Two maps, sharing a texture installer (compatible with the other MC products, Canyonlands and Bobco, available here as well). The Madd Ox building is the author's work building, and it's really well done (love the 70's carpeting!). Hijacker is a solo map (3 levels) in which you play DB Cooper. The plane is great, and the final level uses Buskey's Master Wall very nicely. (This level is repeated, tweaked for net play.) Very, very classy.
