A 17-level scenario (or a little more, if you count repeated levels), with modified shapes and art. (The shape mods are mostly a new weapon, but there are a bunch of small things that add up to a more complete experience... check out the doors, for instance.) It could use a little texture alignment, but overall quality is quite good. (The first level is very slow-don't judge the entire scenario by it.) Nice AI evolution.

Mark Conahan has taken all of his M1 maps (including those originally in Canyonlands, Go Wif Jeza, Bobco, some single-map releases, and some previously unreleased maps), tied them all together with a cynically entertaining storyline (reminded me of Harry Harrison), and bundled them with a huge assortment of shapes. These include all those first released with the above maps, plus new scenery, and some shapes and physics created by other people (the battle mech from Dogs of Pfhor, the fusion and spanker bobs from Dave Turner's High and Low map, a sight patch...).

Actually, 7... with outrageous accents. Mostly geometrical (big squares, or long hallways leading to other long hallways). If you can avoid the fisheyes, The Hard Machine is quite fun.

You're in platform hell, and you don't get to leave until you kill everything. Or die.
