In the past, mods required the user to own a copy of the original game to extract the necessary assets (textures, sounds, models). Anomaly is unique because it bundles everything needed to run.

The legality of S.T.A.L.K.E.R.: Anomaly rests on a combination of historical permissiveness from the developer, the use of open-source engines, and the "fair use" principles surrounding non-commercial fan works.
