If you're looking for another COD - fast paced and unrealistic - then wait for COD MWF2. But if you're like me and like a challenge this game is for you.
The game play depends on how you want to approach each mission:
1. Run in all guns blazing and you'll find that the enemy will call for assistance and you will have teams of Ai trying to hunt you down.
2. Take your time and plan where to go avoiding the enemy until you reach you target, then execute your orders and move on to the next check point.
The nice part of the game is that you have other Special opps teams working alongside you or carrying out their own missions, so you can see other battles going on around you. Rather than being predictable and always coming through, other teams sometimes will sometimes be killed and you're left with just your unit.
The guns are nice to use and rather than being 100% accurate you find that sometimes you may be slightly off due to movement, breathing or even distance. Unlike COD where you empty a complete clip into a guy's head not missing once, this game requires that you aim and use short bursts to hit your target. Also don't forget that 1 shot can kill you and there is no magical way to heal yourself; all you can do is patch yourself up or risk bleeding to death.
So if you want a change buy this, but if you're happy running around killing as many people as you can on the same couple of maps doing the same thing over and over, stick to COD.
