The game is good. But I was not impressed by it. I didn't find any kind of satisfaction playing it, and it got to the point where I found it pointless to kill the enemies other than to simply advance.
If there was some kind of reward for killing, then maybe I could have been more interested. Maybe this is because I didn't play the first 2, and I was not used to the gameplay. Regardless, I'm glad I didn't waste my money on this game.
