Just want to say, I serendipitously found this mission on Christmas and played it all the way through, and completed all optional objectives as well. I'll admit, I had to search online for where the hell the final piece to the snowman was (the hat! I figured but had no clue where it was).
What an excellent, well done mission. I really enjoyed this one. Many details were considered that surprised me.
Again, well done, and thank you.
