The Bethesda E3 presentation was full of exciting announcements. Gamers got tons of details about Fallout 4, a first look at DOOM's gameplay, and a cinematic trailer for Dishonored 2. In addition to all of that console and PC action, Bethesda also surprised gamers with a plan to jump into the mobile market. The Fallout series will see a spin-off installment on the mobile market in Fallout Shelter.

Inspired by game's like SimCity and XCOM, Fallout Shelter puts the Fallout world in gamers' pockets. The truly free-to-play mobile game allows users to create and manage their own Vault during nuclear fallout. The game is available now on the Apple Store and doesn't require an internet connection to play.

The mobile game allows players to build different rooms, manage stats, and keep their Vault residents happy. Just like the standard installments in the Fallout franchise, this mobile experience looks incredibly addictive. Fallout 4 will have some entertaining mini-games within the AAA experience, but it's exciting to know that there will be a Fallout adventure available even when gamers are away from their consoles.

Take a look at some screenshots from the newly-released Fallout Shelter...

As gamers might expect from a community management game, Fallout Shelter players will be able to customize their Vault residents' outfits, items, and even love lives. The player can build classrooms to raise the intelligence of their community or something like a bar to raise charisma.

Fallout Shelter joins Elder Scrolls Legends in Bethesda's move into the mobile market in 2015. Fallout Shelter should be able to draw in longtime fans of the franchise, but Legends will have to compete with games like Hearthstone and Sol Forge in the digital card game market. We look forward to downloading Fallout Shelter tonight and seeing what the game has to offer.

What do you think of Fallout Shelter? Will you be downloading the app tonight? Let us know in the comments.
