Okay, by setting this game up as better than MW2, I'm probably going to incur the wrath of some CoD god somewhere. However from my perspective it's true, the whole dropping from orbit thing is pulled off excellebtly and the multiplayer is excellent. The jet pakcs make a big difference to gameplay.
The important thing to remember about this game, is that it's more about tactics than having incredible reflexes. If you enjoy games where you have less than a milisecond to react to seeing an enemy this will not be for you. Killing enemies is extremely hard as everyone has lots of shields and armour, and nearly everybody will have a repair tool on them. However this means that when you do manage to kill somebody, either through teamwork or sheer determanation, it's really quite satisfying.
The only thing that lets the game down is the campaign, it was simply un-interesting. Very little plot, and very badly executed. There's nothing to set it apart from the multiplayer, just that you fight AI instead of actual people.
So if you don't like 'unrealistic' games, this isn't for you. If you don't like 'slow' games, this is for you. However, if you like relaxed games which require a use of tactics, then I reccomend this game.
