Oh man this game is hella fun. Really great hack and slash action. It's sorta like... Max Payne but instead of guns you've got adamantium claws. Every once in a while you'll pull off a crazy move like slicing a guy's torso in half or whatnot and it'll go into slow mo while the blood splatters everywhere. Never fails to make me laugh. And it's all optimized really well for a PC port. This was made by Raven, so that's to be expected, those guys have been working on PC games for ages. It's just so cool seeing yourself heal back up from getting blown up, with skin growing over exposed ribs and muscle.
The only problem I've noticed so far involves the platforming. It's not really done well, and this one section in particular is super frustrating because you can't quicksave. Games like Assassin's Creed and Prince of Persia really show how bad and outdated this platforming is. But most of the game isn't platforming, it's usually killing soldiers in really brutal ways with your claws. My favorite move is leap, it's a really fast lock-on ability that you can perform from 3 to 40 feet. Just lock on a guy, leap and knock him over, jump up and dive down on him again to kill him, then leap onto the next guy, and rinse and repeat. You can do this to wipe out entire squads at a time. That never gets old.
