I use xbox 360, but it works on pc or ps3. Very easy way to mod your MW2 split screen, you can edit your prestige, xp, stats (kills, deaths, wins, losses), your killstreaks, classes (color the names, and add xbox button images) you can even edit your killstreaks and classes if you keep yourself at level 1! for example, you can just keep yourself at level 1, but with a class with an ACR, or AK-47, or Martyrdom, or with a nuke as your killstrealk! you can make yourself tenth prestige level 70, 4th prestige level 41, whatever you want! every aspect of your split screen account is changeable.
