Cortexfall

Master nine turn-based modes, then survive real-time Overrun. Unlock new gear, refine your operative, and conquer the Grid anywhere, completely offline.

Cortexfall is an offline cyberpunk roguelike where every move matters. Descend into procedurally generated sectors, adapt your build to what you find, and fight the machines that seized the heart of the Grid. Nine modes revolve around turn-based tactics. The tenth, Overrun, drops deliberate turns for real-time survival.

PLAN EVERY MOVE

Navigate sectors packed with laser gates, explosive barrels, teleport pads, destructible walls, and ruthless machines. Break enemy line of sight, lure them into hazards, trigger chain explosions, and save your EMP for when things go bad. Four boss archetypes await, each with its own second phase and signature threat.

SHAPE YOUR OPERATIVE

Choose one of four distinct classes. Pick a weapon and an ability before the run, then collect chips, grenades, and augments as you go. Pierce enemy lines with a Railgun, strike from stealth with a Pulse Blade, hack an enemy and turn it against its allies, or deploy a combat drone.
