S.T.A.L.K.E.R. build 1935 released for free download

Originally announced in November 2001 for a 2003 release, S.T.A.L.K.E.R.: Shadow of Chernobyl (or S.T.A.L.K.E.R.: Oblivion Lost as it was known then) was renowned for its long development cycle and frequent delays. 

Whilst in development, numerous video clips and hundreds of screenshots were circulated showcasing the game's X-ray graphics engine which featured HDR rendering, parallax and normal mapping, soft shadows, motion blur, widescreen support, weather effects and day/night cycles.

The game was also hailed for its proprietary ALife artificial intelligence engine, whereNPCs would accomplish tasks, combat, rest, feed and sleep. The non-scripted and innovative nature of the characters meant that there were an unlimited number of random quests.


However, when S.T.A.L.K.E.R.: Shadow of Chernobyl was finally released in March 2007, much of what was promised had been cut or changed, such as using vehicles, monsters and many of the role-playing elements.

This version is not so much a demo or mod, but more of an insight into the game's development. Curious fans of S.T.A.L.K.E.R. will find this both fascinating and intriguing although may wonder why some elements were removed from the retail release. 


I cannot guarantee stability, so bugs and crashes will occur. They have also said that they will not provide technical assistance.
