This is a highly missable achievement as certain enemy spawns do not repeat later on (Deviant Kantus especially) and if missed can force you to have to do another playthrough of Jacked mode so use the following as a reference to hijack the enemies as and when you encounter a new enemy.
You have to invest skill points for Jack all into the bottom left skill tree from the very beginning to be able to unlock the Hijack skill ASAP when you reach level 4 (my personal recommendation is to choose the Toxic capsule over Sonic capsule lvl 2 early on). You should have the Hijack skill unlocked when you are about to play Act 2 Chapter 4 (main mission).
Below is the likely order in which you will hijack all 15 non-boss enemy types as you progress through the campaign..
Act 2 Chapter 4 - Wretch, Hammerburst Drone, Ticker, Kantus
Act 2 Chapter 5 - Theron Guard, Sniper Drone
Act 2 Chapter 6 - Disciple
Act 2 Chapter 7 - Boomer, Deviant Kantus
Act 2 Chapter 8 (side missions/Corpser boss fight) - Grenadier
Act 3 Chapter 1 - Deviant Disciple
Act 3 Chapter 2 (side missions) or Act 3 Chapter 6 (side missions) - Deviant Wretch, Deviant Hammerburst Drone
Act 3 Chapter 3 - Zealot, Deviant Sniper Drone
If you have diligently hijacked all enemies you should definitely have the achievement unlocked by the time you reach the Act 3 Chapter 6 main mission if not earlier. Good luck !!!
