AVOID THIS GAME!!!!
For starters this game uses Quick Time Events which isn't a bad thing, the issue is the the sheer amount of QTE's. Segments that should be cutscene turn out to be a boat load of QTE (quick time event) sequences which if you progress through the game quickly will happen sometimes every 5 minutes or less. Or if you want to you can QTE every single enemy with no sucsse. If you are using a controller the Quick Time Event prompt fades in giving you less time to react where the keyboard prompt is an immediate thing. All around it feels like quick time events were something that was just tacked on at the last moment and it doesn't really fit. But don't despair, the QTE's have a difficulty setting; if you don't want to put up with them you can set it to the lowest setting and watch it as the cutscene it should be although the prompt will still pop up like you are still gonna give it a go.
As for the story you will be completely lost as to what's going on unless you watch the prologue in the extras or on the store page. Gameplay wise it feels like its trying to be 3 different games in 1 and fails horribly.
1. The setting feels like its trying to be the Shinobi reboot for PS2 with the whole modern urban Tokyo ninja thing.
2. Your character looks like Ryu from Ninja Gaiden and tries to be just as cool and fails at it.
3. The combat system feels like it was based around not your first weapon but your second that feels a lot more natural for some reason and happens to be dual wield sword but it makes you use this super slow broad sword through MOST of the game. The upgrade system mimics that of God of War as well as some of the attacks that you unlock via upgrading. The Quick Time Events mimic God of War in the way of being activated in the same ways. Aside from the games it tries to be there are also poorly incorporated turret segments that completely break the flow of the game. There are moments that also happen quite often where you will have to go through your weapons just to continue through the game. And again this wouldn't be and issues if i was done less often but its over used. The gameplay looks and feels very broken as if the cosmetic things where more important the having a solid foundation for the cosmetic items to be built upon. Most of the main issues with this game could have easily been patched out after its release to PC.
Graphically this game looks sub-par for its era at max settings and you will have to keep going back into the settings in order to have a descent frame rate due to the game insisting that your frame rate does not exceed 30 fps. Mind you this is a port to PC after debuting on Xbox 360 five months before. There is obvious clipping and at times the audio will just cut out, so if your not using subtitles you have no idea what's being said. The game could use more than it's fair share of optimization, because I get better framerate in crytek games with loads of particle effects with better framerates.
Overall this game does not feel like it was made to be on PC at all and it needed another few months of development in order to work out its serious bugs or at least a patch to correct them after release. Only worth the cash it you want to see how not to make a game.
