what is the scariest monster in all of gaming?

[Ace of Spades]

The THINGS that stalked the halls of Shalebridge Cradle in Thief 3.

 

[Susano]

the tall man

every one who gets it is awesome

That fucker can go crawl back to his "father" and die.

Hate that guy.

Are you kidding? The Tall Man was astoundingly, well, I don't know. He wasn't scary very many times but I still thought he was awesome. Especially in Notes.
Hell I loved that whole mythos.
