PC version is out on steam.
Just played through it. It's gory and fun. The graphics are stylized cell shading, no eye opener but still good.
However I'm on the fence about buying it.
Most of the demo I did all my kills by doing a grab and then a finish move to achieve 30 points(standard kill is only 10+5 points)these points are used to upgrade your skills/powers.
I'm afraid that going through the entire game doing this could get tedious.
Personally I'm not a fan of games that take this approach of having to kill my enemies a certain way to achieve maximum points.
