Pros:

No More Heroes Music
Jet Set Radio Style
Lots of crazy lighting rooms
Lots of colors
Signs and rooms with animations (gifs)
Iinspired in a future Tokio (That's Jet Set Radio about)

Cons:

It's still beta :(
The ammunition,weapons etc they  are too bad spreaded trough the map.
Sky with texture problem.

Conclusion:

I really like this map,finally something new and fresh for L4d2.With a few fixes this map is going to be awsome,can't wait to play it properly.
Keep it up with the good work!!! i give a 60!
