Does anyone know how to get this swooping sound?

I've tried for weeks on end with no luck.

Any help would be greatly appreciated, as I am not looking to copy the sound in general, but the basics of how to get it so powerful. Thanks guys!

Do you mean the intro growl synth?
It's just a lowpassed osc (choose to your own taste) with a slow LFO opening up to it.

I think I have an exact copy of that laying around here, if you're really curious and can't find it I'll have a look.
