Play Sonic Epoch Online

Sonic Epoch was a Game Boy Advance title that never saw an official release, leaving it as a piece of unfinished, playable media for those who seek it out. It was developed by an uncredited team, surfacing during the GBA's lifespan when fan projects and ambitious, unofficial Sonic titles occasionally captured attention. It exists in that curious space between prototype and passion project, a snapshot of what might have been on a handheld known for its robust library of platformers.

You control Sonic through a series of time-displaced levels, each demanding precise jumps and quick reactions to avoid pitfalls and enemies. The main goal is simply to reach the end of each stage while gathering rings and defeating robots, but the level design introduces shifting time periods that alter the environment mid-run. One moment you're bouncing off springs in a lush prehistoric jungle; the next, the screen glitches and you're threading through narrow corridors in a stark metallic future. The pace is relentless, and some sections are unforgiving, requiring memorization and tight control. It feels like navigating a fractured, high-speed obstacle course where every screen demands your full attention.
