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.
Adds brand new skyboxes to Anomaly! Uses skyboxes from Atmosfear, AREA, Dead Air, SWTC and Dead Air Extended Graphics! UPDATE: Removed unused files!
This mod was basically just me taking the best skyboxes I could find and mixing them all together. Really big thanks to Atmosfear, AREA, Dead Air, SWTC and Dead Air Extended Graphics!
