Modern Warfare 2

Yesterday, me and my brother got MW2 (Modern Warfare 2.) So far I have only played campaign and I have picked a couple of my favorite guns: the Striker, the FAMAS with a thermal sight and I forget the other ones. I am on the level were you start off *SPOILER**SPOILER**SPOILER*underwater. PWNED! I will add more later today when I play some Spec-Ops and possibly some Multiplayer.
