If that sentence alone makes you grin, then let me introduce (or reintroduce) you to one of my favourite 5e settings: Dark Matter by Mage Hand Press.
Dark Matter isn’t just “D&D with laser guns taped on.” It’s a fully realised sci-fi expansion for Dungeons & Dragons that reimagines the system on a galactic scale—without losing the soul of what makes 5e feel like home.
Let’s talk about why you should be playing it.
(If you prepare to watch rather than read then please watch below)
What Is Dark Matter?
Dark Matter is a 5e expansion set in a universe known as the ‘Verse. In this setting, spaceships travel light-years in the blink of an eye using Dark Matter engines. These engines shrink ships and their contents down to an infinitesimal size and sling them through a dangerous Void dimension.
The Void is not safe.
It’s irradiated, unstable, and deadly without proper preparation. Pilots rely on star charts, Astrogation magic, Maw stations built around the skeletons of ancient star-beings, or even psychic insectoid “roaches” that induce hallucinations to judge the length of a Void jump safely.
Yes. That’s the tone.
Technology and magic have evolved together to the point where they are practically indistinguishable. Arcane blasters, universal translators, datapads, comm sets, and life suits aren’t technological replacements for magic, they’re magical evolutions of it.
Your communicator? That’s just an advanced Sending stone.
Your universal translator? Permanent Comprehend Languages.
Your hoverboard? A levitation spell powered by an arcane battery.
Magic isn’t side-lined. It’s integrated.
The Tone: Everything, Everywhere, All at Once (In Space)
Dark Matter proudly wears its influences on its sleeve. You’ll see shades of:
Star Wars
The Hitchhiker's Guide to the Galaxy
Alien
Blade Runner
Guardians of the Galaxy
Mass Effect
Dune
Warhammer 40,000
And somehow, it works.
You can lean into space opera heroics, corporate dystopia, cosmic horror, pulpy adventure, or absurd sci-fi comedy. The setting gives you room (yes, space) to shift tone as needed.
Unlike some sci-fi adaptations, Dark Matter doesn’t feel like homework. It feels like D&D—but bigger.
Sci-Fi Without Losing the Soul of D&D
If your table is hesitant about sci-fi RPGs, Dark Matter is the perfect gateway. Players don’t need to learn a new system. Everything familiar about 5e is still there, just reconceptualised.
Comparing it to Spelljammer, which feels like fantasy ships sailing through space. Dark Matter, by contrast, is full science fiction: lasers, power armour, cybernetics, Void travel, and high-tech infrastructure.
And it’s thought through.
Take energy weapons. Laser blasters often roll higher damage dice—but you don’t add your ability modifier to the damage. That keeps traditional weapons relevant and avoids everyone defaulting to “laser everything.”
Skills are adapted for sci-fi contexts, with additions like Data, Technology, and Piloting. Magic users remain powerful and relevant, with themed spells and mechanical integrations that make sense in the setting.
This isn’t duct-taped sci-fi. It’s engineered.
The ‘Verse Feels Vast (Because It Is)
The lore is deep without being suffocating.
The ‘Verse is mapped just enough to give DMs structure while leaving plenty of unknowns to explore. Factions, corporations, cabals, religions, cults, and colonial powers all have clear motivations.
Fantasy archetypes still exist, but in space:
Dwarves are still stubborn and stalwart, just asteroid miners.
Elves are still elegant and long-lived, just among the stars.
Orcs? Still strong, just better with a plasma wrench.
But Dark Matter goes further with original species:
Star-worshipping Avia-Ra with militarised religion
Amoeboid beings staffing mysterious Maw stations
Nautilids in water-filled suits searching for a new home
Skathari insectoids bound into servitude
Vect constructs from enigmatic Foundry ships
Wrothians, psionic aliens doomed to exile if separated from their brood
Add Dead Magic Zones, robot-zombie N-virus outbreaks, extreme-gravity planets, ghost ships, abandoned stations, and cosmic horrors—and you have an endless playground of adventure hooks.
Spaceships That Don’t Hijack the Game
This is huge.
Ship combat in many systems feels like a mini-game that side-lines half the party. Dark Matter avoids that completely.
Ships are party assets with their own character sheets. Everyone has a role:
Engineers reroute power to shields, weapons, or engines
Gunners apply proficiency and feats to ship weapons
Pilots manoeuvre
Spellcasters can channel spells into ship systems
Fighter pilots launch dogfighters
Combat scales naturally thanks to Mega Damage, separating personal combat from ship-scale destruction. You’re not pausing the campaign to play a spaceship board game—you’re extending your characters’ abilities into space.
It’s clean, intuitive, and dramatic.
Character Options Galore
Dark Matter explodes with options.
New ancestries.
Sci-fi themed backgrounds.
Tech-infused subclasses.
Psionics, cybernetics, Void magic.
Hacker Rogues.
Engineer Wizards.
Clerics devoted to living star gods.
There’s even a new class: the Gadgeteer, distinct enough from the Artificer to justify its place.
Some options are delightfully on-the-nose (yes, there’s essentially a Space Marine archetype), but they’re executed with care and fun in mind. And honestly—if it wasn’t there, you’d be asking where it was.
It’s a lot of choice. For some, that’s intimidating. For me? It’s a playground.
It Fixes High-Level D&D (For Me)
High-level 5e characters are practically gods. In a traditional fantasy setting, that can feel cramped.
Space solves that.
Stakes can scale naturally:
Ship → Station → City → Planet → Star System → Empire → Galaxy → Multiverse.
Your level 17 wizard suddenly feels appropriately scaled in a universe filled with cosmic threats.
It gives serious Star-Lord energy; going from petty heists to reality-shaking battles without feeling disconnected.
Final Thoughts
Dark Matter feels designed with modern 5e philosophy in mind. Clean subclass identities. Clear roles. Strong thematic cohesion. It works with everything you already love about D&D, but expands it.
While there are incredible dedicated sci-fi RPGs out there, Star Wars Roleplaying Game, Alien RPG, Mothership, Dark Matter offers something unique:
You don’t have to leave D&D behind to explore space.
If you want to play out your Mass Effect, Guardians of the Galaxy, or Star Wars fantasies while staying in the mechanical comfort of 5e, Dark Matter is one of the best gateways available.
So if you’re ready to take your campaign beyond the atmosphere and into the Void—
Why not play Dark Matter?
