Dias Ex Machine, creators of Amethyst, have announced the upcoming release of Ultramodern4. UM4 brings non-fantasy rules to Dungeons & Dragons 4th Edition. It will include new races, skill, feats, weapons, transportation, armor, and a new system for creating characters.

On it’s own it sounds pretty cool, but the best part is what I’m about to tell you. UM4 will be released under an Open Gaming Licence. They’re going to offer the barebones rules as a free download and hope that you’ll like it so much that you’ll buy the full product that contains all the artwork and a better layout.

UM4 should be released this winter in PDF and Print-on-Demand form. The OGL files are expected to be released for download around 2 weeks after the initial launch.
