Fallout: A Post Nuclear Role Playing Game is a 1997 role-playing video game developed and published by Interplay Productions. In a mid-22nd century post-apocalyptic and retro-futuristic world, decades after a global nuclear war between the United States and China, Fallout's protagonist, the Vault Dweller, inhabits the underground nuclear shelter Vault 13. After customizing their character, the player must scour the surrounding wasteland for a computer chip that can fix the Vault's failed water supply system. They interact with other survivors, some of whom give them missions, and engage in turn-based combat where they battle until their action points are depleted.
