Fallout Shelter is a game set in the Fallout universe. It is something of the odd one out, as it forgoes the usual Bethesda RPG format for a colony management-style game. Since launch, the game has been refined, with heaps of content being added. However, it does now have the dreaded cash shop, for players to buy boosts and items. Fallout Shelter follows the franchise cannon in most respects, and players of other games in the franchise will instantly feel at home.
