For Fallout Shelter 1.6 update, GameSpot reported it contains some of the biggest features of the game. Bethesda described the new quests are "more substantive." Players can now head out into the Wasteland together with their Dwellers. Previously, players can only send out Dwellers to gather weapons and keep up with the action through a sort of live diary, but with the new update, players can load up a mission in their Pip-Boy and explore Wasteland with Dwellers. Furthermore, some of the new features like the Super Duper Mart and Red Rocket Fuel Stop will be familiar to avid Fallout 4 players.

There's a new combat system too. While Dwellers can still auto-attack with their weapons, players can now select opponents and direct attacks for a critical hit. Plus, there are more challenges outside the Vault. Players have to fight against new enemies like Ghouls, Radscorpions, and more powerful opponents.

Fallout Shelter is a free mobile and PC game that offers microtransactions. Currently, the game has been downloaded for more than 50 million times. According to Games Radar, over 715,740,796 Dwellers have been sent out to the Wasteland to find weapons and scrap. In addition, the gaming community has racked up more than 265,356,294 hours in the game.

With this huge success, we expect Bethesda will continuously bring exciting updates to the game. Fallout Shelter is Bethesda's first mobile game. See the game's new features below.
