Set in the aftermath of a world-wide nuclear war, Fallout will challenge you to survive in an unknown and dangerous world. You will take the role of a Vault-dweller, a person who has grown up in a secluded, underground survival Vault. Circumstances arise that force you to go Outside – to a strange world 80 years after the end of modern civilization. A world of mutants, radiation, gangs and violence.
Your immediate task is to find a replacement for the broken water purification controller chip. Without that chip, your fellow Vault dwellers are doomed to dehydration or will be forced to leave the safety of the Vault for the Outside.
The core of the game revolves around your character. Fallout uses a skill-based system to allow you to fine tune your character. As you gain experience (roughly half from combat, the other half from solving adventure seeds and non-combat events), your character will grow as you determine. Combat in Fallout is tactical turn-based. You can take as much time as you need to make decisions. Choose from different types of attacks, with a variety of weapons and attack skills.
