A description of how to unlock the achievement and a listing of people willing to help others unlock it.

How to unlock:

The achievement is still unlockable, even after the closing of GameSpy's servers.

To unlock the achievement you'll need to be in a game lobby (the screen before you are in first person). So if you are in control of your character and then invite someone the achievement will not unlock. The achievement will only unlock if they are in the lobby.

There is a 12 month time limit for people to share the achievement with others.
