How to unlock the Special Operation Task Squad achievement in The First Descendant - Definitive Guide
As noted in What Was Always Expected (40G) this is one of the most popular activities in the game. Wave 7 is really no challenge, especially with people aiming to get Level 40 characters here often. The achievement unlock as soon as you complete Wave 7, so even if you continue on and fail at any point, it's no worry. You will find this in the X zone of Kingston, on the X side of the map.
