Evaluation

Steel Century Groove launched on January 28, 2026 and has been actively updated ever since. Since launch, the developer (a solo developer at Sloth Gloss Games) has shipped three major updates: Update 1.5 on March 4, 2026 (custom music overhaul, Steam Deck Verified), Update 1.6 / Arcade Mode on April 30, 2026 (a full new game mode with its own progression), and Update 1.7 on June 26, 2026 (.osu/.osz chart import, new Monument Arena level). Each of these was preceded by a public beta testing period, indicating a consistent and deliberate development workflow. The gaps between major releases have been roughly 6–8 weeks. The last developer communication was on June 26, 2026 — just 16 days before today — so the developer is clearly still active. No statement has been made indicating development is winding down, and no future content has been specifically announced, but the sustained pace of substantial updates since launch points strongly to ongoing development. The two DLC items (a Supporter Pack and the Soundtrack) both released on launch day and are purely cosmetic/supplemental — there are no unreleased DLC entries on the store.
Evidence
Update 1.7 launched, adding .osu/.osz chart import support, a new Monument Arena level with destructible skyscrapers, free camera in Practice Mode, and numerous gameplay and UI improvements.

About this game

Thousands of years ago, humanity built colossal war machines to stop the apocalypse. Now they just use them for dance battles!

Using your own music or the built-in soundtrack, groove your way across a rich world, assemble the perfect mecha crew, and rise from humble beginnings to ultimate stardom.

NEW: .osz & .osu support

In addition to the automatic music analysis, you can now manually define full charts or import existing charts designed for osu!, osu!mania, osu!taiko, etc.

NEW: Arcade Mode

Skip the story and dive directly into Steel Century Groove's fast-paced, strategic rhythm battles. Complete objectives, purchase upgrades, chase high scores, then challenge the ultra-difficult upper ranks of Endless Mode. 

Additional Features:

  • Collect and Upgrade: Level up your mechs, equip them with mods, and pair them with different combinations of backup dancers.

  • Unique Gameplay Kits: Each mech has its own set of abilities, mechanics, and resources. A simple starter mech builds and spends energy, while later mechs have you maintaining an army of drones or swapping between cards in a mini deck-builder.

  • Flexible Rhythm Combat: Steel Century Groove doesn't demand a specific button press for each note. Instead, pick from your mech's kit of battle abilities.

  • No Playing the Metronome: Challenge yourself against interesting melodies, even when playing with your own music. You’ll never just be endlessly tapping out the beat.

  • No Accessories Required: Built from the start for gamepad or mouse & keyboard.

  • Streamer Mode On: Enable Streamer Mode and the game will play only exclusive, original music that won't trigger any copyright claims on YouTube, Twitch, etc.
