Final Atrium is the final stage in every story mode, and is unlocked for use in multiplayer and training mode upon any story mode's completion. Alternatively, purchasing the character color bundle DLC will instantly unlock all stages, including Final Atrium.
As a display of power (or perhaps blind rage), the Skullgirl has destroyed the massive cathedral which sheltered her. Fragments of broken Trinity statues loom overhead as a full moon shines down onto the arena. With little left to stand on for support, the Skullgirl's raw energy functions as a makeshift floor in the form of thick, bright blue strands with skulls laced into them.
- The track that plays on this stage is officially called "Skull Heart Arrhythmia"; an arrhythmia is an irregular heartbeat.
