Anomaly is a standalone S.T.A.L.K.E.R. mod powered by an x64 version of the X-Ray engine. Starting with version 1.5.0 Anomaly uses a custom engine build called the XRay-Monolith engine. After almost one year of development of the Anomaly 1.5.0 update, the mod continues its way on expanding and adding new features while maintaining a high level of quality and replay value.
Lets you squeeze through around NPCs, your body will move around an NPC but the camera is still pretty wonky when you do it. Side effects might include weird ladders and being able to go through tiny holes. Works with Anomaly 1.5 b3 update 3
