Dark Conspiracy the RPG

Dark Conspiracy is live on BackerKit

* Sorry for the delay in getting this posted, focus has been on tidying up the site prior to my hosting shift*

After a relatively short development period, Mongoose Publishing has begun funding for Dark Conspiracy:The Unseen War on BackerKit.

At the time of writing, the crowdfunding has raised £103,367 against a goal £20,000 after just a few days.

What is Dark Conspiracy: The Unseen War?

Dark Conspiracy is a horror roleplaying game set in our own modern world – or just a few years hence. A terrible threat lurks in the shadows, one utterly unknown by most of humanity. If the world is to be kept safe, this ignorance has to be maintained. A conspiracy of secrecy, ignorance and darkness must be constructed for the greater good of all.

The danger is real. Merciless creatures from dimensions beyond comprehension press against the veil that separates worlds. Their motives are unknown, but it is clear that they delight in suffering, chaos and pain. In the past, they have gone by many names; ghosts, bogeymen, supernatural phenomena, and cryptids of all shapes and sizes.

Dark Minions are so much more than that.

It’s just over a year since darkconspiracytherpg last spoke to the team over at Mongoose Publishing. With development moving at pace, we thought it was time to catch-up once more, this time looking at progress, plans and the upcoming crowdfund campaign for Dark Conspiracy: The Unseen War.

Update on Mongoose’s Dark Conspiracy

More information on the new Dark Conspiracy is now up on Mongoose Publishing’s website.

To be released as Dark Conspiracy: The Unseen War, it is quote “a modern-day horror RPG that will see your players take on the role of Operatives, handpicked by a mysterious organisation to defend the Earth from the deepest terrors beyond imagination”.

The press release details the Tone of this new edition, and highlights the move to the Traveller-engine ruleset. In addition, the new game will include:

All new careers to create your crack team of chosen Operatives.
Tracking the level of Trust the organisation has in you and your team.
The presence of Empathic powers which have just started to be found amongst humans – though no one really knows where they have come from or why.
The construction of the Operative’s own cell, the resources it has access to, and its own (fully customisable) headquarters.
The nature of missions the Operatives will be undertaking, and why maintaining the conspiracy is more important than data-gathering or neutralising Dark Minions.
The use of cults dedicated (knowingly or otherwise) to the Dark Minions, and mechanics to represent the reach of their grasp in the world.
We have also included a system so Operatives (your players!) can create their own conspiracy, nursing it throughout a campaign by investigation, to present to the Referee – who will be able to create a brand new mission (or more) to determine whether they were absolutely right… or complete crackpots.

To keep up-to-date with the development of the game and its setting you can also follow along with the Developer’s Diary on the Mongoose Forums.

With the recent acquisition of the Dark Conspiracy property by Mongoose Publishing (https://www.mongoosepublishing.com/collections/dark-conspiracy-of-the-past), enquiring minds were keen to know what the new owner’s plans might be for the venerable Tabletop Roleplaying game. Matt Sprange (Head Mongoose) has graciously taken the time to chat with me to answer some of those burning questions.

A little late to the party, but Mongoose Publishing recently announced that they have acquired the Dark Conspiracy property (to go along with their previous purchase of the Traveller IP).

Looking forward to seeing where this new reimagining of our favourite Roleplaying game might go, with news that a new edition (utilising the Traveller mechanics) will likely see light of day sometime in 2026.

Here’s the full press release as posted on Facebook –

Last week Mongoose Publishing acquired all rights to the Dark Conspiracy RPG, the classic game pitting players against an ancient and alien horror.

There will be a lot more news in due course, but we are delighted to say that Dark Conspiracy slides right into a project we have been working on and off for nearly two decades – indeed, it will be the final component needed to bring everything together. Expect to see a brand new Dark Conspiracy in 2026.

In the meantime, you can find the original Dark Conspiracy PDF titles on our website – https://www.mongoosepublishing.com/collections/dark-conspiracy-of-the-past
