Ship placement, basic scripting, and arrival cues are done. I'll do a preliminary balance check later on this evening. After that, it's onto dialogue, briefings, and finalized scripting. I'd say another two days to beta, followed by a week of me getting ever more fed up with the mission, as I root out the bugs. I probably won't have time to make a second submission, unless the first one is exceptionally easy to debug.
Though somewhat off-topic, I'm wondering if HLP has any plans in the works to set up a replacement for the now-derelict Volition Watch mission archive. It would be nice to have a centralized place to submit missions again, and the staff and member reviews were always quite valuable when it came to revising campaigns and stand-alone missions.
