You should not die, go MIA or extract with a runthrough while this quest is active
How to complete the quest?
You need to kill all bosses without dying.
Quest is very hard, it is recommended to play in squad. Goons can be killed by anyone, but Boss must be killed by the person with this quest.
As guards and bosses all have good ammo, it is recommended to take high-tier armor, such as Altyn, Slick, Hexgrid. Also, your ammo should be able to penetrate 5+ armor class: BS, Igolnik, M61, M995, SNB
The hardest bosses are: Glukhar because he has the biggest group of guards, and Killa because many players with “The stylish one” quest want to kill him, and the boss himself is dangerous with his aggressive AI and great equipment.
To refresh your memory (Spawn, etc.), there are quests to kill each boss below.
