Mayhem Mode

Mayhem Mode is a game mode introduced in Borderlands 3. Mayhem Mode is activated upon the completion of the main story of the game.

Characters are taken to a mysterious terminal aboard Sanctuary III that can enable four difficulty levels, from one through four (previously three). Taking on one of these Mayhem Modes ups the ante on risks and rewards across all worlds: enemies get increased health, shields, and armor, in exchange for bonus cash, Eridium, experience points, and chances for better loot.

Mayhem Mode applies Mayhem Mods to any planet visited and can require new playstyles to be adapted in response to a random selection of modifiers. Modifiers for the current map may be viewed through the map screen.

Mayhem Mods are determined when a character enters a new area for the first time, traveling back to an area you have left does not change the mods applied to that area. Changing the Mayhem Level, exiting the game, or returning to the main menu will reset all mods.
