Fallout Shelter, the hit mobile game from Bethesda, is finally available on Android, giving fans of the franchise the opportunity to live out the next few months in an ever-expanding subterranean cave while they await the release of Fallout 4 on consoles this October.

We’ve been waiting for Fallout Shelter to come to Android since it made its debut on iOS back in June. The game has been immensely popular so far, netting $5.1 million in its first two weeks despite being free to play, and it’s the perfect addiction for Fallout fans.

Fallout Shelter puts you in control of your very own subterranean cave from Vault-Tec. You’ll need to continually expand it to let new dwellers in, and then provide those dwellers with the jobs and training they’ll need to provide the rest of the community with food, water, electricity, and security.

You’ll also have to fend off attacks from raiders, and tackle random fires and cockroach infestations — all while ensuring that there are plenty of resources to go around.

Fallout Shelter is totally free to play, and you don’t need to spend a penny to have a good time and progress. However, if you choose to, you can buy lunchboxes that contain resources, equipment, and rare dwellers with special skills.

I’ve been enjoying Fallout Shelter since it arrived on iOS, and I highly recommend it. You can download it from Google Play now via the link below.
