Graphics and gameplay are top-notch, and the characters are insainly funny. You'r bound to love it.
This game also carries with it some good characterisation, witch is always a plus, because these characters are really hilarious. But the main part in this genre will always be a great innovative combat system. Now compared to many other modern shooters, the combat system is not all that different, but why change something that already works so well. Because of this very element it is easy to adapt to the game, witch takes the load of many backs as people are already familiar with the movement of the character, but a few things have been changed since the first game, and for the better. No longer do you have to worry about healing yourself, just find some cover and wait till you guy breathes normally, and go back to blowing things up, pure and simple.
This game will take you through several different landscapes around the world, most notably the beautiful valleys of Peru, with huge green mountains stretching towards the sky on each side of the valley, the colors are fabulous and the small villages seem very realistic.
Both graphics and gameplay is great stuff, and it is a lot of fun listening to the short conversations from the other characters, this game is just plain-old FUN.
