What do you think is the #1 monster in the Frictional Games Penumbra & Amnesia?

[The Rock Worm]

I believe that the thingie the Infected have is actually an umbilical cord...

When I first encountered the Gray Rock Worm I knew I wouldn't want to meet a wild one, but would be cool if they really did live deep underground.

There are lots of scary worms in the world, thankfully none of them are as large as in Penumbra! Check out the Bobbit Worm.

I've heard about the Bobbit Worm, he's the first predatory worm I heard about. Here's a video of it and a small fish (video not mine, found on Youtube) http://www.youtube.com/watch?v=tkUSx6aQGXU ...and below is a video of a land-based predatory worm (a Leech actually, but instead of sucking blood like its relatives, it hunts other worms and bugs! This video is also not mine but found on Youtube)
