Let's look the few good things in this game. There is a large amount of characters to play as, including both good and bad people. There are plenty of missions to keep you busy for a couple hours. Most of them being not too challenging.
The controls in my opinion were pretty bad. Trying to hit bats or wolves and other animals was annoying. It was difficult trying find what spacing you had to have between you and the animal. It would have been lot more helpful if there was a tutorial at the start to teach you controls, because apparently you can teleport somehow.. Also the weakest of the enemy ninja were annoying when they knocked you over on the 100 man brawl.
On some missions you cant use your ninja techniques. Which makes it extremely annoying, no matter what difficulty you are playing on. But I found any fight with another human extremely easier than killing "giant spiders" because of how easily I could be knocked down. I was sort of angry with the lack of techniques most unlocked characters have. I was also disappointed at how some characters were in the game and some, who are much cooler, were not.
