Different ambient/sound-effect tracks. MTVMG2
nice effects. 4 is quite scary and my favourite is 2 actually
Surrounded - Whoa holy crap that's like very evil-ish like a demon is breathing on you as you fight the minions he is about to send to attack you.
Monsters 6 - Here too very dark, very spooky, and they sound like they may have gas. Maybe these monsters ate at McDonalds before this fight scene.
Monsters 2 - Okay these ones are less constipated, very really mean sounding. Very demonic and flat out scary man.
Monsters 5 - Definite dungeon scene.... A poorly lit stairwell illuminate this giant beast.
Perverted Monsters - Nice monsters watching porn... Monsters gotta get some lovin' too.
