Scarecrow

I've never played Arkham Asylum (I know, bad nerd) but I've seen plenty of images and footage from the game and it looks amazing. The characters design and art direction have inspired many very cool MOCs, like this Scarecrow from Julius No, scary cool.

Arkham Asylum

This is epic.  Xenomurphy has built an amazing version of everyone's favorite (and easiest to escape) prison for the criminally insane, Arkham Asylum. And as if this MOC wasn't amazing on it's own, there's an entire 82 page book of the making of it in his photostream, and it's free. Go there, now.
