Lost Alpha Wiki

The Zone Files is a collection of articles that describe the scene of S.T.A.L.K.E.R.: Lost Alpha.

We try to carry out comprehensive studies of the Zone. Our specialists and laboratory technicians are not only working in dusty laboratory facilities, but also carry out field researches. Some of the exposures cannot be registered in laboratory conditions, some "material" is simply unavailable. It happens that the response from the test subjects and from yourself can be noted outside only.

Quoting the guidelines, the principle aim of this wiki "is to document the game in order to build a comprehensive reference base that will assist players cross reference various aspects and nuances that are found during their experience in the Zone. This also would include information of an arcane nature buried in the game files".

A good introduction to the game in general is S.T.A.L.K.E.R.: Lost Alpha, giving a brief overview. The articles about levels, factions, anomalies, armour and weapons and others are the reference base.

The information of an arcane nature, dug out by investigative fellow Stalkers from the depth of the game files, is also documented in this wiki. Sometimes the articles are hard to find, as they don't fit the reference-base-type structure. This article is intended to collect references to this valuable information and give open-minded Stalkers the chance to get a deeper insight into S.T.A.L.K.E.R.: Lost Alpha.
