Check out the Half Anniversary event calendar featuring a schedule of special campaigns, rewards, and limited-time activities planned throughout the celebration period.

Arise Half Anniversary Showcase

A Song Rippling Through the Stars

A Song Rippling Through the Stars is the Season 3 chapter of the Galactic Disaster story, where the SS Nightmare crew is assigned to handle security for a major Stella Stage performance.

Chaos Emerges from SS Edenity's Base

The story centers on the hidden schemes of the Chaos Order and the god they worship, transforming the performance into the trigger for a much larger and more dangerous conflict.

SS Edenity

SS Edenity will be the new base of operations for the crew. It plays a central role in unfolding events surrounding the Chaos phenomenon, with missions and narrative arcs taking place aboard or connected to the ship.

Theater of Illusions

Theater of Illusions is the new Chaos location this season, serving both as a stage for critical story events and as a battleground where the SS Nightmare crew confronts the schemes of the Chaos Order.

New Characters

Upcoming Combatants

Get to meet the latest additions to Chaos Zero Nightmare, each bringing unique abilities, backstories, and strategies to the ongoing battle against the Chaos Order.

New Partner

Sylvia is the latest partner introduced in the showcase. The reasons behind her decision to serve Heidemarie, along with the details of their shared past, remain a mystery that will be revealed as the story unfolds.

Sortie

The Chaos that Protos and Agents will enter in Sortie contains far more diverse variables than existing Chaos. Save Data is also not retained, and instead, rewards vary depending on how far you progress in a single operation.

Combatant Rerouting Feature

Within Sortie, you can also randomly recruit additional Combatants as you progress. You can build a squad of up to four Combatants, mixing random recruits with Fate effects to create flexible and strategic teams for each operation.

5 Difficulty Levels

Additional new levels, including Hell Mode, introduce a system that further increases the challenge through up to 30 stages of risk modifiers. Experience more extreme battles and apply various penalties.

Hardcore Mode

In Hardcore Mode, losing all HP results in immediate death instead of entering Link Crashed, with additional penalties that make combat more tense and high-stakes.

Unowned Combatants are Usable

New users can still fully enjoy Sortie even without owning specific Combatants. Within Chaos, you can receive rescue signals from Combatants you don’t currently own and choose one of them to join your operation.

Strategic Setup using Various Fates

Certain Fates can be used to refine your deck in Sortie. By selecting different Fate effects throughout an operation, you can enhance combat potential and adapt your build to overcome increasingly challenging Chaos conditions.

New Currencies

Black Mass is a new currency used to buy items at the Supply Store, including Save Data editing tools, while other Sortie currencies support functions like duplication, removal, and Divine Epiphany.

Half Anniversary Celebration Coupon

Celebrate the Half Anniversary with a special limited-time coupon code. The coupon is available for redemption until the end of the event period, providing players with a generous window to claim the reward.
