Siren’s Call: Interstellar Colonization Roleplaying

$12,548

Humanity's first step beyond the Sol system might be its last.

Siren's Call is a campaign and sourcebook for the Shadows Over Sol roleplaying game. It follows the story of the ARC Project, humanity's first ever attempt to build and launch an interstellar colony ship.

The ARC Project is one of the most ambitious endeavors ever undertaken. If successful, it will transport some 10,000 colonists the 4.4 light years from Sol to the planet Siren, orbiting Alpha Centauri A.

The journey will take 400 years, with all passengers and crew in stasis. No one knows exactly what will be found on the other side — what challenges and horrors the colonists will face as they make a life on this new world.

Siren's Call is inspired by a variety of science fiction media, ranging from Sid Meier's Alpha Centauri and James S. A. Corey’s excellent The Expanse series, to Ridley Scott’s classic film Alien and Kim Stanley Robinson's Mars trilogy.

The Siren's Call campaign and sourcebook will be a full-color hardback volume estimated at 240 pages. It includes:

  • A flexible campaign consisting of eight core scenarios, plus numerous optional "side trek" adventures and ample room for GM-created personal plots.
  • Complete details on the ARC Project and the Alpha Centauri system, with plenty of insight and plot hooks for other interstellar colonization adventures.
  • Descriptions, ecological details and stat blocks for numerous exoplanetary lifeforms, enigmatic machines, human archetypes and individual characters.
  • A new system for colony building, societal planning, advancement and mass combat. What type of society will you create?
  • Optional rules for character aging, as well as how to handle wealth and lifestyle in the colony.
  • New interstellar colonization-related gear, vehicles and genelines!

“Great setting with a ton of awesome info and backstory and cool art...”
—Jack M., DriveThruRPG

Two hundred years from now what should be the shining beacon of the future is instead cloaked in conspiracy and horror. Humankind has expanded throughout the solar system, and there it has discovered mysteries older than humanity.

The culture has shattered into myriad subcultures; nation-states are the hollow shells of what they once were. Corporations and other groups wage small-scale wars in the streets or in space. Bioengineered horrors left over from these conflicts stalk the hulls of ruined stations and abandoned colonies.

But for an enterprising team willing to brave the horrors, there's always a profit to be made.

The Shadows Over Sol core rulebook was first published in 2016. Since then, seven adventures, three supplements and four accessories have been published for the game line. Siren's Call will be the largest and most ambitious to date!

Once the initial funding goal has been reached, additional stretch goals will be unveiled. These goals may either be unlocked at specified funding levels, or at a specific number of patrons for Tab Creations' accompanying Patreon project. The conditions for unlocking each goal will be specified in its description.

UNLOCKED! - Siren Poster Map - $2000: Our first stretch goal unlocks a world map of Siren, the planet to be colonized by the ARC Project. This will be made available in print as a poster map, and digitally in a high resolution image format. The electronic version and an "at cost" code for the print version will be included in all reward tiers at THE GAME and up.

UNLOCKED! - Player's Brief - $3000: The Siren's Call Player's Brief will be a full color PDF document containing all of the player-facing information and options from the Siren's Call campaign and sourcebook. Perfect for GMs to distribute to their players before the game! It will be included in all reward tiers at THE GAME and up.

UNLOCKED! - Colony Ship Deck Plans - $4000: This stretch goal unlocks a set of deck plans for the ARC Project colony ship. These will be made available in print as a poster map, and digitally in a high resolution image format. The electronic version and an "at cost" code for the print version will be included in all reward tiers at THE GAME and up.

UNLOCKED! - Product Upgrades - $5000: When this funding total is reached we will upgrade a number of Shadows Over Sol products to include the latest production options and information from Siren's Call. This includes adding a GM Screen Insert for the new Colony Building system, updating the Roll20 character sheet and revising the Quick-Start to include better art and an upgraded layout.

UNLOCKED! - Double the Art Budget - $6000: At this funding level we can afford to double the budget the game has for art and layout, making the final sourcebook better for everyone!

UNLOCKED! - Additional Scenario - $7000: When this funding total is reached we will add an additional scenario to the Siren's Call sourcebook, further expanding the adventure possibilities for everyone! This scenario will be one of the many optional "side treks."

UNLOCKED! - Prelude Adventure - 25 Patrons: Tab Creations has a Patreon where every three months we release an adventure or other short supplement. If we can increase our Patreon to 25 patrons by April 26, we will release a prelude adventure to Siren's Call free to all patrons and backers of this Kickstarter!

UNLOCKED! - Pregenerated Colonists - $8000: At this funding level we will publish a set of pregenerated colonists, ready to use as player characters or as NPCs in your Siren's Call campaign. These will be released in PDF with ready-to-print character sheets, and will be available to all backers.

“Love the Saga Machine system... Going to adapt the system to other RPGs!”
—James C., DriveThruRPG

Siren's Call for Shadows Over Sol combines the wonder and mystery of science fiction with the intensity and danger of the horror genre. The core system, Saga Machine, has been in use for a decade, including publication in our other roleplaying games, Against the Dark Yogi and Dime Adventures. This version of the rules was published in 2016 and has received widespread praise. We have 4.9/5 stars on DriveThruRPG!

Gameplay highlights from the core rulebook include:

  • Support for a wide range of science fiction themes and tones.
  • Campaign options specifically designed to adapt to different levels of horror. Easily dial your game down to survival horror or up to action horror!
  • An engineering system for inventing or improving upon existing technology.
  • A hacking system designed to engage all members of the party. No longer are the rest of your players going to sit and wait for one player to finish the hacking minigame!
  • A combat system designed for tense and deadly confrontations.
  • A wide selection of gear and bioengineered monstrosities to terrify your players!

All backers can access the complete draft text of Siren's Call today! Simply follow the link from the first backer-only update!

Siren's Call has been in development in some form since the release of the Shadows Over Sol core rulebook in 2016. The concept has gone through multiple iterations and the campaign has received three rounds of playtests. The text has been written, we have some great art in the works and we can't wait to share this project with the world!

Shadows Over Sol has seen development and play as a homebrew setting since 2009, and this incarnation of the rules is the result of over two years of development and public playtests.

As with our previous projects, we will again be Kicking it Forward!
