Call of Duty:Modern Warfare 2

Mongoose, stopping power is absolutely essential. If you like to run and gun, use a silenced P90 with Marathon, Steady Aim and Stopping Power. With steady aim your hip fire accuracy is almost as good as aiming. When I use that, I can pretty much dominate a game.

Reloading after a skirmish is second nature to me. I do it almost automatically but it gets me in trouble sometimes because I'm reloading and then here comes someone else. It really depends on the situation. In a crowded area I try to get into a corner or something and reload.
