Challenges
In Modern Warfare 2 (just like past games) there are challenges in the barracks section of multiplayer. The full list can be viewed and downloaded at the top of this guide. The majority of challenges that people tend to go for are challenges for guns that unlock attachments. There are also challenges for special camouflage on guns too. The other challenges give callsign titles and emblems plus XP. All of these can only be unlocked once per prestige.
Some of the challenges don’t give the full set until a later level or when more things become available. For instance you unlock the Equipment Challenges and Perk Challenges but not all challenges in those sections are available until you unlock the other equipments and perks.
Basic Training is Start to Backdraft (2 sets)
Operations is Start to Sabotage Victor (2 sets)
Killstreak is Start to 21 Ton Giant (2 sets)
Precision is start to Perfectionist (2 sets)
Finishing Moves is start to OG (2 Sets)
Humiliation is start to Cruelty (2 Sets)
Payback is one set from start (1 Set)
Elite is start to Counter-C4: I (2 sets)
Intimidation is start to Carpet Bomb (2 Sets)
Once you prestige they reset and you can unlock them again when they become available. If you do the challenge before it becomes available then you will not get the XP bonus, title, emblem, attachments, or camo. Once you prestige the first time you get special “Prestige Challenges” which never reset and roll over through the prestiges. I talk about this in the prestige section.
Unmarked Challenges
There are many challenges that don’t appear in the barracks which you can get titles for and XP. Like most challenges you can only do them once per prestige. Most of these you can do once you unlock the challenges section. Some you have to wait a little later in the levels. I’m not sure of all hidden challenges available. Some include:
Radiation Sickness – Get nuked by an enemy +1500 XP

XP Bonuses
In Modern Warfare 2 there are many different XP Bonuses you earn during matches which give you extra XP added to the regular kill and challenge XP, but sometimes they only give you extra XP up to a certain point OR they don’t give any XP at all but pop up the same as the other XP Bonuses. During gameplay a message pops up giving the title and a little description of what you just did. I believe I have listed all in the game:

Match Bonuses – After every round or match you get a bonus. Depending on the amount of kills you got, the points you earned in objective matches, the length of the match, winning the match (seems to multiply by 2), and your rank the points can be low as 100 XP in the lower ranks to as high as 5000+ XP in the later ranks. If you leave the match before the end of the game then you will lose your match bonus.
