After destroying the charts on the App Store, Bethesda's free-to-play game Fallout Shelter is now out on Android. Which means it's also available on PC, if you're willing to jump through some hoops.
As this guide by Ian over at PC Review explains, all you need to do is download an Android emulator -- in this case Bluestacks -- install it and then head over to Google Play from within the virtual environment.
If you don't have a Google account, you'll need to cook one up to get access to the market. Otherwise, it's a straightforward process -- find the game, grab it and play.
Seeing as the game was designed with mobile devices in mind, you should have no problems running it on any PC made in the last 400 years. Unfortunately, if you're still cranking out Excel spreadsheets on a stone tablet, you're out of luck.
Everyone else though, enjoy re-populating the wasteland on your desktop!
