This is a great little product for a one-shot scenario, or a drop-in for a campaign. It's aimed at beginner-level parties, but has alternative setups for more advanced parties, up to Rune level.
Without spoilers: what we have here is a cave-based mini-dungeon, with Trolls as foes. Expect tricksy shenanigans from the Trolls when (not if) the party goes on the warpath. It's the GM's job to get them on the warpath, of course, and quite a few ideas and hooks are presented. As well as maps for the GM, there are player handout maps too, should you want to use them. The PDF even includes printable miniatures for the Trolls and Trollkin. Usual story: fold, glue to a penny and you're all set.
Non-map graphics for me are less important than GMing details, but the imagery here is pretty nice, giving not just the Trolls but Trollkin individual personalities.
I haven't yet run my players through this, but I'm expecting to give it a try in the next couple of weeks. Fun will, I suspect, ensue.
