Chaos Zero Nightmare Celebrates Half-Anniversary With Major Update – Smilegate Coming to Los Angeles for Anime Expo in July
Santa Monica, CA - April 29, 2026 - Today, Smilegate has released Chaos Zero Nightmare's biggest update yet, “ARISE.” The studio has also announced they will be bringing both Chaos Zero Nightmare and Miresi: The Invisible Future to Anime Expo in Los Angeles this July.
In this major Chaos Zero Nightmare update, players can expect:
Sortie Mode – This new mode expands on the game's roguelike deck-building through evolving routes, shifts in party composition, and higher-risk “Fate” driven decision-making. Unlike existing Chaos mode content, Sortie removes save data entirely, emphasizing a strict run-by-run strategy.
System Overhauls – Changes have been designed to reduce repetition and improve long-term engagement, including Battle Skip Mode for Chaos content, reduced Chaos-mode fatigue, and major improvements to reward pacing.
The update also removes seasonal restrictions on The Great Rift Save Data Mitigation, allowing players to carry and remix past builds across seasons for the first time.
Season 3 – “A Song Rippling Through the Stars” introduces a new narrative arc set aboard the SS Edenity, alongside new Chaos content, Divine Epiphany cards, and the fully realized “Persona Cards” system.
A new Seasonal Combatant, Heidemarie, also joins the roster, featuring a unique “Link” combat mechanic that synchronizes and chains card effects.
Spiral Tower of Screams – The tower-climbing mode sees its full release alongside a strong Half-Anniversary reward suite, including a ★5 Combatant/Partner Selection Ticket and up to 70 free Rescues.
Smilegate has announced they will be attending Anime Expo in Los Angeles this July for the very first time, showcasing both Chaos Zero Nightmare and Miresi: The Invisible Future. Smilegate's booth will host a variety of interactive events, including giveaways and cosplay activities. Miresi: The Invisible Future will also include a playable demo zone where attendees can experience the game firsthand.
“As this marks Smilegate's first opportunity to meet North American and global users through Anime Expo, we are committed to delivering a high-quality and engaging booth experience leading up to the event in July. We also ask for your continued interest in upcoming updates shared through the brand page.” - Lee No-ju, Director, Smilegate
Since launch, Chaos Zero Nightmare has been steadily evolving its roguelike systems, and “ARISE” represents its most comprehensive step forward yet, balancing deeper strategic expression with reduced friction and improved accessibility.
Chaos Zero Nightmare is available now and free-to-play on PC, iPhone and Android.
