Overview

More than 100 (!) builds of S.T.A.L.K.E.R. and its add-ons have been leaked over the years. These includes diverse alphas, pre-betas, betas, E3 demos, special presentations and even SDKs. More details are provided for selected builds.

The build numbers are thereby not always unique; due to a quirk in the algorithm numbers are given not at all or multiple times, but each with a different date. Decisive is always the compilation date, of which the build number can be calculated as follows:

days = [0, 0, 0, 0, 0, 0, 0, 31, 62, 92, 123, 153];
build = 365 * (year - 1999) + days[month - 1] + day;

Who would like to, can paradigmatic calculate possible build numbers for oneself:

In April 2007 the algorithm was adjusted, so that the build numbers are now unique and impossible ranges can no longer occur.

S.T.A.L.K.E.R. Alpha 2

• It is rumored that another alpha from 2003 is existing. This one was supposed to be available only at one website (not inside any network) and one could buy it there for $20.
• This fake had found its way into the eDonkey network:
  ed2k://|file|stalker_alpha2_by_yoghourt2004.rar|123803622|BC61BBA7BBA2F0795B917ADEB46EF297|/
• The password is "pcf2004" and the file is approx. 118 MB in size.
• It is probably the newest trailer from back then.

S.T.A.L.K.E.R. Alpha (Build 1154)

• Download by BitTorrent: tstracker.ath.cx
• The alpha is from 08/28/2002 and 320 MB in size. It contains this time two big maps, which are completely traversable including buildings and use of ladders. One vehicle, the Niva, is also featured as well as soldiers and zombies with AI. A new weapon, binoculars and flying crows are also new. Furthermore there are working light and shadow effects.
• You probably need the tool 3D Analyze to emulate "HW TnL caps".

S.T.A.L.K.E.R. "Dream" (Build 1935)

• It is not really a true leak since GSC themselves offically uploaded on 02/25/2009 this then five years old build to their server offering it as a download.
• There are 14 parts à 95.3 MB resulting in 1.27 GB and unzipped a fully 3 GB in size. The build 1935 is dated 10/16/2004.
• Contained are the following 17 maps:
  • l04_darkdolina
  • l06_yantar
  • l05_bar_rostok
  • l02_garbage
  • l04u_darklab
  • l03_agroprom
  • l10u_radar_bunker
  • l12_stancia
  • l13u_warlab
  • l09_swamp
  • l01_escape
  • l07_military
  • l10u_secret_lab
  • l12u_sarcofag
  • l10_radar
  • l13_generators
  • l08_deadcity
• Even a level editor is included.
• Download from GSC server or from a mirror!

S.T.A.L.K.E.R. Beta (Build 2215)

• Download by BitTorrent: tracker2.dyn.pl
• With three years of development time apart from the alphas is the beta from 04/25/2005.
• It has four (multiplayer) maps:
  • mp_exp_bath
  • testers_mp_factory
  • testers_mp_pool
  • testers_mp_railroad
• To this there are three modes:
  • Deathmatch
  • Team Deathmatch
  • Artifact Hunt
• The physics is completely integrated, working respawns, weapons purchase menu and even anomalies!
• Instead of batch files there is for the first time a real server browser.
• All in all it gives a much more stable, mature and completed impression compared to the alpha predecessors and this seems to have an effect on the filesize: It is about double in size having unzipped 416 MB (zipped: 248 MB).

S.T.A.L.K.E.R.: Clear Sky E3 Demo (Build 3120)

• The S.T.A.L.K.E.R. prequel "Clear Sky" is also having the honor and presents itself as E3 demo from 08/19/2007.
• It is 491 MB in size.
