Broken Codex

Run the rooftops. Break through the network.

Security machines are turning on the people they were built to protect. As an Overseer, you're sent to investigate

Broken Codex is a neon action-platformer demo. Double-jump across the city, blast through hostile machines, and slam down with a Down Spike. Between runs, return to your safehouse, spend Data Credits, and build a loadout for the next fight.

Inside the demo

• Three story chapters: follow the disturbance from city rooftops into an old server archive and a neglected neighborhood.
• Three boss battles: read attack warnings, stay moving, and fight through changing phases.
• Choose your Overseer: start with Vex, Kaito, Rocco, Vibe, or Shade, each with their own look and dialogue. Finish Chapter 3 to unlock a sixth character.
• Build your loadout: equip weapons, damage chips, armor, mobility upgrades, and tactical implants.
• Keep running: chase your best score in Infinite Mode

Broken Codex is still growing, and I’d love your feedback—especially on upgrades and the features you want to see next.

• Upgrades and progression: Which upgrades feel useful, underwhelming, or missing? Do the prices and power levels feel right? What would make building your loadout more fun?
• Character-specific abilities: Should each Overseer have a unique ability or playstyle? What abilities would you like to try?
• Future features and polish: What would keep you coming back? Share your ideas for new features, plus anything that feels confusing, frustrating, or could use improvement.
