Looks like an fascinating game, uses the Silent Storm engine, one of the most beautiful game engines I've ever seen.
From what I've read so far, H&S is an amazing game with an incredible level of freedom to it, though unfortunately very unforgiving and due to the nature of the project (started as a mod and originally written in Russian), still riddled with some bugs and various issues, though a lot of these have supposedly been patched now.
I haven't picked a copy of it up yet myself, because I simply don't have the time for games I once did, let alone the spare cash. There's only a couple-three message boards out there for the game (in English, anyway) and they're dead slow, so finding info on the game is like finding a needle in a haystack.
Anyone here played it? I'd be interested to hear your thoughts if you have.
