i just played a game...
but...
it was almost completely silent. i couldn't hear the enemies, only the sound of my gun firing when i pressed a button.
quiet ambiance outside in the "hub."
and the enemies...
entire cut-off limbs with no bodies in sight.
creatures with tall, stretched out mouths which were always open.
large flies.
ribcage-shaped fleshy monsters which would crawl around and spit balls of flesh at me.
no music.
a single NPC which just stood still.
large skulls on a large wall in the "hub."
