Even a decade later, the DLC for Harmony of Despair remains unique. Unlike Dead Cells or modern Roguelites, this game offers a "Chaotic" difficulty.

Without the , you cannot play as Maria—who is widely considered the most broken (and fun) speed-run character due to her invincibility frames on doves.
