The original Ultramodern5 was the most successful non-fantasy ruleset for 5th Edition. This revised sourcebook doubles the content of the original, with revised rules and brand-new mechanics to customize any game.

Ultramodern5 presents races, classes, archetypes, gear, monsters, and scenarios that can be inserted into any campaign. This includes…



Modern Warfare


Space Opera



Wild West

Create a pure science fiction setting or insert any combination of rules into your own fantasy world.

The only limit is your imagination.


  • 10 new races, including aliens, robots, and mutants.
  • A new lifepath system incorporating backgrounds into an adjustable character history.
  • A revised “ladder” system, offering more customization with character creation.
  • 12 new classes, including infiltrator, medic, and sniper.
  • 26 archetypes.
  • Over 130 different firearms from pistols to plasma artillery.
  • Sci-fi inspired melee weapons.
  • New armor (over 40 new options), including exoskeletons and mechs
  • Rules for portable force fields to mimic popular video games.
  • New gear, including cybernetics (30+), vehicles (35+), and aircraft (14).
  • A complete universal giant robot/mecha construction system (25 pages).
  • A techno-magic spell system with enchanted technology, a new class, and a revised spell list.
  • Over 70 monsters, including aliens, robots, and customizable adversaries.
  • New treasure tables, including loot & shoot rules.
  • Six location maps with action scenes to include in any adventure.
  • A spacecraft combat system.
  • A customizable sci-fi dungeon map system with 30 different rooms.
  • Two new adventures—the cyberpunk/superhero Necropolis and the space horror Threshold
The file size listed to the right is not the size of the PDF. When you purchase this product, you'll receive the PDF in standard and low-ink variations as well as hundreds of MB of maps.

Designer Note: This 2nd Edition of Ultramodern5 includes revised rules from the original and adds races, one new ladder, two new classes, many more weapons and armors, revised vehicles, new monsters, and an entirely new set of rules for spellcasting (techno-magic) and mecha construction. Additionally, the two original adventures (Invasion Proxy and Biohazard) have been replaced with two new adventures, Necropolis and Threshold. The original maps have returned along with a brand new set of sci-fi themed dungeon tiles. The page count includes these maps—the content of the game puts the page count at just under 400 pages. The purchase also includes a zipped file of all the maps in high resolution.


Insert any rules from Ultramodern5 into any existing game of any genre, including fantasy!

Hey, I was wondering how balanced ladders are with traditional classes. Say you create a character using your rule set, but pick Barbarian as a class. Would this PC then be balanced against other players who use your book normally?
Customer avatar
Chris D July 20, 2021 3:36 pm UTC
This is a more complicated answer than you may think. We have played with mixed classes; in fact, we do it all the time. And they always appear balanced in our games. However, over the thousands of people playing the game, there have been reports of some classes being more powerful than others, but that's always the case. The same goes with PHB--some classes are more powerful than others depending on environment and level. For example, we introduced two non-combat classes in UM5, the civilian and the face. They are underpowered compared to a barbarian, but that's not the point with them. But we have a martial artist that I think would probably beat a monk in a square fight but the former lacks the innate magical abilities of the latter. The medic is a better healer than the cleric but can't turn undead or smite enemies. There are so many variables to consider, it's difficult to just make a blanket statement of yes. I think they are but it depends on the combination of classes.

I have been looking very hard for a great sci-fi system that is both realistic and keeps rules simple and down to earth for easy learning. Of all my options, this is the system I chose, I love it, but I have one major gripe. The space ships. There is no real formula on how to make your own, at all. It doesn't say which sizes get what rooms, the standard crew per ship size, nothing. All you get is the premade ships for a basis, which are great, except not all sizes are well represented, making it hard to even do it that way.
I love the system, but I am looking for a system for space adventures and a ship is a very important part of that
Also, you have mecha sheets, but no ship sheets. And the rules are not setup to be able to make your own.
Customer avatar
Chris D April 09, 2021 8:17 pm UTC
Thanks for the comments. I have two responses:
Firstly, I added in new mecha and player sheets with the last update. Check your downloads for them. They are not in the PDF for UM5. They are a separate files included in your download.
And unfortunately, I admit not adding in a spaceship construction system but in a pinch, the mecha construction system can be used to make spaceships.
I hope this helps.

Bruce K April 10, 2021 10:26 pm UTC
I know about the sheets for characters and mecha and I appreciate them, I was just saying I didn't see one for spaceships. And I love your system for everything but ships. I will just steal the spaceship system from the Fifth Age system and use your system for everything else. Thank you for being so quick to answering my questions!

The content of the Book Itself is awesome but when my copy arrived the cover fell off. Maybe you lot could look into doing a better job with the glue? $62 bucks for a book. BTW I am not sending it back I did some repairs myself & I don't have time to go threw the whole refund mishigoss.

