<ul data-eligibleForWebStory="false">Borderlands 4 is shifting its focus to a more serious narrative tone by cutting back on 'toilet humor' and irreverent meme culture.The game is set on a prison planet named Kairos ruled by the Timekeeper who controls the inhabitants with remote killswitches called 'bolts.'Different factions like the Outbounders, Augurs, and Electi, each with a Timekeeper general boss, add depth to the game's setting.Developers aim to create a sense of dread about the Timekeeper, offering a new twist on the main villain character compared to past Borderlands games.
