Ultramodern4 - OGL



Ultramodern4 is presented as an OGL to both support 4th Edition gaming and to reach a larger fan base.  The decision was a difficult one, brought on from conversations with fans regarding the insecurity of the economy.  Simply put, some people didn't want to spend money on something they might hate.  Ultramodern4 is the result of three years of writing, rewriting, and playtesting.  We're proud of the system and believe that so passionately, we're willing to let the product speak for itself.  Even though the OGL does reference maps, these maps are only available in the full edition (as they cost money to make).  We are hoping that this OGL will reach a larger audience which may result in more sales.  If you like what you read, please purchase the PDF or POD, or barring that, send a donation via PAYPAL to  ENJOY.  

NOTE:  This OGL lacks both layout AND artwork.

The mission of U4 is to present 4th EDITION D&D rules for use in non-fantasy settings. These include pre-modern settings, contemporary settings, and those that are far flung fantastic and futuristic. U4 is perfectly suited for any of these following campaigns:

Modern warfare
Space opera
Urban fantasy
Wild west, with or without aliens

U4 has no included setting, allowing you to explore the rules in whatever context you wish. The rules are offered in a general way, not assuming any time period. The equipment lists a wide range of various firearms. Though most are modern, there are quite a few that are retro and futuristic.


  • The new "Ladder" system which offers more adjustability with character creation. Modify your class with one of seven ladders.
  • Eleven new classes including sniper, faceman, infiltrator, and the grappler.
  • New armor including powered combat suits.
  • New skills & feats.
  • All new weapons including traditional firearms, rocket launchers, and laser rifles.
  • Pimp your auto. Purchase vehicles and modify their features.
  • All new opponents from fanatics to tanks.

I don't really know where to get an answer for this. I realized I bought the Ultramodern 4 book several years ago, but never looked through it. A question on armor stats. Armors are listed with a check penalty, which I assume is for skill checks (as in D&D). Unlike D&D, none of the armors were listed with a max dex bonus. Do none of the armors limit your ability to use ranged weapons?

They operate the same as Fantasy armor. In 4th Edition D&D, there is no Max Dex Bonus. You can either add your Int or Dex Bonus to AC with light armor, or you can't with heavy armor.

Thanks for the reply. It's been years since I've played D&D, so I've forgotten a few rules. One other thing I'm having trouble wrapping my head around. How does automatic fire work? I mean, I get that it uses 5 rounds per attack but, is that one hit at the cost of 5 rounds? For example, if I'm playing as a heavy, I can use auto for a ranged basic attack. What's the benefit of doing that, if I only hit once? And what if it's with an attack power with a close blast of 3? Supposedly the target every enemy in the blast, but if it is only 5 bullets, there might be more than 5 enemies in the blast. Sorry for the questions.

From the Book: There are powers with "Auto" keyword. This power can only be used with firearms with the auto or heavy auto property. In addition, with every attack roll, multiple rounds of ammunition are used. A weapon with the auto property fires 5 shots per attack roll while a weapon with the heavy auto property fires 10. Certain feats, features, and powers can reduce or increase these values. When not employing a power with the auto keyword, weapons with the auto property fire only 1 round of ammunition per attack roll with heavy auto weapons still firing 10. Some powers list an entry for auto or heavy auto. If your weapon has the auto or heavy auto property, you can add the auto keyword to the power and gain the additional effects listed in the auto / heavy auto entry. A heavy auto entry requires that the weapon have the heavy auto property, but an auto entry can be used with either an auto weapon or a heavy auto weapon. Applying the auto keyword in this way is optional.

If used with a power such as Potential Push (which specifies the target as one creature), am I getting ten hits with my one attack roll? Or is it one hit, and nine wasted bullets? I guess that's the part I'm getting hung up on. Thanks for being so helpful.

PUBLISHER must detach attack rolls from bullets. An attack roll inflicts damage listed based on the bullets fired. Potential Push, like many other powers, has an additional effect with Heavy Auto, but the bullets are not wasted. Those bullets altogether inflict the power's effect.

Okay, that makes a lot more sense now. Thanks.

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.
