Upon arriving, you feel something..... you're unsure, but it feels like somebody's watching you. Your every move. Dark and cold tunnels lead downward for who knows how long.

And every once a while, you would hear a clicking noise, a growl, or screech.

Whatever's down here, it wants to kill you, or eat you.

(WARNING! WARNING! LEVEL 5 THREAT DETECTED!)

(^ which means that you HAVE to have 5 people with you at all times)
