Fallout

Fallout is a post-apocalyptic RPG, taking place in an alternate society after nuclear war devastated the United States. It provides several means to solve individual problems, allows the player to create their own character to use in the game, and allows replaying the game due to its non-linear architecture and design.

While the core plot of the game is linear and must be completed in order to finish the game, players have a plethora of freedom in this game. Players can choose their own dialog and make their own decisions, choosing when and where to get involved (and when not to). However, it is difficult for an individual character to complete every single sidequest in the game.

Fallout takes place after World War III, which destroys much of the planet. Nations are in deep conflict after waging nuclear war for the control of more territory and the need of more resources. China invades Alaska. The United States conquers Canada. And the European Commonwealth becomes a lawless community with bickering nations attempting to take control of the western area. To protect its citizens, the United States started to build vaults, which essentially were large, underground dwellings which protected its people from radiation, chemical, and biological weapons.

Vaults can occupy several hundred people. The main character was a citizen of the Vault known as Vault-13.

The playable character's vault has a water purification controller, which purifies all the water it receives to be ready for human consumption. Unfortunately, the controller chip in the vault has malfunctioned. Without it functioning, the people cannot have drinking water available. The main character is chosen to venture out to the outside world to find a replacement chip before the vault's supply is depleted.
