2670 rules expansions
This section contains optional rule expansions for the core 2670 system. They are designed to extend, not replace, the main rules — adding new layers where they matter most in play.
Here you will find additional character professions, ready-to-use NPCs, and other modular elements that allow you to tailor the system to the tone, scale, and focus of your campaign. Each expansion is written to remain mechanically consistent with the core rules while opening new narrative and tactical possibilities.
These materials are meant to be practical and flexible. You can introduce them selectively, combine them freely, or use them as inspiration for your own modifications. Together, they expand the toolbox of 2670, giving you more ways to explore its universe without losing its grounded, hard sci-fi character.
Characters Portfolio
Above is a collection of ready-to-use characters you can drop straight into your 2670 RPG games. Each one is reasonably built, comes with rolled attributes, and carries practical, no-nonsense gear. They work perfectly as player characters for one-shot adventures and are always within reach whenever the Overmind needs an NPC on the fly.
A note on design: these characters are not strict representations of the Basic professions. They can have some unusual skills, personalised tweaks or slightly unorthodox equipment – all by design. Their purpose is to deliver fun gameplay out of the box, support different playstyles and form distinctive, memorable teams. For this reason, their listed professions don’t match the Basic professions (or any other official lists).
Set 1 contains 12 characters roughly equivalent in power to starting or undeveloped PCs, making them an excellent fit for 2670 Shorts adventures.
Corporate professions
Corporate safety. Ethical progress. Sustainable exploitation.
The 2670 – Corporate Professions supplement introduces six thrilling new ways to sell your soul — legally!
Whether you’re suppressing dissent, sanitizing data breaches, or “encouraging team harmony,” you’ll find the perfect role to advance both your career and your employer’s moral bankruptcy.
Benefits include: risk, distrust, and a monthly salary indexed to your expendability.
Space Crew Professions
Vacuum-rated loyalty. Improvised survival. Shared guilt.
The 2670 – Space Crew Professions supplement introduces six roles for those who keep flying long after it stopped making sense.
You’ll patch hulls, reroute power, negotiate with gravity, and discover that space doesn’t care about your backstory.
