News about The Official Mutants & Masterminds System for Foundry VTT

New Release Coming TOMORROW!

The next release will be coming out tomorrow, Thursday September 3rd, 2026, so keep your eyes peeled for an evening release.

We've addressed a number of items and Ethaks has been working hard on getting the code together. I'm compiling a list of notes on the Bugs fixed and Features Implemented as well as a forecast for some things we are getting together.

Thanks for joining us on this journey and we appreciate all the enthusiasm and energy you bring us. It fuels and and makes us look forward to the project.

v14 Implementation May Be Delayed

Looking at the road we have to hoe and one hard talk later, we are more and more seeing the need to finalize the v13 version before moving onto the v14 version. Right now we cannot say for sure we are going to miss the September 12th, 2026 target date but it is looking more and more like it. We are not 100% if there is going to be a set date but we will endeavor to kjeep you apprised of the situation.

The next map for the Mighty Mutants & Masterminds Map Pack- THE PACIFIC MUSEUM OF ART coming this weekend!

BUT WAIT! THERE'S MORE!

Putting the finishing touches on the Journal and some last minute graphics we have for the Museum and the next in the series should be out this weekend.

I am also thinking of going back and fleshing out the Journal for the Highrise if you guys appreciate the new way I did the Journal for the Museum!

It depends a lot on your feedback, so let me know if you like what ya see.

I would also like to say how much I appreciate Ana of A Day At maps for her diligent work and freindship. She ius a marvel and a wonder and such a great artist! Kudos to her!

That's all for now!

Once the new release is out tomorrow, please dig into the release once more and look for those bugs and corrections that need to be made and KEEP THE SUGGESTIONS COMING! We appreciate you all. 🙂

BETA IS OUT!!! AUGUST 29TH, 2026
about 1 month ago – Sat, Aug 29, 2026 at 06:18:52 PM

The official Mutants & Masterminds System for Foundry VTT Beta Is Here!

Hello, everyone!
Thank you for helping us beta test the official Mutants & Masterminds system for Foundry Virtual Tabletop. Your time, feedback, and willingness to put the system through its paces will help us create something better for the entire community.

Note: You must have pledged to the AEGIS Agent pledge level in order to be part of the Beta Test.

Please remember that this is an unfinished beta—not the final product. Features may be incomplete, interfaces may change, and portions of the system’s underlying architecture may be rebuilt before release. Beta testing means actively trying the software, identifying problems, and reporting what you discover.

Please Join Us on Discord
If you have not already joined the Immersive Realms Discord server, we strongly encourage you to do so. The dedicated 3E Beta Test Feedback Forum is where we are collecting and organizing:
  • Bug reports
  • Suggestions
  • Module conflicts

Please use the forum’s posted guidelines and appropriate tags when submitting feedback. Before reporting a problem, disable all optional modules and attempt to reproduce it again.
  • If the problem still occurs with every optional module disabled, report it as a Bug.
  • If it only occurs while another module is enabled, report it as a Module Conflict and include that module’s name and version.
  • If you have an idea for improving the system’s interface, layout, workflow, or functionality, submit it as a Suggestion.
Search the forum and review the pinned list of known issues before creating a new report. Keeping each post focused on a single issue will help us track, reproduce, and resolve problems more efficiently.

Accessing Your Beta Manifest URL
You should have received an email from BackerKit containing the Manifest URL for the Mutants & Masterminds 3E Beta.

If you do not see the email, check your spam or junk folder. You should also be able to retrieve the Manifest URL by logging into your BackerKit account and opening your Digital Downloads.

Your Manifest URL provides access to the beta package. Please keep it private and do not post or share it publicly.

Before Installing
The beta currently supports Foundry VTT Version 13. Foundry VTT Version 14 is still under development and is not currently supported.
Make sure Version 13 is active before installing or using the beta.
Installing on a Self-Hosted Foundry Server
  1. Launch Foundry VTT and open the Setup screen.
  2. Confirm that you are running Foundry VTT Version 13. Version 14 is still under development and is not currently supported.
  3. Select the Game Systems tab.
  4. Click Install System.
  5. Copy the Mutants & Masterminds 3E Beta Manifest URL provided through BackerKit.
  6. Paste it into the Manifest URL field at the bottom of the installation window.
  7. Click Install and allow Foundry to download and install the system.
  8. After installation, create a new world and select the Mutants & Masterminds system from the Game System menu.

We recommend creating a dedicated test world rather than installing the beta into a world containing characters or campaign material you wish to preserve.

Installing Through The Forge
  1. Make sure Foundry VTT Version 13 is active for your Forge game. Version 14 is still under development and is not currently supported.
  2. Open The Forge and go to the Bazaar tab.
  3. Copy the Manifest URL for the Mutants & Masterminds 3E Beta from your BackerKit email or Digital Downloads.
  4. Click Install from Manifest in the upper-left corner of the Bazaar.
  5. Paste the link into the field labeled Enter the Manifest URL of the package to install.
  6. Make sure the Install from the Bazaar if the package is found toggle is turned off.
  7. Click Start to begin the installation.
  8. Once installation is complete, create or configure a Version 13 world using the Mutants & Masterminds system.

