A new version 1.1 for the second mission is uploaded. It has some major changes in scripting. Make sure you use this, please. The mission has some complex scripting and major randomizations, as far as I can see it and tested it, all chains of events and conditions work well now.
Note that the mission plays for 1-3 hours, depending on your way to approach the objective. I also would think that it is pretty mean and tough going. The many small needles easily can accumulate to one lethal nail.
