion Uzuki and the battle android KOS-MOS search out the origins of the hostile alien Gnosis while being hunted by Shion's former employers and four powerful humans called the Testaments. Gameplay is carried over from the first two games, featuring exploration of environments through a linear narrative, while battles follow a turn-based system featuring multiple leveling systems and combat with both a human party and mecha.

Concept work for Xenosaga Episode III began during the later development of Xenosaga Episode II in 2004. The development team's aim was to address issues raised by fans and staff with the previous two Xenosaga games, along with bringing the story to a satisfactory conclusion. Due to the decision to turn the intended six-part series into a trilogy, the original draft for Episode III was substantially reworked. As with previous Xenosaga titles, the subtitle was drawn from the work of German philosopher Friedrich Nietzsche.

Upon release, the game was praised by critics, and went on to sell over 340,000 copies worldwide. The mixed response to the Xenosaga series left Monolith Soft staff in a state of low morale, partially leading to the development of Xenoblade Chronicles.

Gameplay

Xenosaga Episode III is a role-playing video game where players take control of a party of characters; during the game they explore a variety of environments from towns and cities to dungeons. During the course of the game, a Database is filled out which holds entries on terminology, characters, story events and earlier events from past Xenosaga games. The game features a variety of quests including the main narrative and side quests accepted from non-playable characters. The party can purchase items and equipment from shops found in friendly environments throughout the game. Gameplay segments are separated by story sequences, which are told through both traditional full-motion cutscenes and segments with voiced text boxes within the game environments. Enemies such as monsters can be seen in environments, to be avoided or engaged as wished; the party can also place traps which temporarily immobilize an enemy unit. When the party makes contact with a monster, the battle is initiated. Triggering a battle with a trapped enemy grants a boost in battle. Combat is split into two types; one with the human party members, and one using combat mechs dubbed E.S. units.

When battle begins, the player and enemy parties fight in a dedicated combat arena. The combat is governed by a turn-based battle system. The player party is restricted to three members, but at the cost of one turn an active character can be switched out for a reserve character. Each character has a certain number of health points (HP) and Ether points (EP). If all HP is depleted, a character is defeated. Turn order is governed by a character's "Agility" statistic. Each character can take a variety of actions, ranging from attacking, performing special attacks called "Arts" and using Ether abilities that each consume EP, using items, taking defensive positions that reduce damage, and escaping the battle. Both the player party and enemies have Break gauges, which fill up when either side successfully lands an attack. When the gauge fills, that character is stunned and cannot act for two turns, in addition becoming more vulnerable to a high-damage Critical attack. The Break gauge can be reduced by using Ether abilities, which can also be used along with items to recover HP.

Each player character has a "Boost" gauge that builds up during battle, which can be used to either perform two actions in a single turn, or deliver character-specific special attacks. If an enemy is killed with a special attack—an action labelled "Finish Strike"—at the end of a battle, they are granted a boost to their experience points (EXP), in-game money and skill points (SP) used to upgrade abilities. EXP raises a character's health and basic statistics. SP are invested in skill trees for each character, with each tree having a different emphasis in its skills to unlock; some trees include powerful Ether attacks, others Break damage, and others defensive or supportive abilities.
