Awesome Hydrolyst Sound

[BladeRambler]

Hi DE audio engineers, just want to say thank you for all the Eidolon sounds, but one in particular is crazy awesome. When the Hydrolyst winds up before its massive ground smash, there's a good 2-3 seconds of creaking/cracking noise, much like an old wooden battleship. When it does that move, it's usually eerily quiet and all you hear is that sound. It's amazing, it sounds so ominous and cool that I lose focus even after a hundred battles with it. How did you make that and what did you pattern it after?
