Kill the Bloodsucker in the Dark Valley is an optional sidemission featured in S.T.A.L.K.E.R.: Shadow of Chernobyl.
Description[]
They say that the troops left the Dark Valley. And then monsters started pouring out of every crevice. The stalkers already spotted a bloodsucker there, and an extraordinary one at that - he's not afraid of open spaces. Any way, once word gets around to the scientists, they'll definately want to study this bloodsucker. And I want to be the person who hands them over the body. Your job is to kill the bloodsucker, and I'll take care of the rest.
― Sidorovich

Completing the mission[]
The Bloodsucker is in the south-easter part of the Valley. It's a big open area and the target is just a single normal Bloodsucker, so you shouldn't have any problems.
