Great Bond game, lots of fun.
The game uses a good cover system, somewhat similar to Quantum of Solace. Jumping from cover to cover is pretty easy, as is firing from cover. Although like any cover system sometimes you can put yourself in fire by accident instead of taking cover.
What truely makes this game and the action is the melee system. Taking down enemies is fun, and rewarding. Every time you take down an enemy using melee you are rewarded with a focus shot. Which is basically and instant kill. You can save up to three of these to use at any time. I prefered to use them on enemies at a distance that can't be reached with melee attacks.
The game also feature a wide variety of weapons for you to use, and if you find your self running out of ammo simply pick up a weapon from a killed foe.
The game has a lot of variety as well, there are car chases that are exciting(although sometimes too long), and every level is different from the one before. You won't get bored with the same old locals. Boss battles are done real well too.
The game features a muti-player as well. I tried it out but felt it wasn't something that I would want to continue to play. There are other multi-players I'd rather waste my time on (eg. BF 3). And having the focus kills in multi-player was a little annoying.
Anyways it's a great game, highly recommended, and just the right price now.
