In Metal Gear Solid, Campbell comes out of retirement to command Solid Snake once again. Campbell has more of a personal stake in this mission, as his niece, Meryl Silverburgh, is held captive by the revolutionary force Snake is battling. While Campbell is initially forced to keep a number of secrets from Snake, he gradually reveals more and more of them as the story continues, until, finally, Campbell is briefly arrested. However, he is exonerated after Solid Snake defeats Liquid Snake. He reveals in the alternate ending of the game that Meryl is actually his biological daughter.
