It is a Hack , obviously , for people with no life
you don't haha,you play the game correctly
In MW2, most game modes give you 100 XP per kill. But Search and Destroy and possibly Sabatoge, each kill will give you 50 XP.
kill people, get xp...just like MW2
ADD warkid10 FOR xp & C-LOBBYs PS3
Every kill you get in mw3 = 50 weapon xp no mater how many points per kill for normal xp. Say you get a kill in kill confirmed you get 50 xp and 50 weapon xp, if your playing search and destroy you get a kill (500xp) the kill was a head shot (+500xp) the kill was payback (+50xp) the kill was a comeback (+100xp) and you got the kill in final stand (+500xp) (final stand kills, normal xp kills, and head shot xp are different by game mode) this adds up to 1650xp for the kill but you still only get 50 weapon xp. challenges are different the amount earned from a gun challenge results in the same amount of weapon xp a mastery gives 10,000xp for player and gun.
Play Demolition, it gives you the most xp.
It all depends on the game mode and other factors. For instance playing Team Deathmatch for a simple kill you will receive 100 xp. Getting a kill from a distance or a "Long distance shot" you'll receive 150 xp. Avenge a team mate and you'll receive an extra 50 xp on top of the 100 xp for the kill. If you're playing something such as Headquaters then you only get 50 xp per kill instead of the usual 100 xp but all other bonuses apply (You can get defence and offence kills on certain game modes which give you 200 xp for the kill.)
While playing a game type, look at the bottom of the screen and you will see a yellow bar, that is your XP. Also after the game press "Y" and you can see your XP.
each game has different game points like S&D 50 points per kill, tdm 10 points per kill or free for all 5 points per kill and you might of been on xp week which give you more points double points or you could of killed someone and completed a challange hope this helped
The game of the year was in Windows XP/VISTA as was MW2 & WAW, Black Ops was in Vista/7/XP
you get 120 xp per monkfish in rs
500 xp per hour for bandits
Its like any other lobby, but that its in private match. Any kills earned in the host's lobby count toward your actual live rank, and so when the host sets each kill to 4.5 million xp you actually get 4.5 million xp and rank up usually 70 or so levels. So as long as your in the lucky lobby, you get the xp to become tenth.
