Works on mine - Win7x64 Home Premium. There's a bit of a sound issue, with a little intermittent distortion & echo, but nothing that makes it hard to play.

Thanks Wulfc for your help I am going to buy it now that its cheap =]

Ok I just bought the game and it works like a dream!
What a great game so far, it looks and feels like incubation which I am really happy about!

Yeah, it's very similiar to "Incubation" and I meant it as a compliment.
One of my all-time favourites, very hard and almoust impossible to finish without thinking about what you're doing. On the other hand, if you discover secret stash of equipment and learn how to use flamer/paralyser combo effectively - it becames almoust too easy.

Just word of advice - conserve the ammo and don't switch weapons between characters (they gain levels as they're using them, allowing for much more damage and accuracy).
Also - close combat weapons ALWAYS hit, so using bayonete to finish off an enemy is actualy very good idea.

Thanks for the tips and did you play The Wilderness missions for incubation? they are much harder!

Actually, I'm planning to purchase whole Titanium edition from GoG. I only own original Incubation right now.
Thanks for info.
