The game, while something very new, has a lot of things that make it less of the masterpiece you expect from this game.
Then, there's the guns. This is what I feel held the game back from being so great. There are these perfect times when you're swiftly moving around the game and suddenly you come up to these enemies with guns. Most of the time, you can't run away from them, so you're going to have to fight them. Fighting the enemies later in the game gets so frustrating, because there are so many of them, and you're getting shot at while you're fighting another one, and you die. And die. And die. I could not count the number of times I died in this game.
Also, where I feel the game really shined was when you were running across the rooftops, not inside a mall. The inside parts weren't terrible, they just paled in comparison the the rooftop sequences.
Okay, that's my review. Hope you liked it!
