So had a power level over 9000 but then I took an arrow to the knee

The singleplayer campagain is phenominal! Lots of cinematic effects and heart pounding moments. The Spec Ops co-op missions are also pretty fun. That however is where the compliments end. If you are buying this game for the multiplayer and are hoping for an ultra realistic style of war game you will not get what you paid for. The style is very unrealistic, many unbalanced weapons, horrible lag compensation, no dedicated servers, no punkbuster (Infinityward got lazy and felt like using VAC instead for its security engine, which is designed for the source engine, not mw2.), conintuing updates for this game have all since ended on IW's part due to their legal battles, map packs for multiplayer are too expensive for too little, and the list goes on. If you are looking for a realistic war game go pick up a copy of Battlefeild: Bad Company 2. Its 30$ cheaper and its multiplayer is far supperior to MW2's.
