I normally use the guided missile or Counter UAV with the Harrier and either the Pavelow or Chopper Gunner, but I decided to mix it up one match and selected Harrier, Emergency Airdrop, and Pavelow. The kills needed for these three are 6, 7, and 8. When I got all three in a row, I got a new title. I say challenges because I think it’s a challenge to complete the tasks in order to get all the titles and emblems. And they’re hidden because there’s no instructions on how to unlock all the titles and emblems!

I got booted with this message after watching a replay of a guy using an aimbot to instantly target my head while simultaneously being able to see everyone in the game, right through the walls.

Call of Duty: Modern Warfare 2 on the PC does have a config file with settings that are modifiable. You can open the config file in notepad and edit away. Don’t remove anything or add extra lines or your game will crash. It’s also against your legal terms of use psycho-babble i’m sure.
