This game is a huge disappointment.
12 years we waited for a conclusion to Kate Walker's story that started out as one of the most memorable experiences I've had in gaming and what we get is a let down on all fronts.
The series has shifted it's focus from the journey of self discovery and wonder, to being an errand girl for a group of chubby Eskimo's that at one point are actually called yokels.
Gone is the focus on wonderful automatons, gone is the sublime musical score, the voice acting is terrible, the characters that serve as the main antagonists have no clear purpose, the game is full of bugs, the camera is a constant struggle, the movement controls are awful, the inventory system is backwards, and there's pathing issues everywhere. Oh, and the lip sync only actually sincs up if you play the game with French voice acting.

To add insult to injury, this game does not connect to the previous installments at all. There's a gap from where you left off in Syberia 2 that is never explained, it retcons every established bit of lore, and the game ends on a cliffhanger that can only take the story further away from what made the first game so special. So there's still no conclusion to this story.
And to top it all off, this game somehow manages to look worse than how it's predecessors did. I ran this at 60 fps on the highest settings, which isn't saying much because this game isn't optimized at all, and it looks ugly as hell.

I can find nothing redeeming in this game and $30 is a waste of time and money.
Get the original 2 games, they're $15 in total, and you'll get an infinitely better experience out of it.
This has tarnished my memory of those games and I wish I could erase it from my mind.
Don't. Buy. This.
