New to Stalker

Yo all Fairly new Stalker here. I’ve watch and enjoyed a lot of Stalker content over the last few years and Stalker 2 is the first game of the franchise I’ve played. So far, I fecking love it.

I’m current stuck on some psycho-mantis-midget giving me grief in a tunnel and I can’t seem to to kill the lil’ cunt no matter what I try. Any tips?

Much love, Another Zone causality
