Travel far outside of New Los Angeles.
Xenoblade Chronicles X was further detailed during today's Nintendo Direct.
Using "New Los Angeles" as a home base, your character, an explorer, sets out on the strange planet to partake in missions. They include hunting various creatures and doing favors for other characters. The story is about a society of people who crash landed a huge spaceship onto the planet in the game.
If you don't always want to be in combat, there is also an exploration mode where you can't get hurt. There is no official release date other than Spring 2015 for Japan, and sometime in 2015 for North America
