Conqueror's Coliseum: Underground Fight is a stage in Soul Calibur V. The combatants fight a mini-arena inside a coliseum surrounded by water. It takes place in an underground location near Conqueror's Coliseum. Underground fights only occur during night, with the stage being held up by chains attached to the statues, providing a smaller confined space for battle.
