Quarantine Protocol

QUARANTINE PROTOCOL: SITE KILONOVA is a brutal military science fiction campaign for Stars Without Number, combining tactical squad combat, high-tech espionage, cybernetic horror, and impossible choices into an unforgettable mission.

The quarantine failed. The station was abandoned. Something is still waiting.

Eleven years ago, the black-budget research installation known as Site Kilonova vanished from every official record after a catastrophic containment breach. The moon was sealed, erased from navigation charts, and left to die.

Now someone wants to know what really happened.

Your team of elite operatives has been sent on a deniable mission to infiltrate the abandoned installation, uncover the fate of Project MYRMIDON, recover-or destroy-the military AI known as VESSEL, and escape before the station seals itself forever.

Inside the facility, automated defenses still function. Cybernetic horrors stalk the corridors. Survivors cling to life between humanity and machine. Every firefight, failed hack, and wasted minute brings VESSEL closer to complete awareness through an escalating Mission Clock that dynamically changes the adventure as the players push deeper into the station.

Will your squad destroy the AI and everyone connected to it?

Attempt to preserve the consciousness trapped within the machine?

Or become the next additions to its growing network?

Featuring a cinematic blend of military action and science-fiction horror inspired by classics like Aliens, Dead Space, The Thing, and Event Horizon, Quarantine Protocol: Site Kilonova emphasizes tactical decision-making, meaningful player choice, and escalating tension rather than simple dungeon crawling.

Inside you'll find:

• A complete 3-4 session campaign for 4-6 characters
• Multiple mission hooks that fit nearly any Stars Without Number campaign
• Dynamic Mission Clock mechanics that escalate danger naturally
• Multiple factions with conflicting goals and alliances
• Tactical encounters featuring cybernetic Chrysalid enemies
• A memorable recurring villain in the AI Herald Cassia-7
• Five detailed tactical facility maps
• New Strain Exposure rules for contamination and conversion
• Printable player handouts and in-universe documents
• Pregenerated characters ready for immediate play
• Multiple endings with lasting campaign consequences
• Sequel hooks for continuing the story beyond Site Kilonova
• GM quick-reference sheets and streamlined stat summaries

Designed for both experienced Game Masters and newcomers alike, this adventure is easy to run while providing difficult tactical decisions, memorable NPCs, and cinematic action from the opening breach to the final confrontation in the heart of the station.

The quarantine has held for eleven years.

Tonight, someone opens the door.

Will your team save humanity... or redefine it?
