When I bought this supplement I wasen't expecting much and dreading alot. I was overly suprised by the classes and the actual M.A inside. It is not some cheap movie spin off but well thought out Martial Arts (M.A.). I was hoping and will probably have to use the SpyCraft rules for "GunFu". I use DW1 and 2 for the basis of a RPG based on James Axlers "Deathlands" and all of the DW material fits nicely.
