Dias Ex Machina to release APEX, Ultramodern4 superhero "DLC".

DEM, publishers of Amethyst and Ultramodern4 will be releasing a supplement for its popular Ultramodern4 4th Edition ruleset. Apex introduces mechanics for superheroes and paranormal abilities in urban and science fiction settings. 

Apex is inspired by modern superhero tales—where enhanced humans hide from forces wishing their eradication. Readers will find similar philosophical similarities between Apex and Amethyst, as both are constructed from similar DNA. Expect Apex's release sometime in the spring.

Also recently announced is that if DiasExMachina's FB page reaches 150 likes, then anyone that has the POD or PDF of Ultramodern4 (not the OGL) will get Apex for free. Apex is expected late Spring

July24th, 2012
Today, marks the opening of DEM's Merchandise Store, care of Cafe Press. We're offering dozens of products utilizing logos and artwork from DEM products. All artwork by Nick Greenwood

A bunch of Ultramodern4 reviews...
Roleplayers Chronicle (Todd Crapper): "Ultramodern4 is a magnificent accomplishment in alternative game design and I can’t help but feel it is superior to D&D, even if it is required to play this game. It achieves what D&D could not because it was not held down to a particular reference point – previous versions of D&D – and capable of stretching its reach far beyond what many experienced players may have expected of these troubled mechanics. I only hope the GSL does not make this product a limited edition."

Solo Nexus: "Be warned! Ultramodern4  IS a “crunchy” book, although it is by no means a technical manual. Still, this is a product for those who WANT to take a very radical departure with their 4E game. Do not get this if you’re mildly curious about what a Dwarf Barbarian would be like armed with a rotary cannon. Get this if you truly want to bring modern and futuristic combat to life with the 4E system."

Points of Light: "This book feels like a good spiritual successor to 3rd Edition's D20 Modern. The lack of an implied setting or time period, coupled with the fact that you can mix and match content from either book makes it easy to do an Urban Arcana game, and I could see rolling in Gamma World to get something a lot meatier if that is your thing. Heck, why not lump it all together and have your very own 2nd Edition of Rifts, if even by name only?

RPGNow: "Overall I have to give this product a thumbs up, its quality is not only in its content but its layout as well, I personally have not had many 4e 3rd party products with the production quality that DEM puts in its products."

May 10th, 2012
Ultramodern4 is now available.

May 7th, 2012
...And it's ready...
Ultramodern4 will be released on Thursday, May 10th.
Anyone running a blog or a gaming website that wishes to write a review for Ultramodern4 should send me a message (with the website address) so I can ensure they receive their copy.

March 28th, 2012
We have two free previews for Ultramodern4: the first six pages and the hot sheet--which lists damage types, basic attacks, and keywords.

March 22, 2012
Little fanfare...no huge banners...
Ultramodern4 will be released in April
Amethyst - Renaissance will be released in May.
...with hope...fingers crossed...

January 13th, 2012
Anyone that has been tracking the progress of Ultramodern on our facebook page knows that we have an official logo and some artwork finally posted. The announcement of 5th Edtion D&D has really accelerated the progress of this work.

October 14th, 2011
As some of you've figured out by reading Amethyst's facebook page or reading the articles on LivingDice.com, we recently made a relatively big announcement.

Ultramodern4, our universal 4th Edition science fiction / modern game system will be offered as an OGL. Anyone will be able to download the bare files for free. Any publisher under the GSL can use them in their own game. We will not be distributing the final production for free, just the raw rules. So if you want the layout and the art, we hope you'll pick up the final product.

July 22nd, 2010
In order help ease people into the new Amethyst errata, Chris and Conan sat down with the file along with the FAQ an explained it all in this helpful PODCAST. We are as civilized as always. Along with answering questions, we also supply a few extra rules not offered in the errata that go into our personal game.

July 14th, 2010
Goodman Games and Dias Ex Machina are now presenting the Amethyst Errata. Although many of its points are from concerns we had late in the game’s development, the vast majority came as a result from buyer feedback. It may not be the last but we feel comfortable this covers the vast majority of issues. The errata contains corrections, modifications, and additional rules to improve game balance.

June 18th, 2010
Two points today:

1) Kobold Quarterly has posted a review of Amethyst Foundations.

2) The public has demanded and we have answered. You can now download the Amethyst Character Sheet. It has editable field codes.

There is a particularly positive review over at Lost Cause I want to share..

January 19th, 2010
As promised, this week marks the release of the Biohazard Playtest Module, showing off the current edition of Amethyst's science fiction rules.

January 18th, 2010
Our friends at Neuroglyph Games have posted a review for our upcomming Biohazard module.

January 14th, 2010
Yes, it is true. We are NOW taking pre-orders for Amethyst to be released in April. Well, rather Goodman Games is taking the pre-orders for Amethyst. I urge everyone that has followed us since the early days to show your support and place your pre-order. It will gauge the print-run, the speed of follow-up products, and the like.

January 12th, 2010
Here is a link I wish to share. There is a Freezine podcast, CALive, over at Emerald Press. At the end is an interesting announcement.

January 8th, 2010

We should be adding another part of our series of video commentaries every four days or so. Check the downloads page or follow the videos to their YouTube page to see them all.

January 4th, 2010

DEM will be starting a series of video commentaries dealing with the development of its artwork. Both myself and Nick Greenwood contributed to the video. No, you won't be seeing us. Instead, you will see some of Amethyst's best artwork from early sketches to their final forms. There are dozens of pieces never before seen.

December 3rd, 2009
What we have here is the first official piece of artwork for NeuroSpasta, thanks to our favorite neighborhood artist, Nick Greenwood.

October 24th, 2009
I know that this is not releated to DEM, but I (Chris) has his name on a pair of Goodman Games products coming out soon, From Here to There and Azagar’s Book of Rituals.

