Simply Magnificent!
Another noticeable thing were the cleverly named achievements/trophies. I thought they were an interesting overview of what the last game was and what the players went through.
Throughout the missions you notice that there are more than one route to the end point giving you more freedom of choice to get past through the massive environment through the game. even though the game is linear for the most part the big beautiful environments that you are placed in make it less therefore giving you the feeling that you're actually in a city rather than a tunnel just shooting enemies and proceeding through a very narrow and straight path like most other shooters nowadays.
Crysis 2 does a fantastic job of not boring the player with the typical running and gunning style like most of today's fps games. Instead it leaves the choice up to the player to choose how they want to use the environment and the style of play that the player finds the most intriguing to use within the game. Add to that are the brilliant set pieces that happen along naturally within the well crafted storyline and you will get Crysis 2.
