Go to Headquarters
use a riot shield and capture the HQ
go in search and destroy, i find is the easiest. but leveling quicker always depends on how good you are.
Play a lot of Search and Destroy it is by far the easiest way to level up.
Play online
Buy it.
Play kill confirmed it levels you up quickly. or get a lobby of your friends that way your all on one team and play search and destroy it increases your chance of survival.
Be really really good at it.
The easiest way that I have found to level up quick is to play Headquarters Pro or capture the flag. If you are wanting to level up quick I would play one of those, I wouldn't play Teamdeath Match or Free for All, if you want to level up quick.
you cannot do the elivator in favela anymore they have patched it but if you could i would give you a tutorial but you cant sorry
modern warfare 2 all the way!!!!!!!!!!!!!!!!
play day and nyt
No. You cannot change your badge on this game. The only way is to level up or prestige.
You need to get to rank 50.The only way to unlock the Javelin is by playing the Multiplayer on Modern Warfare 2, just like to do with every other gun. It is unlocked at level 50, and when you prestige, you will have to reach level 50 again to unlock it, like the other guns.
