Another scenario by the creator of Luna West. This one has some pretty serious bugs... I almost didn't put it up, but I figured if enough folks emailed the author, they might get fixed. Worth a look, anyway... Non-linear.
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).
