In the twilight of the solar system, some beats never die.

Ageless beings cling to relics of a distant past, chasing shadows of shelter from the ever-creeping Red Dwarf our Sun has become. Among the cosmos, one substance still sets the universe on fire—Mercury. Mysterious. Musical. Magnetic. Forged only on the last terraforming stations, it fuels immortality for some and endless energy for others. And its power? Transmuted by sound.

Welcome to Fi—a symphony of survival and sound.

Command your vessel as it gallops above a garden orbiting Mars. Build your base—make it a sonic sanctuary or an unbreakable fortress. Grow, gather, or groove at your own pace. Then plug in and amplify—use MIDI inputs to bend the world with your music.

Once your stage is set, dive headfirst into the secrets of the Precursors. Scavenge rare plants and treasure to upgrade your Drum and Bass. Or switch gears—toss your drummer in the backseat and shred across space with Rock and Roll. Whether you're a solo act or leading a Capitol Ship packed with your crew, you'll be blasting away while blasting away.

Fi blends cozy base-building with a beat-driven multiplayer twist. A relaxing jam session with friends—or a full-throttle concert of chaos. With percussion and concussions, it's rhythm meets rebellion.

From Novice to Rockstar, Fi drums up a way for everyone to play—even the most unlikely of bandmates.
