This achievement is for defeating Kai Leng after you attack Cerberus headquarters. It is part of the main quest so you cannot miss it because you need to go there in order to get a certain item. Once you enter the illusive mans room Kai Leng will appear and you just need to beat him in order to get the achievement.