Anyway apart from that bit as I said the content of the book is awesome which is why I am in a forgiving mood. It contains literally everything you need to make up any genre of Scifi from Hard to Scifi Fantasy and or modern settings. The art is top notice. The drawings and colors really pop (except on the table of contents page. The blue back round set againt the black text doesn't work. Pastels would have been better). I would give it three and a half stars. Four if I leave out the glue problem.


PS would like to see a Threshold Sourcebook in the future.

Firstly, I would recommend, if not implore you, to reach out to DriveThruRPG customer support. Remember, this is a Print-On-Demand service, which means outside of us setting the book to “premium color”, we have no control over quality. Artwork, grammar, layout, that’s us, but print production is entirely the responsibility of DriveThruRPG and their print company. I absolutely do not want you to suffer a damaged book, and they should supply you with a replacement. If not, then I will.

I am overjoyed that you like the book, but I would hate to take a hit on my reputation for an issue falling under someone else’s responsibility.

Also, if you want to see rules that would accent Threshold nicely, check out my Affinity 5E RPG trilogy on Kickstarter now, specifically Conestoga, which has a bunch of rules inspired by Dead Space, which should work perfectly.

Thanks for the kind words.

I have the original UM5, picked it up at retail.
Is there anyplace I can find a breakdown of what was changed/updated/added? (not necessarily the rules around it, just like "added xxx race" "changed xxx rule" kinda thing)
Customer avatar
Chris D April 01, 2021 4:37 pm UTC
I'll try my best to go over changes as there were a bunch:
All the current rules had the errata incorporated into the game.
The "Terminals" setting was added to the intro.
Nine races
One new ladder (performer)
One new class (civilian)
At least 1 new archetype
About a dozen more weapons
A 25 page mecha construction system
A 35 page tech-based spellcasting system
Around 40 new monsters.
Ultramax rules
New loot tables
Two new adventures replacing the two found in the original Ultramodern5.
Oh, and the whole thing is in color now.
Hope that helps!

Hi! I love this book, have read through it many times, used the Gunslinger and Gundancer combo many times and it's been amazing! However, I'm starting to branch out a bit, and I need some clarification. The wording's clear over all, but I tend to overthink some things and get mixed up, especially with new combos.

1. With the Heavy's Attack of Necessity and Rapid Fire talents, do I use the single shot or auto fire damage and ammo consumption?

2. If I go into the Man-At-Arms subclass and make the rifle with the autofire the chosen weapon, do I add the +1 to the saving throws of the talents and/or the burst fire, or just the native single and autofire?
Customer avatar
Chris D March 28, 2021 5:44 pm UTC
1. Generally, when an ability states an auto or auto-heavy weapon is required, you use the auto damage and ammo consumption. This is certainly the case with both Attack of Necessity and Rapid Fire class abilities.
2. Good question on this, technically, it's only for traditional single shot attacks, but I can see it increasing Dex saving throw DCs as well.

File size of the fullcolor pdf is 250mb which means basically that there is room for improvement on the build of the file, I have other full color products filled with beautiful full color artwork that fit under 60mb like for example Exalted 3rd ed which is 650 pages and just a tad over 50mb.

So if you could look into that perhaps to make the file less heavy on the readers and downloading?

As another example of how much the file can be optimized I had one 250 page rpg that in it’s beta face was 115mb but it’s final pdf with all the same art and page backgrounds is only meager 7,6mb file.

We have had professionals and numerous fans attempt to figure out what the issue, and the most they can shave off is a few MB. It's been a conundrum since publication and it appears the only way to address the issue is to build the entire document from the ground's something we have been considering but it is a daunting process. Thank you for you input.

Panu L March 24, 2021 10:30 pm UTC
Sorry to hear that, though you should be rather pleased if the file size is your biggest problem. That is to say the content itself is of excellent quality, though I personally have never cared for the level adjustment mechanic but it is easy to ignore and does not tale anything away from the quality of the product.

Good work overall :)

Chris D March 25, 2021 12:21 am UTC
Yeah, I only opted to use that only when absolutely necessary, like with mecha, where it appeared the only way to balance the power of the mecha to the skill of its pilot. Thanks for the comments.

Hi Chris,

Thanks for continuing to be such an awesome content creator and being of service to us. Will the new books contain more classes and ladders and backgrounds for dark users? will you be releasing a list of antagonists that utilize the Dark magic system? We love the Dark magic system you created.
Customer avatar
Chris D March 15, 2021 4:10 pm UTC
Such a book would be a follow-up to Ultramodern5. Affinity (assuming that's the project you speak of) takes UM5 and builds on it with new ideas. Dark magic is one type of system, Affinity offers two more. The modular weapon construction system is another beefy addition, as is the steampunk weapon and inscription system. Affinity presents more thematically bound ideas rather than UM5's generic approach to rules. In UM5, I built the mechanics without thinking of a setting while in Affinity, the setting was foremost on my mind. Thankfully, the mechanics were written in such a way that they can easily be removed for someone's own setting.

