New demonstration GDC 2003 build with lots of interesting locations, monsters and prototypes of anomalyes. It’s worth saying about features, you can find interesting inventory conception with 3d models(three-dimensional objects in an inventory), fully working cars(presence of hands at driving) + funny ragdoll which was not fully setted correctly.

Dead city – is the legendary location which was created on the prototype of Pripyat. Best known sights are dwelling quarter, Central Square with Lenin monument and city Council building.
Generators – is the locked opening level of old conception. There was military laboratory underground.
Military – consists of abandoned military base with a ramshackle sat down and swamp. Also it’s a ”Freedom” base.
NPP catacombs – is underground building of NPP which player must pass through, to reach Monolith.
Two test levels, demonstrating physics of stalkers and cars.

Who released this build? Where did it come from?

Long story...

MilkywayM16, do you have an easier question? It was released by an extremely mysterious person called <God>. Everything we know about him is that he showes up from time to time, says that our community sucks and throws another new build to the public. He is somehow related to the devs - he is one of them or just some tester. I don't really remember.

Maybe worth to tell... I wondered about it too.

Wow that is extremely amazing and awesome.
