Batman - Return to Arkham Asylum (Part 6)

Joker and Scarecrow in one level seems like overkill. I mean Joker you hear and see throughout the entire game anyways, but then you add in the psychotic doctor aka Scarecrow into the mix and its a whole different ball of wax. Especially since the dude looks like a malnourished vegan on his way to protest a beef plant. Each part of this game though is still amazingly good, even if you do have to deal with hallucinations on the way through it.
