A Keeper is a person who is the best 2vs2 pilot in X-Wing vs. TIE-Fighter and X-Wing Alliance. More over, he stays up late because he is bored and fills out dumb stuff like this. Luckily, he actually lives a normal college life on the weekends. Keeper more over, challenges people to play him in previously stated LucasArts titles at www.zone.com.
That unknown pilot just scored 100k and got a 3 k/d. Must be Keeper!
