How do you rank up fast in modern warfare 2?  

yea its hard to level up once ur high. You can do it faster doing the big team games. Well thats what my friend said and hes like level 60 in like 2 weeks. Ive been playing for awhile and still not that high hahahaa..... Im kinda a noob and those pros be killing me down. Pro get most exp=[ dang tactical nuke=[

there are many ways but if you cant be stuffed you can boost with a friend in 3rd person cage match. i hate boosting lol i get bored after a minute and start mucking around so they know not to ask me lol. at the moment im on my 3rd prestige. the hype for the game has sropped dramatically 4 me since their are all these little kids running around being noobs

There was a glitch you could use that made you level up REAL fast...try youtube and look up COD MW2 leveling glitch. Pretty cool

you can always boost with a friend, it's not cool, but if you need the xp to rank up than its an option. boosting can be done with a riot shield and a weapon like a light machine gun or striker shotgun. hide out in a public mtch with your friend. somewhere where nobody goes on the map. and take turns shooting eachothers riot shield and watch the xp stack up. i wouldnt do it, but its an option.
