Fallout Shelter is a casual live service game that prioritizes colony development over traditional action gameplay. Available for free on mobile and desktop, the game offers in-app purchases such as boosts and loot crates.

Combat plays a significant role in Fallout Shelter, featuring automatic combat during wasteland exploration and player-controlled combat during quests. Ensuring dwellers have optimal defensive stats is crucial for their survival in these combats.
