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.

Desert Levels. Great textures (first water I've seen outside of the M2 preview), and enough baddies that these levels work equally well as solo (explore) levels and net (kill) levels. The patch affects different texture sets than Bob World Headquarters (see above), so they can both be applied to the same Shapes file. This is now Rev 1, with a few textures fixed.
