Latest Updates from Our Project:

The 5e Update
2 months ago – Sun, Apr 26, 2026 at 10:07:05 AM

My apologies for being radio silent. I buried my mother over a month ago and today, April 24th, is her birthday. Yeah this, plus the heart attack, and it’s already been a rough year that really took the wind out of my sails.

Regardless we heard you, the fans, were not excited about our experiment to create horror-based classes that were less impactful in combat. We switched back to classes more in line with the original Esper Gensis design. Those are polished now, along with the Jitters rules and your favorite MFP monsters and we’ll be hitting layout soon.

We will be showing previews soon.

Thanks again for your patience and support.

Be Thankful For Your Health -- The 5e Park Ranger!
7 months ago – Wed, Nov 26, 2025 at 10:21:52 AM

I’ll cut the preamble. This update was interrupted by my heart attack.

The event also revealed I’m a Type II diabetic so my life is in a rearrangement mode right now. (Very luckily, I am surrounded by caring family and friends.) So partner, I strongly advise this holiday season you cherish your loved ones. When you find out how much time you have with them, it’s sort of too late.

The 5e Park Ranger!

Reaching its final form, * we have the Park Ranger ready for 5e. The Park Ranger is as much at home inside the PBSO as much as outside of it (until those voices call them back to the Pit.) Those who read a bit further will notice a new tool proficiency and a new skill!

You have already noticed, as befits a game of satire and cosmic horror, the class levels only go to 10th level. In general, PCs in horror campaigns do not last as long as a traditional campaign; and at some point, the monsters get less scary when you have killed a parade of them. Games of horror and/or humor tend to run shorter.

Regardless, enjoy! We will have more previews coming soon!

Long overdue but the Stretch goal PDF is here!
9 months ago – Wed, Oct 08, 2025 at 08:36:29 PM

The Cypher PDF Stretch Goal!

Just last week, we sent the final Stretch Goal PDF, Excursion Codicil 3.6c, out to the inboxes for Docent, Records Keeper, Vice President, C-Suite, Entrepreneur, and Senator pledges. If you haven’t seen it yet, please check your spam folders first

With over fifty pages of Mystery Flesh Pit RPG goodness, the PDF is filled scenarios, creatures, NPCs and new rules. We also have a typo form for any issues are found. If you see something, say something (pretty please.) https://forms.gle/PVrKdArrZQVguSQV7

This is the last stretch goal for the Cypher System! We appreciate your patience and hope you have fun engaging with the chaos and carnage of the Mystery Flesh Pit.

The 5e Update:

Some unexpected roadblocks allowed us more playtest time to make some tweaks to the rules. Those hurdles, however, are now gone so the project should go to editing and layout soon.  We hope to have the game out within a couple of months. I'm making a commitment to improving our communication again. Thank you again your support. 

Setbacks and GenCon.

The 5e Mystery Flesh Pit PDF

This is still going forward but real life has slowed down our team as we wrap up the last bits of design and editing.  We appreciate your patience for those who really excited for this part of the project.

MFP Stretch Goal PDF

I’ll get the unpleasantness out of the way; we lost our editor for the MFP Stretch Goal PDF at this moment.

Due to my fault, the pdf has quite a bit overstuffed and taken longer to edit than anticipated as well. It now has over 20 monsters, several locations to use and reuse for your missions in any of the three frameworks, and a couple of new tools like Secret Agendas and Manhunt Checks.

GenCon!

Which is why I’ll be taking hard copy to edit while I am at GenCon this weekend (7/31-8/3.)  You can find me for most of GenCon at the Studio 2 alley (1929, 2029), though, with SkyDawn Studios. These are the guys who will bring Phatasy Star to the ttrpg scene next year. 

Though I do plan to drop by Monte Cook Games space a few times, they can be found at ICC 131 & 132 across from the dealer’s hall. They invented the Cypher System, so you should swing by check out all the amazing, jaw-dropping things they do.

 Again, thank you all for your support as we get closer to the finish line for the KS and look into the future.