Question about Altered, can you help me understand mutation a bit bitter?

What do you mean by "You can accept
a +1 level adjustment to select two additional mutations"

Thanks again~!
Customer avatar
Chris D March 04, 2021 4:24 am UTC
Level adjustment is a classic mechanic from D&D that is virtually unseen in 5E: Here is the quote from the D&D Wiki:

Certain powerful races start with a racial trait known as level adjustment. Simply put, this is the number of levels you are behind a normal character with the same amount of experience.
For example, a human fighter who gains 3,000 XP reaches third level, becoming a third level fighter. However, a tiefling fighter, who has a level adjustment of +1, only reaches second level at 3,000 XP, becoming a second level fighter.
Assuming the human and his tiefling party member always receive the same amount of XP, they will always level up at the same time, but the tiefling will always be one fighter level behind the human.
In effect, the character starts with one or more blank levels, which give absolutely no abilities (no hit dice, hit points, spells per day, skill points, base attack bonus, etc), except to increase his effective character level for the purposes of...See more

Hey Chris, I love the book you provided. Just some clarification. Does Magus class get assets equal to their vigor plus the class bonus every level? Or do they only get 1 asset every level?
Customer avatar
Chris D February 24, 2021 4:43 pm UTC
It's +1 bonus to your asset, so Asset + vigor modifier.

Are there any custom resources in roll20 for UM5? The character sheet or module on Roll20 would come in handy, as it skews slightly from a traditional 5e.

Roll20 is extremely difficult to reach regarding adapting to UM6 but we are in Fantasy Grounds and D20 Pro. And new custom sheets are coming soon.

Question about Converging Fire

Is the +1 to attack rolls just to hit or is it to damage as well?

Hi all,

What do people recommend as other sci-fi/cyberpunk/futurist 5e resource books? I currently own and backed Redux and use it in a homebrew setting. I want to make sure I am aware of all the resources in this genre that are available. I was suggested GeneFunk as a tool to build-out the biochemical side of the world. One big area of the world I feel is lacking is NPC hackers taking part in encounters. The world is filled with technology and I'm curious to make it relevant and not just scene dressing. I have home-brewed a few hacker NPCs but don't see any examples in books yet. Any books you can recommend or examples you have made and used are greatly appreciated. Even if it's within the genre but not about hacking, I would still be interested.

Well, we have published three setting books using UM5 as a framework. The first predates UM5 and is a sci-fi/fantasy called Amethyst. If you are looking for cybernetics, we have NeuroSpasta, and if you want superheroes, we have Apex. We also got three more settings being published under a single label called Affinity due to hit Kickstarter in a couple months.

Cass G January 14, 2021 5:28 pm UTC
Thank you for the recommendations. I just purchased a hardcover and PDF of NeuroSpasta. It has a lot of what I am looking for. Going to look in the Amethyst after. Super excited for Affinity. Been following it since Redux.

Hello all,

I'm wondering if anyone might offer some advice on a rule here. For the Sniper's Magic Bullet class feature there is some debate in my group (who just started playing) on how this actually works. In fairness all of us in the group can see how the text can be read in different ways, so would like some clarity.
Text text in question is below for reference.

Does the skill cost 1 point for the first use, and then if the target is killed the player spends an additional 1 point and can attack a different target, and may repeat up to 3 times for a total of 3 additional targets each at 1 point for a total of 3 points, or does each use cost one addition point MORE than the prior use, meaning first attack is 1 point, second attack is 2 point, third is 3 (so that 3 attacks would be 1 pt + 2 pts + 3 pts for a total of 6 points.

Would anyone on this thread be able to provide some clarity on this as we would like to play as close as possible to the rules as written...See more
Customer avatar
Chris D January 11, 2021 7:07 pm UTC
The ability always costs 1. You can use it up to three times in one turn. However, you spend the point when you drop a target, not before. Meaning you kill the target, spend 1 point to use magic bullet. Then, if you kill the second creature, spend 1 point to do so again, up to three times.

A fellow DM told me this book has better rules for firearms then the ones I was currently using for my setting, when he showed it to me, I noticed that it said the custom ultramodern classes and the firearms were intertwined in terms of damage output and skills. Does this mean the system would get a bit muddled and firearms wouldn't progress as well if I opt to use the firearms rules but not the custom classes or archetypes?
Customer avatar
Chris D January 09, 2021 6:16 pm UTC
The upscaling of damage output is defined by the classes rather than weapons. This was established in core 5E rules, and we continued that trend with UM5. It would be like a wizard wielding a greatsword. As I don't know the situation with your classes, I can't really comment on how it would work in your game, but that was the design intent. Firearms do the same damage as medieval weapons, and gain increased effectiveness by the class using them, just like Fantasy D&D.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
