The mod itself works, but there is a compatibility issue. The old classic axis works fine with the swimming script (swim.cs), but the new one cuts off the ability to turn in the water... I.e. once in the water, the character swims only in a straight line (neither the mouse nor the buttons can be turned).
You take out a weapon in the cut-scene - the cops get angry .. The scene ends - and you are already dead ...
Does anyone know if this can be fixed somehow? )
You can try to patch 4Gb Patch (another program, but the essence is the same)
