A bunch of staircases out in the open. Good for killing folks who haven't mastered the art of looking up or down.

A big, rambling level. Plays pretty well as a solo level, too.

An interesting shapes editor that allows editing of the shapes from within the program.

No relation to Encounter:Colony. This started as a compilation of levels, but grew to its current form. Some pfhor were taken for study, but got free, and don't realize they lost the war. You've got to protect the research facility. Comes with everything needed (shapes patches, maps, physics model, sounds patch).

A cityscape, with ray-traced graphics. Cars and helicopters on the outside, gun-toting secretaries and businessmen on the inside. Nasty! It's your job to find the big boss upstairs.

The beginnings of an Aliens package. New shapes (they still need work), and a physics model and map round out the package. Really designed for net play.
