The Borderlands series games give players a variety of ways to obtain loot, and while the vast majority of loot one gets will be from killing enemies and opening chests in the game world, it's also possible to get some by redeeming Shift codes. Shift codes return in Borderlands spin-off Tiny Tina's Wonderlands, with players able to redeem the Shift codes in exchange for Skeleton Keys that can be used to open the chest in Brighthoof for some free loot.
