Xenoblade Chronicles X is an open world action role-playing video game developed by Monolith Soft and published by Nintendo for the Wii U home video game console in 2015. Xenoblade Chronicles X forms part of the Xeno metaseries, being a spiritual successor to Xenoblade Chronicles without any narrative connections to prior Xeno titles. Carrying over several gameplay elements from Xenoblade Chronicles, players explore the open world planet Mira, completing a variety of quests and unlocking new regions to explore and gather resources from across Mira's five continents.

Xenoblade Chronicles X takes place on the uncharted planet Mira. Following Earth's destruction during an alien war, humanity attempts to escape, with only a few ships surviving. One such ship, the colony New Los Angeles (NLA), narrowly escapes and crashes on Mira. After being rescued from a hibernation pod by a woman named Elma, the player character, a customizable Avatar, becomes a member of BLADE, which protects NLA and seeks the Lifehold - vital to their survival - while fending off the hostile Ganglion and investigating Mira's secrets.
