Half Life Refrences in S.T.A.L.K.E.R.: Shadow of Chernobyl

[Makarov]

So apparently after the events of Half Life, Gordon Freemen decided to head over to
Chernobyl. Here is some evidence to the point.

Gordon's body:


Quote from PDA found on said body:

God damn my bosses...won't leave an old man alone. First Mesa, then some strange town in Russia. And now they send poor little Gordon into the endless Ukrainian plains. Take your jemmy and have fun.

Made it into the Zone. Are there really no bears here? Who am I going to fight then? I'm not finding my bearings too well in this place. I had to give my little crowbar away for a can of meat.

The blowout has started. The Barkeep told me to hide my ass and keep it hidden. I chased some rats out of an abandoned tunnel. I hope to wait out the bad weather in here.

He was supposed to be part of a barkeep mission to recover a pistol, the code of which refers to him as "familiar" in reference to the Half Life series.

The mission code:

<string id="barmen_find_item_2">
<text>Find the foreigner's gun.</text>
</string>
<string id="barmen_find_item_2_descr">

An interesting assignment. The name rings a bell...
but where do I know him from?</text>

There once was this foreigner in our neck of the woods...
Gordon was his name? His whole manner gave out an experienced
stalker, but he said he’d never been to the Zone. But anyway,
that’s not the point. He did vanish somewhere in the Zone eventually.
But he had this rather curious thing, the Black Kite. If I could just
take a closer look at it..
