This is quickly becoming one of my favorite stages. It opens up with a fight on an elevator. As any old school gamer knows, nearly EVERY beat em up must have at least 1 stage with an elevator fight.
(It's like a rule or something.)
Also if you take a certain route, and open up a certain chest you will fight a clone of yourself. Not an exact clone mind you, but your class character with your weapon type...at max level. Needless to say I busted his ass down quick. :D
EDIT:Correction, he's not a clone. A monk will appear regardless.
And then there's the boss fight:
[Omega's witty observation about the boss]
You know for a witch she certainly lacks the happy go lucky personality the mage has. No flying a broom, no "WOOOOOOOOOOOOOO", no machines exploding. Feels good man.
