"We thought we had it all figured out. We ventured out into the stars with a purpose. We sought to learn, to discover, to make contact with other forms of life. We were the ambassadors of humanity, the trailblazers of a new age of understanding and cooperation.
But we were wrong. We were so very, very wrong.
It started with a few strange signals, some strange readings on our instruments. We thought it was just some glitch, some interference. But then the attacks started. They came out of nowhere, these creatures, these monsters. They swarmed our ships, our stations, our outposts. They killed, they destroyed, they consumed. And we were powerless to stop them.
We lost everything, everything we had built, everything we had fought for. Our homes, our families, our friends. We were the lucky ones, the ones who managed to escape. But we were left with nothing, nothing but our skills, our training, and our determination.
So now we do what we do best. We explore the galaxy, but not for knowledge, not for diplomacy. We are in search of resources, technologies and opportunities. We delve into the derelict ships, the abandoned stations, the ruins of our peaceful missions. We scavenge for supplies, we salvage for weapons and riches, and we hunt for the monsters that destroyed the hopes of a better world.
We are the Derelict Delvers, the last hope of humanity. And we will not rest until every last one of those creatures is dead and every opportunity is seized"

What is this game?

Derelict Delvers is a thrilling, action-packed sci-fi roleplaying game that immerses players in a struggle for survival and profit. The game takes place in a galaxy overrun by monstrous alien creatures, who have destroyed humanity's peaceful exploration and diplomatic efforts.

The players take on the roles of elite space troopers, scientists, and engineers who must explore derelict spaceships and space stations in order to scavenge for supplies, salvage for weapons and valuable resources, and ultimately, hunt down the monsters that threaten the very existence of mankind. They are a team of skilled specialists, who are on a mission to help humanity, but also themselves.

With a unique blend of fast-paced combat and challenging perils, players will have to work together (or alone!) to overcome the dangers of the derelict ships and outsmart the deadly aliens lurking within. They will also have to make difficult decisions that will affect the outcome of their missions, their potential profits, and their very survival.

Derelict Delvers is a journey of exploration, of discovery, and of opportunity. Join the elite team of Derelict Delvers, and see how far you can go after the fortune the galaxy has to offer.

I have a question. The character sheets have spaces for up to three "Additional Powers". 
The only advancement rules I can find is the one sentence "Everything you salvaged during your mission can now be traded for repairs and upgrades or even new weapons, gadgets and abilities."
I assume this is not just exchanging Loot Tokens but also based on the value of the captured derelict or successful mission objectives in the story. 
Does anyone have any guidelines for what kind of rate of advancement is suitable? I assume you don't just hand over a d8 Loot Token after the mission for a new special ability.

Hey, there! Thanks for your quesiton!

Advancement is taken care by the FIX CHECK, on page 29. It goes like this: 

You may spend any amount of LOOT dice you have to enhance your Powers or get new ones. If you do so, erase those LOOT dice, roll them together, and add up all results you rolled. These are your Fix Points (FP).  Spend them as follows, in any combination you want.

  • 2 FP: Cool down 1 Heat on any of your Powers (including OVERHEATED ones) 
  • 4 FP: Add 1 Boost to any of your Powers 
  • 8 FP: Create a new Power

any chance of a couple of community copies being added? Id happily write a review for the game. All good if youre not though

I've missed this comment somehow, but there are some more community copies up, I hope you're able to grab one!


Would love to talk to you about a review copy, as I would love to make this the space addition to my next episode.

Yup! Shoot me an email (it's on my website) and we can work something out


How printable is the pdf? Shipping from lulu is pricey where I live so even with the PoD coupon I'd like to print it off myself, but it looks to have a lot of black that would use tons of ink.


The darker pages are the chapter titles only. All text is on white background. I’ve seen some people printing a negative version of the title pages, but they aren’t really necessary, if you don’t mind them. In short, I believe it’s mostly printer friendly :)


I lie! The table pages have darker border too. But the reference guide that also contains all the tables is on full white background 


I watched a playthrough and I think I can get by with only printing the reference guide. Thanks for the prompt info!


Super cool, and easy to learn RPG.

I played it on the "Giant Book of Sci-Fi Battle Mats," used two 28mm Space Marine miniatures, along with a few 32mm Sci-Fi miniature monsters, and I stayed entertained for quite a few hours. Totally fun...especially on solo-mode. Good job!

Oh, that’s superb! I’m dying to play it with minis myself. Thanks for the feedback! ^^


I recently did a solo playtrhough (along with a rules overview) of this on my channel and had a ton of fun! This game has a lot of cool/unique concepts and I like how creative it lets you be with the character concepts, powers, dangers, ect. I'll definitely be playing more in the future. Hopefully I didn't get any rules too wrong:


This is fantastic, Thomas! Thank you so much for sharing, can’t wait to watch it ^^


This is an excellent GM-less game; it feels very freeing, and the meta-roles (and the way that hazards *react* to player attacks to both deal and take damage) mean that the players don't flounder waiting for someone to take initiative to move the action along.

However, I wish it had just like, a spoonful less crunch - I don't like the Target Number table for the Flair checks/powers, it seems like a very numerical spreadsheet part of the game where other things feel much simpler (roll some dice, see what lands 5+.) It also seems like Boons and Loot could be combined to simplify things, but talking this over with some friends, I understand why they're separate - but it feels like some stuff could be stripped down to make this just a little leaner and simpler to play.


Thank you for checking out the game and for the feedback! Always appreciated 


For what it worths, I really appreciated the power effects table. Sure, it seems "crunchy" at first, but in the end it's a really good way to create on the fly lot of cool mechanical effects in game. Aaaand, it's super easy to remember, because it's very uniform way (it's just counting "1, 2, 3..." for every aspect you want to gain).
Probably there was no other way to obtain all those effects in an easier way.


Thank you, Andrea! Yes, I tried to aim to that consistency so that after a few times, you could do it easily. I’m glad you enjoyed it!


Now also findable on GoodReads!!


Thank you so much, that's very cool!
