Korean indie game studio SurvivalTaktix is developing a new dice-based Roguelike builder, Seferia: Matrix. The game combines the "combination and Build" concepts of traditional deckbuilders with dice mechanics: players need to roll and lock five dice, complete a "Hand" through different face combinations, and release corresponding magic.
Seferia: Matrix will officially launch on November 10, 2026 (Beijing Time). A free demo is now available on Steam, allowing players to experience the core gameplay and add the game to their wishlist.
Five dice are your magical deck
In Seferia: Matrix, players arrive at the Magic Academy in Seferia, a powerful magical nation. But unlike traditional Deckbuilders, your "cards" are replaced by five dice.
In combat, players continuously roll dice using the Lock & Roll mechanism, choosing which faces to keep. When the five dice form a corresponding combination, a Hand is completed, releasing the associated spell.
Thus, every Roll represents a choice: continue pursuing better dice faces, or lock in the current combination? Should you cast the completed spell immediately, or keep building towards a higher-yield combination?
As the game progresses, simple "dice rolling" gradually evolves into strategic choices revolving around probability, resources, and Builds.
Unhappy with the dice result? Change it directly
Randomness is part of dice-based gameplay, but Seferia: Matrix does not want players to merely accept luck passively.
Sigils in the game help players change missing dice faces, creating new possibilities for combinations that were previously impossible. Therefore, players need to think not just about "what was rolled this time," but also how to actively influence the outcome using available resources.
Meanwhile, the game provides over 300 upgrade options, allowing players to continuously adjust and strengthen their Build. Different upgrades can modify and enhance spell effects, creating increasingly rich combination possibilities as the game progresses.
As dice faces, Sigils, upgrades, and spells begin to synergize, the effect of a Build can be amplified repeatedly, allowing originally ordinary spells to eventually deal extremely high damage.
Three Magic Schools, freely decide your build path
Seferia: Matrix currently features three different magic schools:
Arcana, Nihila, and Materia.
Different schools have their own spell systems and unique abilities. For example, Arcana studies the power of the Mystic Universe and has its own Signature Spell.
However, players are not completely restricted to a single school.
The game allows players to choose courses across different magic schools, combining abilities from different systems into their Build. As a run progresses, players will continuously face new upgrades and construction choices, gradually forming their own unique magic system.
The end of a run doesn't mean starting from zero
As a Roguelike, each challenge in Seferia: Matrix brings different upgrade choices and Build paths, but the game also incorporates cross-run permanent progression mechanics.
This means that even when a Run ends, the training and growth gained within the Magic Academy are retained.
In-run random Builds and out-of-run long-term growth together form the game's loop: constantly try new dice combinations, Artifacts, and magic routes, while gradually strengthening your character to create more possibilities for the next challenge.
Additionally, players can visit the shop during gameplay to purchase new Artifacts and Items with earned resources, further adjusting their current Build.
A new attempt from a Korean indie developer
Seferia: Matrix is developed by the Korean indie game studio SurvivalTaktix, led by Ho-Jeong Lee, who has years of experience in the game industry. Previously, he participated in various commercial and indie game projects, with development experience in game systems, economy, and narrative design.
During development, Seferia: Matrix has also participated in local indie game events in Korea.
The game was selected for the Unite Seoul 2026 Indie Game Showcase in July 2026; it was then chosen as one of the Top 52 in the IndieCraft 2026 Community Division from a record-breaking 417 submissions, and showcased in September.
For this indie-led title, it also gave Seferia: Matrix more opportunities to meet players before its official release.
