The stand-alone mod S.T.A.L.K.E.R. Anomaly aims to be the most stable and customizable experience for fans of the S.T.A.L.K.E.R. games. It's powered by the Monolith 64-bit engine, a custom fork of the X-Ray engine.
This is the download for S.T.A.L.K.E.R. Anomaly 1.5.1 - the final version of the 1.5.x update series. Do NOT install this on top of older 1.5.0 versions, use a new, empty directory instead.
