Meryl Silverburgh is introduced as the teenage niece of Solid Snake's commander, Roy Campbell, in Metal Gear Solid, where she serves as Snake's rookie sidekick. Prior to the events of the game, she gets assigned to Shadow Moses for a field exercise, but refuses to join the rebellion led by Liquid Snake and is imprisoned.
She tricks her cell guard into releasing her and then subdues him, stealing his uniform afterwards. She comes in contact with Snake via the Codec and then meets up with him afterwards. Snake rescues her from Psycho Mantis's mind control, but she is later shot and captured by Sniper Wolf.
Her ultimate fate depends on the player's actions during the Torture sequence afterwards: if the player succeeds in resisting Revolver Ocelot's torture, Meryl is then rescued by Snake after his fistfight with Liquid and the two escape together from the Shadow Moses base; if the player submits, then an alternate ending is played where Snake finds Meryl dead and Campbell reveals to Snake that Meryl was his biological daughter.
