When you think of mobile games, there’s a good chance that Bethesda might not have popped in your mind, but if you recall, the company did try their hand at launching a mobile game with Fallout Shelter from 2015. The game turned out to be quite a huge hit and reportedly raked in $5.1 million in its first two weeks.

Fast forward to two years later, it seems that the game is still going on strong because in a blog post on Bethesda’s website, the company has announced that Fallout Shelter has managed to surpass 100 million users to date. Of course whether or not all these users are still playing the game, or how many are playing the game at the same time is unclear, but to rack up that many players in the course of the past couple of years is still an accomplishment.

According to the company, “That’s more than a BILLION Dwellers sent out to explore the Wasteland, scavenging for materials and battling Raiders, Radscorpions, and Ghouls! More than 7.5 billion game sessions have been played for more than 385 million hours. Check out the infographic for even more fun stats about Fallout Shelter’s 100 million users!”

To celebrate the game hitting 100 million users, Bethesda has announced that they will be kicking off a 5-day celebration. This will begin today, the 15th of September, and will see players receive significant daily rewards that is expected to amount to about $10 of in-game loot, which includes Lunchboxes, Nuka-Cola Quantum, and various special items.
