visitor (Boss A -Round 1-) [Metal Black Arcade rip] 

if this track doesn't send shivers of pure, unrelented fear & anxiety up & down your spine... there's something horribly wrong with your senses! THIS is what a boss theme should be about: letting you know you're about to meet hell face-to-face and it's either fight or die! the whole Metal Black OST is without a doubt (at least IMO) Team Zuntata's musical magnum-opus!

I have been trying to complete the Space Invaders Infinity Gene soundtrack (DLC tracks and PS3 tracks included) for almost 2 years! After searching iTunes and comparing with the music while the game is playing, I have finally completed it, thanks to you! Also love this track to death.

They really made the best soundtrack ever🎉

I played this when fighting the Hydra at Hulao Gate in Warriors Orochi 3.
