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 am very happy with the Ultramodern4 OGL. Despite some minor typesetting issues and typos (the most notable being "d28" in several places where it should be "2d8", this is a quality product full of useful game info. As far as I [...]

Ultramodern4 is a product for a Wizards of the Coast system that is better than Wizards could have done. Designed for 4th edition D&D, UM4 gives the same (f not better) balance, ease of use, dynamic play, and fun that 4th edition gives, while expan [...]

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.
