After having this game for a few days now I can definitely say that this game certainly lives up to the hype.
The single player is truly outstanding. The graphics are the best I have ever seen in any game. They have kept the same basic cover,aiming & shooting system, but tweaked it very slightly which makes the cover system a vast improvement. (no more getting stuck on walls etc!)
The scale of the single player campaign is increadable. Gears 1 was very compact and based more on small fire-fights, not so in gears 2. You will face massive battles against some truly massive new locust and there is more of a sense of being a part of a massive army, rather than just your own squad.
The story line is absolutely epic. It really has to be experienced. there are some truly fantastic moments throughout. The music is also brilliant, some of the best I have ever heard in a video game. The whole general presentation is outstanding. The single player is worth £40 alone.
On to multilayer, which I'm sure will be the most popular part of this game. I have to say I agree with all the critics in horde mode (where you take on up to 50 waves of very increasingly difficult enemies. It is sooo much fun! Up to five player can play on any of the 15 maps and it is the most addictive multiplayer mode I have every played!
Other game modes vary from standard warzone, submission, annex etc. which are all very solid. The introduction of a party system makes joining games so much easier, and now you can jump in with friends very easily.
I'm sure this will be the most played game on live for quite some time.
Over all I can hardly find any faults with any part of this game. This is truly the best game I have played, ever. Believe the hype, even if you didn't buy the 1st one, if you have a 360, buy now!
