Solo Leveling: KARMA Gameplay Breakdown — Shadow Army, 200+ Buffs and the 27-Year Monarch War

Netmarble and developer Netmarble Neo held a media showcase at Tokyo Game Show 2026 for Solo Leveling: KARMA, releasing both a Game Overview trailer explaining the roguelite action RPG’s core systems and a Cinematic trailer setting up its original story. Together, they’re the fullest look yet at how the mobile game translates Sung Jinwoo’s world into something playable rather than just another cutscene-driven tie-in.

What Netmarble Confirmed About the Build Shown at TGS

Netmarble’s presentation confirmed the TGS demo included more than 200 types of buffs and 8 playable characters. Jin Seong-gun, Head of Development at Netmarble Neo, said the team “implemented the ‘Shadow Army’ — a core element of the original work — as playable characters that can be directly controlled,” rather than the passive summon system the ability functions as in the source manhwa/anime. That’s a specific, quoted confirmation, not an inference from footage: the Shadow Army fights as controllable characters in KARMA, not just AI-directed backup, which is a meaningful departure from how most Solo Leveling adaptations have handled the ability so far. Japanese actor Kanata Hongo appeared at the showcase to demonstrate two modes — Story Mode and Survival Mode — though Netmarble hasn’t detailed how the two differ structurally beyond their names; treat Survival Mode as likely a separate, replayable challenge format rather than assume it mirrors the main campaign until Netmarble states that directly.

The showcase itself was staged at the Netmarble booth, with Hirokazu Yamashita, Head of the Business Division at Netmarble Japan, and Jin Seong-gun jointly introducing the game’s systems to press and attendees. That’s a detail about how the reveal was delivered rather than the game itself, but it underlines that these weren’t just marketing-copy claims — they came from the development side directly, in a format that let outlets ask follow-up questions on the systems Netmarble was demonstrating live.

Weapons, Builds and the Roguelite Structure

According to reporting on the Game Overview trailer, Sung Jinwoo isn’t locked to a single weapon type — daggers, scythes, and bows are all shown in play, and players combine equipment with the 200+ buffs to shape a build during each individual run, consistent with roguelite structure elsewhere in the genre. Netmarble’s own material frames Hunters and Shadows as having genuinely distinct battle styles rather than reskinned versions of the same moveset, though the publisher hasn’t detailed how deep the character roster goes beyond the 8 shown at TGS, or whether that number represents anything close to a final lineup.

The 27-Year Monarch War: New Territory, Not New Canon

The Cinematic trailer’s own text frames the setup directly: “The 27-year-long Monarch War, unveiled in the original story. Inside the dimensional gap, Sung Jinwoo’s lonely fight continues! Hunters corrupted by an unnatural power… Who controls them from the shadows…?” This period was referenced in Solo Leveling’s original story but never shown in detail, which gives KARMA space to build an extended arc without simply re-staging scenes from the anime or manhwa. It’s best described as exploring an untold period of the story rather than adding new canon — Netmarble hasn’t used the word “canon” in its own material, so that distinction is worth preserving rather than assuming.

Reporting on the trailer’s footage describes corrupted, “evil” versions of familiar hunters including Cha Hae-In, Go Gun-hee, and Choi Jong-in appearing as enemies during Jinwoo’s dimensional-gap fight — a way of putting recognizable faces from the anime and manhwa into a genuinely new conflict rather than introducing an entirely unfamiliar cast. Troy Baker is confirmed as the English voice of Antares, the Monarch of Destruction, described as the story’s final major encounter, alongside Aleks Le reprising Sung Jinwoo. But the cinematic trailer poses “who controls” the corrupted hunters as an open question rather than answering it outright, so treat Antares’s exact role in that specific mystery as still unconfirmed rather than settled by the trailer itself. It’s the kind of hook a cinematic reveal trailer is built to raise, not resolve.

Platforms, Release Window and Pre-Registration

Solo Leveling: KARMA is confirmed for PC, iOS, and Android, targeting a 2026 release window; Netmarble hasn’t announced an exact date. Pre-registration opened September 16 on the Google Play Store and Apple App Store, but specifically for Korea and Japan — not a global rollout yet. Registered players in those regions are set to receive a Sung Jinwoo Predator Outfit, a Shadow Monarch Halo Decoration, a Monarch’s Box, a Hunter’s Box, and a Secret Support Card, according to Netmarble’s own reward listing.

What’s Still Unknown

Netmarble hasn’t detailed the full playable roster beyond the 8 characters shown at TGS, confirmed pre-registration availability outside Korea and Japan, or explained how Story Mode and Survival Mode differ in structure or objectives. Nothing here should be read as confirming a final release date, a complete character list, or how directly the corrupted-hunter mystery resolves — TGS answered what kind of game this is and what its central conflict looks like, not how the story ends.
