imagine long twisting tunnels covered in dense web, obscuring your vision.. so you take out your sword and chop it down, all the while you see dozens of tiny spiders crawling up and along the walls. In 3rd person you see them crawling harmlessly across your shoulders.
you carry on and all of a sudden the ground beneath you breaks and you fall down into a giant web filled chasm, you are trapped and have to cut your way out, but a giant spider comes creeping towards you, its paralysing fangs at the ready.
Yeah I really hope they get spiders right in the game. 1000 small spiders a more freakier than one big one.
