The latest Fallout Shelter update 1.8 seems to focus highly on themes, with a few other goodies thrown in here and there.
According to Bethesda (via VG247), there are a few things to spruce up your vault:
Room Themes: Players can show off their Fallout 4 allegiances by building the new room, the Theme Workshop, which enables the crafting of room themes based on the four Fallout 4 factions – the Minutemen, the Railroad, the Brotherhood of Steel, and the Institute. Crafting recipes for these themes will be found on Quests, and players can turn themes on and off at will.
Holiday Festivities Coming to the Vault: For the second year in a row, holiday celebrations will return to the Vault for Halloween, Thanksgiving, and Christmas. Starting in October, Halloween-themed outfits will appear as Quest rewards and spooky room themes will become available for a limited time.
There are also some new quests thrown in:
New Quests: Update 1.8 brings a fresh batch of Quests – including upcoming special event Holiday Quests — to keep Dwellers busy finding upgrades and gathering resources from the Wasteland.
And in keeping with iOS 10, stickers:
iMessage Stickers: Since their release in September, Fallout Shelter players on iOS10 have been sharing exclusive Fallout Shelter stickers to dress up their messages with friends. Update 1.8 brings a new batch of stickers, including a set of Halloween-themed stickers just in time for the holiday.
The update is available now on Google Play, PC and the App Store.
