The death itself

Noah is concerned about attacks on stalkers in Jupiter. Seven invisible deathclaws have been roaming the area and he needs Marked One's help to destroy them before any more lives are claimed.
== Walkthrough ==
To help locate the deathclaws, Noah hands you the Modified Needlegun with custom needles outfitted with tracking devices. The quest requires you to mark at least one invisible deathclaw with them to demonstrate the mechanic - the mutant will be marked on your map/minimap and will be easy to locate after hitting a shot.
There will be seven invisible deathclaws scattered throughout the map, with approximate locations marked below as they can roam a bit. Most are relatively easy to find through sound cues and computerized targeting, but one is in the tunnels below the ventilation complex. Take each one out with whatever methods you prefer and return to Noah to hand in the needlegun. He'll tell you that Nazar wants to speak with you.
== Notes ==
* As usual, a crowbar, flamethrower, or 6 gauge shotgun are all economical ways to take down deathclaws.
* At the start and the end of this quest, additional stalkers that participated in the wave leave the game.
* Invisible deathclaws in this quest do not show up on the Universal Bioradar.
