Katana ZERO's Long-Awaited DLC Has Grown Into the Size of a Full Sequel With Over 30 New Songs
Seven years after the acclaimed launch of its neo-noir 2D action-platformer, developer Askiisoft has officially broken its silence regarding the long-awaited Katana ZERO expansion. Sharing a new development update today alongside fresh pixel-art footage, creator Justin Stander reassured fans that work is still actively underway and revealed that the project has expanded to the size of a full sequel, complete with over 30 new soundtrack tracks.
From Post-Launch Add-On to the Scale of a Full Sequel
Originally announced shortly after the base game's April 2019 debut as a free downloadable expansion meant to tie up the story's lingering cliffhangers, the Katana ZERO DLC has steadily grown in ambition over the years. For players who had begun to wonder whether the long radio silence meant the project was quietly shelved, Askiisoft's official update on X makes it clear just how massive the scope has become.
"Hi, everyone! I'm still working hard on the Katana ZERO DLC. We made it bigger. It's the size of a full sequel, plus a soundtrack of over 30+ new songs. More updates to come. Thanks for your continued support!"
Justin Stander, founder of Askiisoft
Evolving from a modest bonus chapter into an experience that matches the footprint of a standalone follow-up goes far beyond the studio's early projections. In previous progress reports, Justin Stander noted that the density of new stages, enemy archetypes, and branching narrative paths had already tripled compared to his initial outline. Reaching the volume of a full sequel is a major milestone for fans of fast-paced 2D sword action like Muramasa Revenant Blades.
Over 30 New Songs and a Glimpse Into the Cromag War Jungle
Alongside the message, Askiisoft shared a seventeen-second gameplay clip that contrasts sharply with the rain-slicked, neon-drenched streets of the Third District and New Mecca. The scene opens on a lush, sunlit jungle crossed by a quiet stream and stepping stones, where two figures in military gear pause by the water while a helmeted skeleton lies half-hidden in the undergrowth in the lower left corner.
This tropical setting points directly to the Cromag War, the brutal military conflict at the center of Zero and Fifteen's fractured memories and the secretive NULL super-soldier program. Beyond introducing new combat mechanics, the expanded campaign is expected to finally answer the biggest mysteries left hanging at the end of the original game, from the true nature of the time-bending drug Chronos to the fate of the young girl.
Equally significant is the scale of the new musical score. Since 2019, Katana ZERO has been inseparable from its pulse-pounding synthwave and electronic soundtrack crafted by composers LudoWic and Bill Kiley. With over 30 new songs produced specifically for the DLC, the expansion features an entire full-length album's worth of fresh tracks to match its sequel-sized campaign.
Where to Play Katana ZERO Ahead of Future Updates
Published by Devolver Digital and currently available on PC via Steam, GOG, Nintendo Switch, and Xbox, the original release remains one of the highest-rated indie action games of its generation thanks to its VHS-style presentation, instant-kill swordplay, and interactive dialogue interrupts. If you enjoy unforgiving one-hit-kill action games like Ghostrunner, revisiting the base campaign is the best way to prepare before Askiisoft shares its next round of updates.
My Take: Seven Years of Waiting That Evolved Into Something Much Bigger
I still remember finishing Katana ZERO back in April 2019 and staring at the credits after that abrupt cliffhanger, convinced we would see the follow-up chapters within a year or two. Waiting seven years for an expansion originally pitched as a short post-launch epilogue has tested everyone's patience, but Justin Stander's latest update makes it clear why the wait stretched out for so long.
Rather than rushing out a brief two-hour add-on just to check a box, Askiisoft let the project grow organically into a full-fledged sequel backed by more than thirty brand-new tracks. Even in a brief seventeen-second glimpse, the detail in the jungle pixel art and the shift toward the Cromag War era show real artistic ambition. Now that we know the scope rivals a complete standalone game, I am hoping those promised follow-up updates bring us a concrete release window soon.
