Quick review of the softcover. Fun scenario, well laid out with a lot of great art, maps and handouts. The added environmental rules are great and can easily be ported to any other scenario (homebrew or otherwise) that takes place in an extreme cold environment. That aside, I do have a couple of nitpicks.
1) The book could have used another pass at proofreading. There are a number of typos and random odd characters here and there, a few in the middle of the boxed text the keeper reads out to the players. All easy to work around however.
2) There are a number of NPCs included that can be used as pregenerated characters, which is a great thing, but the stats are a small box that is a little odd to print out and use at the table. It would be great if they were full size character sheets. (Just a personal preference.)
Again, these are minor nitpicks, this is an overall fun scenario, it took my table about 12 hours to run and they had a blast.
