Gates of Hell Arena is a game mode where Dante can grind through waves of enemies. The player must defeat the waves within the alloted time. There are a total of 50 waves, at the end of which the "Gates of Hell" achievement/trophy will be unlocked. When starting the Gates of Hell Arena, the game will prompt the player to choose a save file, from which all upgrades, abilities, magic, relics, and souls will be available. All purchased and unlocked costumes are available here.
Players fight waves of increasing difficulty starting with a 5 minute time limit (For the whole mode) which can be increased by: Completing a wave, punishing/absolving enemies, and completing a wave without taking any damage (Untouchable). After all of the enemies are defeated, the gates are opened, but the next wave will not start until the player goes through them.
