Achieve a score of 150,000 points on Lone Wolf.
How to Get One Final Firefight Achievement
This will also unlock the achievement, Left Behind.
Start the mission Lone Wolf on a difficulty you feel comfortable surviving on. Easy is recommended, and Normal is also suitable. Activate the skulls you are comfortable playing with. All are advisable for reaching 150,000 points. Make sure scoring is on.
The strategy is to flank the Elites and assassinate them. With the Black Eye Skull on, this is how you will regenerate shielding. Grunts can easily be killed with their Plasma Pistols.
It may take around 10 minutes to get this achievement depending on skill and multipliers like difficulty and skulls, but it’s not challenging.
