The latest Fallout Shelter update is available now, and it adds a number of new features, including pets.

"Vault-Tec research has shown that 4-legged companions can have a profound impact on Vault happiness and productivity," says the update's description.

You're now able to evict "lazy layabouts" from your vault, and your Dwellers have some new pickup lines and conversations.

There is a new Sell All function for when you're clearing out your inventory, and there have been some Dweller management improvements, along with new objectives.

The previous Fallout Shelter update added Survival Mode and cloud saves. In IGN's review of the game, we said that Fallout Shelter is "fun for a few days, but lacks long-term appeal."
