Having read many of the reviews that this game has been given, i have wondered wether or not the people have actually played the game through to completion!! Let me explain why, the first part of the game you are presented with this god-like character who has all of the upgrades, then you are placed 18 days or so into the past where you have just escaped the labs where you were created. I don't want to say too much about the story as that would give all the twists and turns away. Then you start without any power ups and so have to go through the process of upgrading yourself through the collection of genetic material.
One of the finest points of this game, in my opinion, is the Web of Intrigue. This tells the story behind the events in the game, it reminded me of the '1000 years of dreams' in lost odyssey. Key characters in the game show up when they are near you, and if you consume them, literally, then you get all of their memories and the more you find and consume the more of the web opens up.
Controlling the main character is very easy, as the game is incredibly responsive, especially as you power up your character your parkour becomes very impressive. The offensive upgrades are brilliant, they cover all the main hand to hand combat situations that you would expect. i.e. the fast but weak claws, the very long reaching whip, or the super weapon, the blade. Defensive upgrades are also very good, there are only 2 though, shield and armour. As you progress you will also get the opportunity to drive / pilot tanks and helicopters, which have the most powerful weapons in the game, great for clearing out infected hives or military bases quickly, just don't stay in one place too long!
There are effectively two ways to play the game, the first is to kill everything that moves or the second is to blend in with the crowd, as when you consume them you can make yourself look like them. As the title to my review suggests i went all out destruction. There are of course downsides to this, such as the constant intrusion of the military, which as the game progresses can become difficult but with a few well timed sneaky consumes or a flying attack against the strike teams then you can easily destroy them.
The game actually takes place on the island of Manhattan and you are free to explore it right from the start, which is excellent, its worth taking a look around as there are lots of things to find.
This game is truly excellent, the graphics are superb as well as the game mechanics. This is the first 360 game where i have actually wanted to get all of the achievements. If you are a fan of action adventure games with a touch of an rpg - esque upgrade system you will love this game.