By popular demand, we have recut all four techan podcasts into a single Best Of Podcast with all the funniest moments cut into a single file. Hope you all enjoy it.

December 12th, 2008
a FOURTH techan podcast. This one is the longest but by far the most entertaining. The players come across their greatest threat yet and I do everything in my power to kill them.

November 22nd, 2008
Techan Podcast, Part 3 is now online, where our valiant heroes dive into the deeper levels of Punjar. They go up against slavers, an oddly placed gorilla, and defend against the advances of amorous goblins.

November 9th, 2008
Techan Podcast, Part 2, where our techan heroes conclude their battle with the bums, grubbs, and senile otyugh. After its conclusion, listen to the extents the players will go to acquire treasure. I won't ruin the surprise but it does involve a flashlight and a human suppository...

October 29th, 2008
Techan Podcast. Okay, here's the deal: The guys and I sat down with Goodman's Sellswords of Punjar adventure but played the dungeon crawl with 4 techan classes. The first podcast got lost so this one recaps the first session and dives right into combat. Listen as four rifle/pistol/pipewrench weilding techans wade through the slums of the city's underground, battle accountants and theives, and somehow redirect an Otyugh into fighting on their side. This is a three part podcast.

October 19th, 2008
As everyone now knows, we have formed an alliance with Goodman Games to release Amethyst: Foundation. Check out the Press Release. The game is due out in digital in April and print in August.

A new PODCAST talks in detail of the agreenment and what this means for the company

June 24th, 2008
Amethyst is moving to D&D 4th Edition. Updates to follow.

June 2nd, 2008
4.0 Releases in less than a week. We have seen quite bit of the final product and are still discussing issues on how to deal with 4.0 and if we'll adopt it in the future. When the GSL is announced on Friday, we'll have a better understanding. Remember the question and poll where you can still voice your opinion. Our final judgement will be announced on the June 9th podcast. Go here if anyone wishes to post questions, which we will address.

May 20th, 2008
The LE Hardcovers have finally come in. And just like that, they are going out. Like I said, these editions are a numbered edition limited to only 21 prints and include the Nick Greenwood color print many of you have seen previews of. They are all signed. Further, I have included an additional bonus: Four additional full-size B+W prints from the same artist. They are randomized so no buyer gets the same ones. The 100$ donation price still stands for those still interested. Those that paid should check out this post to verify they are getting this package.

May 17th, 2008
An important question and poll in the forum I am hoping all will read and comment on.
D&D 4.0 or 3.5-based OGL? Which will it be?

May 10th, 2008
To those in the Prince George area, the Limited Edition Softcover of Amethyst is now for sale at Great White, located in Pine Center Mall. It retails for $45.99 cdn. To those balking at the price in comparison to our web listed price, consider this: The total cost with currency conversion and shipping from our press is the same price but you don't get a signed copy with the Limited Edition Nick Greenwood print.

May 3rd, 2008
Due to the recent announcement at WOTC, we here and Dias Ex Machina have decided to reduce the prices on the Amethyst product line. It should be noted, we are not abandoning this product line, we are encouraging support to help us plan for the future.

PDF: 14.99
Softcover: 28.97
Hardcover: 38.95

April 15th, 2008

New PODCAST. This one deals with some errata on the Amethyst RPG as well as issues about future products, the ultimate direction of the game, a rift on Rifts, and the reasons why the movie Troy is somewhat overrated.

April 11, 2008

The Preview files has been replaced.  It is now called the Amethyst - Player Preview and is basically the first 33 pages of the final book.  It is for people who want to read about the game before buying the book.

April 10th, 2008

Amethyst is for sale in hardcover and softcover in the store.

March 28th, 2008

Even more artwork in the gallery.

March 26th, 2008

More artwork in the gallery.

March 25th, 2008

Time ticks away...
New final artwork from Jaime Jones in the gallery.

March 18th, 2008

Much of the artwork across the site has been replaced with selections closer to what the final book will have.

PODCAST - Our third of four podcasts before the release of Amethyst.  This one features all the voices previously (Conan, Cam, Chris, Des, and "other" Chris).  Here, we talk primarily about the artwork of Amethyst and how it has changed over the years.  We talk about much of the art which is now being featured on the site.  Huge kudos to our artists, Nick Greenwood, Jaime Jones, Jason Engle, Desmond Ng and Katherine Dinger.

March 11th, 2008

PODCAST - As promised, here is our second podcast.  It feels much tighter than the last, with less dead air and 50% more fun.  As before, it stars Chris Brown, Chris Dias, Cameron Lauder, Desmond Ng, and Conan Veitch.  We answer submitted questions and deal with why people should purchase it.  For reasons unclear, it delved into The Matrix, fantasy porn, and Ultraman.

PREVIEW - An exclusive preview of Amethyst.  You can view FINAL artwork on the game's visual style.

March 9th, 2008

Tuesday will be another podcast. With the last one, I had some regrets. I was trying for a "fly-on-the wall" feel. This next one will be better, tighter, with music. The role of Chris Dias will be played by Mathew Perry.

Tuesday will also mark the next stage of Amethyst. We will begin posting exclusive previews of Amethyst's final form. You will be able to catch finalized artwork as well as the overall feel of the game. We are all very proud over how its coming out.

February 26th, 2008

PODCAST - The first podcast from the staff of Dias Ex Machina. This one deals with the brief history of Amethyst and a detailed look at the core classes and prestige classes. The majority of the 'cast deals with the development of some noteworthy prestige classes like Urmage, Nihilimancer, and Paladin. We'll do more if this one is received well. Enjoy. 

WARNING: Harsh language and crude content.

     Pass it around and help get this little underground game noticed.  Thanks all.
