This has to be the most obscure game I have ever come across in terms of information available. The so called manual that comes with the game is very basic. The in game tips give miniscule amounts of information. There is not a single complete walkthrough or let's play on YouTube. There is one Let's Play that is in German, but the person doing it gives up in frustration before he even makes it through the mini initiation campaign. There are no strategy guides, or guides of any kind that I have been able to find after a LOT of searching.

The missions in the game don't even give you the rules or requirements of the mission most of the time. I lost count of how many times I lost a mission that I thought I had won because I lacked vital information such as someone had to stay alive, or only a certain amount of people you were fighting with, or for, could die.

Update:

I managed to finish the game even though there are still a LOT of things I don't understand.

Where did all of the responses go? Since it seems very unlikely that every person who replied came back and deleted their post, it would have to be GOG who deleted the responses, but why?

Let's see if they delete mine. I am having trouble with the game. I cannot hear anyone talk, die, etc..

Could you share some impressions, please?

I promised to myself to try it seriously from time to time but still this game lies almost untouched, though it looks very interesting, at least in "lore" part (its visual and narrative style reminds me of Warhammer universe).

Flagis, I have played this twice now and it is a lot of fun. I can explain a lot of stuff if you want me too. The only thing I think about this game is, is it satanic?

It is a fun game, but I am a little cautious about playing it again because of that.

Satanic, eh? Well, I don't think it is the case here. What exactly made you think like that? There are corrupt religious priests there, yes, pretending to be warriors of light and such, it's quite usual medieval fantasy stuff, really. You may see such priests everywhere then and now, in any religion, in any country, in real life. Is the real life 'satanic'? Some may call it so, the Earth as the domain of Prince of Darkness and stuff but look, it's not the healthy way of looking at reality. Those corrupt priests are born of this way of looking.

So relax, please. Satan has many more important things to do than catching your precious immortal soul by means of a fun PC game, believe me.
