Hi,
Ok, so I'm stuck in Stalker Shadow of Chernobyl. I'm at that monolithian camp with the antennae things and the brain schorcher psi-emition stuff. But I can't for the life of me find the entrance to X-19. I've spent a few hours just walking around, and nothing - no doors, stairways. Can anyone help with the whereabouts?
Thanks!

I beleive you need to follow the railway tracks into a tunnel.
If it's the lab in lake Yantar the entrance should be in a building.

No, I think your thinking of X-18. With that guy who goes 'Hello? Hello?' that you can almost hear from Barkeep. I mean the one in the Red Forest. Thanks for the answer though!

P.S. These page might help if you don't know where I'm talking about:
I'm at the Monolith camp that has these antennae: http://stalker.wikia.com/wiki/Brain_Scorcher
And want to get to here: http://stalker.wikia.com/wiki/Lab_X-19

Oh, right. I'll check it out! Thanks.

Yes, it is, thanks so much! It's just through a train. Jeez, I'm so low on ammo. Anyway, 'good hunting stalker!'
