Boss Rush of the Endless is a standalone challenge mode that drops you into an unbroken gauntlet of boss fights. The moment one boss falls, the next is summoned. A kill counter tracks your streak. How far can you go before your candle goes out?
Boss Rush uses a separate game state from your main save files. Starting a Boss Rush run does not overwrite or affect your regular saves.
The Boss Rush mode draws from the full pool of Fear & Hunger bosses, including:
Bosses are drawn in a randomised order. No two runs are guaranteed to present them in the same sequence.
As your kill count rises, progressive scaling applies stat multipliers to each subsequent boss:
The scaling stacks with Multiplayer player-count scaling and any Difficulty Mods you have enabled.
