best game mode for xp mw2?

best answer
  • Right now the best way to reach the top rank is through Ground War. The 32vs32 mode is massive — it takes a long time to complete a match but if you’re wracking up tons of kills you can earn huge XP rewards. A single match can net you 20000~ XP. Keep in mind if you’re playing for kills you’ll need to change your playstyle slightly.
