Scaling the sound levels of wind or rain based on speed/severity my be beyond the scope of the current sound engine, but would make the game much more immersive and provide an element of gameplay not normally experienced in other games.. Imagine trying to hear your squad leader shout orders on a calm day. You hear him very clearly. Now, imagine trying to hear him in a thunderstorm with high winds and heavy rain. Currently, you hear him the same as on a calm day. What about vehicles? Did you hear that OPFOR vehicle roll past your position at about 100 meters? Of course you did! BUT, would you hear it during a heavy rain, or thunderstorm?
