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.

A well-built 5D map that's seriously confusing until you get the hang of it... and then carnage gets absurd. Don't stay on the hill for too long... it's very, very dangerous. Nice use of the portals concept. Update darkens up the outside stairways, and reshapes the portals. Overall, this is a very playable map.

A big cross-and-ring level. Nice fast elevators.

A bunch of small rooms (classrooms, I suppose) leading to a larger (auditorium?) arena. The readme talks about separate map and physics files, but I've merged them... watch the hunter.
