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.
Texture says 100 instead of 200 since the gun holds 100 and that's apparently more realistic than making it hold 200.
Very cool.
I don't even know M60 exists in Anomaly.
