Bethesda's first ever E3 press conference was a huge success, thanks in large part to epic new gameplay footage of highly anticipated games such as DOOM and what is quite possibly 2015's most anticipated game, Fallout 4. However, a small, quirky mobile spinoff of Fallout also managed to attract considerable attention in the form of the addicting Fallout Shelter.

Since its surprise E3 night launch, Fallout Shelter has proven to be a great success for Bethesda in the mobile space, and as such, the game is being expanded to feature additional content. Namely, a brand new Legendary Dweller has been added to the game in the form of Preston Garvey, and players can acquire him starting right now.

For those unaware, Preston Garvey is a character from the upcoming Fallout 4, associated with the in-game faction of the Commonwealth Minutemen. He wields the oddly named and dangerous weapon known as the Laser Musket, which can also be utilized by his character in Fallout Shelter.

For those that wish to add Preston Garvey to their vault to join the rest of their dwellers, they will need to be lucky enough to receive him from a lunchbox. Lunchboxes are the driving monetary force behind Fallout Shelter. The game has no timer paywalls or anything like that, but rather players have the choice to purchase lunchboxes with real world currency as opposed to just obtaining them in-game. Lunchboxes contain cards that add content to the vaults, including new dwellers, but whenever a lunchbox is opened, players have no idea what's going to be inside.

Fallout Shelter does a very good job of blending the Fallout universe with the usual trappings of casual mobile games, tasking players with managing the welfare and lives of dwellers living in one of the franchise's vaults. The simple but addicting formula in Fallout Shelter has launched it to massive success, propelling the game to an average of 70 million play sessions per day, and helping it to surpass mobile juggernaut Candy Crash Saga in both profits and App Store rank.

Adding Preston Garvey to the game is a smart move on Bethesda's part. Not only does it make Fallout Shelter a more desirable prospect to those that are only interested in Fallout 4, but it also helps promote Fallout 4 itself to mobile gamers. Bethesda notes that Preston Garvey is the "first" Fallout 4 character to be added to Fallout Shelter, so fans can expect other characters from the game to be added in the coming months, as well as following the launch of Fallout 4 on November 10th of this year.

Fallout Shelter is currently available as a free download for iOS devices, with an Android port expected in the coming months.
