How to Start the Spy Games 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 Spy Games affinity mission in Xenoblade Chronicles X: Definitive Edition can be found in NLA’s Administrative District. The recommended level for this mission is 30 and the required level is 28. To begin this mission, you must complete Chapter 7. The primary destination is Oblivia. Nagi is a restricted character.

Spy Games Walkthrough
After accepting the mission, head to the BLADE Barracks and speak with Nagi inside to trigger a cutscene. Once it concludes, speak with him once more. He’ll suggest you approach the fortress from the shore on the east side of it.

To begin infiltrating the enemy stronghold, travel to the objective just south of Jair Fortress on the far eastern side of Oblivia. If you want to take Nagi’s route, head to FN Site 332 and travel northeast. This will bring you to a long hill leading straight up into the enemy’s stronghold. There will be quite a few enemies with levels in the 50s, so make sure to avoid them. The building we need to infiltrate will be the first one you come across along the hill.

Enter the facility to trigger a cutscene leading to a fight against a couple of level 30 Marnucks. Take care of them to finish retrieving the data. You can then travel back to NLA and head to the BLADE Tower. Going inside will trigger another cutscene.
When it concludes, go to the Ma-non ship on the Starboard side. You’ll want to speak with Pfeffen there to enlist their aid to decrypt the Ganglion’s files. Once he agrees to help, return to the BLADE Tower for one last cutscene. The mission will then be completed when it ends.
