I have kinked out most of the stuff, especially the missing elevator button in Outpost 21. It will not take a long time to add quests and fix some of the quest greetings. But after I have done that and I am confident that I have done all that I could, then I will release the final version. I am not rushing this DLC as I did with the "Ballad of the Missing Marat". I will also make a credits video, crediting Clone Gaming Studios by username and also Ryan Main (the excellent composer for the mod) and myself (for making Desert Region 2).
You won't have to wait too long for the final DLC to be released. It may be released in Q1 2010 as planned, but it is only an estimate.
