Fallout 3: The Pitt

The Pitt opens with a desperate radio message, and a meeting with its sender, an escaped slave who claims that the leader of "The Pitt" has created a cure for mutations... and he needs you to go in and retrieve it. Do you fight your way in, or disguise yourself as a slave? Ally with the slaves, or join their Raider overlords? Theres no real right or wrong, just choices to be made, sides to be chosen and a mystery that could send shockwaves throughout the entire Wasteland.
