'Modern Warfare 2' is good. I can't believe there are already cheaters.

The beta received a lot of criticism from high-skill players used to a game that catered directly to a fast-and-aggressive playstyle, but the more realistic mechanics seem just fine to me, and should benefit the swath of average players who comprise the majority of Call of Duty players. In a game that bills itself as tactical, you shouldn't be rewarded for bullrushing a room full of enemies just because you have twitchier muscles and can move like a mongoose that spent the past hour mainlining a cocktail of G-Fuel, Red Bull and Mountain Dew. Real people do not leap out of a slide and hit headshots. Faster players are always going to have better reflexes than your average 40-year-old playing Call of Duty; they don't need to be aided by unrealistic movement mechanics too.
