Marowski will not die!

I'm currently trying to complete the "Kill Marowski" quest and it's infuriating!

I have the level 3 Sandman perk. I've tried every type of weapon. As soon as he's asleep, I sneak into his room and try to V.A.T.S. his butt. Every time his health hits 0, he sits down for a few seconds (during which time the residents have turned hostile), and then stands back up with full health.

Anyone know what's going on? Is it a glitch? Am I doing it wrong?


Probably a Glitch

The sitting down and then regaining all his health means the game has him marked as an essential (i.e. immortal) NPC.

Letting him reset may help:

  1. Leave the area he is in (preferably to somewhere far away)
  2. Wait for ~20 days in-game time
  3. The area should have reset

Otherwise, if you're on PC there are probably console commands that could help (either make him not essential, or simply force the quest to advance), but I don't have the info for those off the top of my head.

(Note: I've not played this mission myself, I'm basing all this off of my experience with Fallout 4 and the other Bethesda RPGs)
