How to Start the Bottoms Up Affinity Mission
In Xenoblade Chronicles X: Definitive Edition, affinity and main story missions are unique in that you can only undertake one at a time. If you begin an affinity mission, you won’t be able to start a main story mission, and vice versa. Furthermore, you can only have one affinity or story mission active at any given time.

The Bottoms Up affinity mission in Xenoblade Chronicles X: Definitive Edition becomes available after completing Chapter 4. The mission can be found in NLA’s Industrial District. The recommended level for this mission is 21 and the required level is 19. To begin this mission, you must accept it at nighttime. The primary destination is Sylvalum.
