What is this system

The cyberpunk spiritual successor to MÖRK BORG — same furious art-punk DNA, same brutal lethality, now drowning in neon death smog. CY_BORG takes everything Mörk Borg perfected and smashes it through a chrome-plated, corpo-owned meat grinder. You will probably die. The city doesn't care. The ads keep playing regardless.

Setting

Megacity Cy, year 20X3. The Incident happened and things have only gotten worse since. Fourteen megacorps own the sky, the ground, and everything between. Slums rot beneath scraper-forests of towers. Neon cathedrals advertise products your character can't afford. Bacteria from outer space have hijacked human nanorobotics and nobody has a fix. The apocalypse is tracked in Miserable Headlines — seven headlines, each worse than the last, and when the seventh drops, the city's data is purged. The world is always ending. It just hasn't finished yet.

What it looks like at the table
The feed pings: Miserable Headline #4 — 'Nano-plague outbreak in Sector 9. Quarantine drones deployed.' Your Burned Hacker jacks into a corpo terminal, rolls Knowledge against 14. Fails. Security ICE hits back: d6 damage to your already-scarred body. The Forsaken Gang-Goon kicks the door in anyway — Presence check to intimidate the suit at the desk. Rolls a 3. The suit smiles. Somewhere above, a drone launcher tracks your biomarkers. Your nano powers twitch. Something is living inside you and it wants out.

Key mechanics

Miserable Headlines

A d66 table of cascading disasters plays out across the campaign. Seven headlines = the city dies. Sessions tick toward an inevitable, spectacular end.

Nano Powers

Alien bacteria hijacking your body grant horrifying abilities — repair tissue, consume matter, steal a corpse's last memories. Powerful, uncontrollable, and always hungry.

Cybertech & Six Classes

Six classes for your class war: Burned Hacker, Shunned Nanomancer, Renegade Cyberslasher, Forsaken Gang-Goon, Discharged Corp Killer, Orphaned Gear Head. Each pre-loaded with trauma, debt, and a very specific way to die.

Fast & Lethal d20

Roll d20 + stat modifier, beat a target number. Stats range from -3 to +3. Optional tactical crunch adds cover and suppressive fire without bloating the core.

What people say
Whether you've got an unstoppable killer or a frail gearhead, you'll have a blast running them face first into the meat grinder of Cy. The city wants you dead, and that makes it irresistible.— Bloody Disgusting review
Whereas I wouldn't run Mork Borg as anything but a one-off, Cy_Borg holds up to long-form play. The setting is thin enough that you fill it with your own neon-soaked paranoia.— TTRPG Factory, ttrpgfactory.com