Do Not Create Permanent Characters Yet
We strongly recommend that you do not create characters you intend to keep or use in a future campaign nor start a game in a system currently in beta.
The system’s architecture may change during development. Fundamental character data, powers, items, or internal structures could be altered, requiring beta characters to be reworked or rebuilt. Test characters are encouraged, but leave your treasured heroes safely in their secret headquarters until the system is ready for release.

What We Need You to Test
Please begin with the system’s most common functions before exploring unusual combinations and edge cases:
  • Create character archetypes and variations.
  • Recreate a favorite character as a test.
  • Build powers by combining effects and modifiers.
  • Test power packages, arrays, variables, and other power containers.
  • Use the Hero Point Manager.
  • Use the Extra Effort Manager.
  • Perform actions outside combat.
  • Test action use and tracking through the Combat tab.
  • Make Damage and Affliction attacks.
  • Test area-effect Damage and Affliction attacks.
  • Drag and drop Minions and Sidekicks.
Reports will be prioritized according to their impact on normal system operation and the complexity of resolving them. Issues affecting common activities and many users will generally be addressed before rare edge cases.

Suggestions are both welcome and encouraged. We all share the same goal: making the Official Mutants & Masterminds System for Foundry VTT as useful, reliable, and enjoyable as possible.

Thank you again for joining us. Now let’s break a few things—so they work properly when the system is released!

Please reach out to me via email at [email protected] if you would like to report issues but do not wish to join the Discord server.

We are still setting up roles, permissions, and a few other features, so you may occasionally find a channel briefly behaving oddly or more limited access than you first suspected but we are getting that updated as we can when not working on the module.

Even so, this is a great time to join, introduce yourself, and help shape the community as it grows.

We look forward to seeing you there!

The Beat The Hump Promo has it's first downloads FINALLY!!!
about 1 month ago – Wed, Aug 19, 2026 at 12:34:21 PM

We Finally Figured It Out!!

I hope you feel the delay was worth it and thank you so much for your patience while we learned the intricate ins and outs of the Backerkit system!

For those who qualify for the Beat the Hump Incentive, you should have received your first of several downloads for the Mighty Mutants & Masterminds Map Pack #1.


There is a download for the V13 version (using Ripoper93's Levels system) and the v14 version (using the new native Levels system) of the Hero Highrise HQ available to you via email from Backerkit. Make sure to check your email.

Also ensure to review the included Journal in the Compendium for all the ins and outs of the package complete with a level by level walk-through of the location.

I have to warn you, this file is BIG so it will take extra time to download and use. Unless you know you are going to be using multiple levels in a combat, it is suggested that you use the individual level maps provided.

We should have the remaining maps going out every two weeks until completed!

The next map pack out will be the Museum! 

Thank you again for your patronage and patience. I hope you feel it was worth it.

Update - August 15th!
about 2 months ago – Sat, Aug 15, 2026 at 09:06:41 PM

Update - August 15th!

The delays that occurred due to the dynamic new system upgrades we’ve implemented to create a more robust and agile system module are ongoing currently and required many of the Modifiers (Extras & Flaws) to be refactored. I have typed in not only all of the Modifiers once more but also the Power Specific ones to boot. 

Again, I want to thank you for your patience. Both Ethaks and I are persistant devils. We are eliminating many small bugs to get them before it gets into your hands. We have a small team who will be doing some testing a little later this week, as a matter of fact as part of the final Alpha RE-Test we are doing after the new changes have been put into place.

We are closer and we have the Discord channel we will be sending out later once we have the Beta in your hands but until there is a Beta to test, the Discord channel will remain vacant for the time being. 

Here’s where we are at the moment…

TLDR Summary
  • BackerKit Pledge Manager - Completed and Survey Sent
  • Immersive realms Discord channel -  Created and awaiting Beta roll-out.
  • Reassessed Target Date for v13 Beta - August 29th  
  • Reassessed Target Date for v14 Beta - September 12th
  • Early Access Target Date - October 10th

Delays in coding a new system module are unavoidably expected, but never a happy event. We're making it better. We want you to be able to play with it and feel like it was worth the wait when you do.

We want you to be there through the ups and downs. We remain 100% committed to keeping you informed about our progress as we work toward delivering a stable, polished, and rewarding experience with the new Official Mutants & Masterminds System for Foundry VTT. 

If you have any questions or concerns, please share them in the comments.

The revised schedule is below, complete with more technical information and detailed account of our progress. 

Phase One: Post-Campaign Setup

Current Focus

We are still working through the immediate post-campaign steps, including:

  • Setting up and learning the BackerKit pledge manager - Completed August 10th!
  • Preparing the official Immersive realms Discord channel -  Completed, awaiting Beta Production
  • Continuing development on the Beta version - See below!

Phase Two: Beta Development & Core System Work

The OFFICIAL Mutants & Masterminds System Module is forging ahead, more slowly with some new issues being rectified. What we currently have is certainly usable for the most basic uses, I am not sure what we have is something I feel confident about putting out as a finished and polished Beta at the moment without more work to tighten up some flaws and issues just found just this week when exploring some options. 

The late change we made to integrate a more upwardly updatable and upgradable module has done a number things:

  • Made the changes we need for v14 requires retooling for the system which will take a few more weeks. v13 is nearing completion now with some final work being done specifically on Modifiers and Automation.
  • Requires retooling some features (notably the Modifiers (Extras and Flaws)) which Ethaks and I are working on as we speak.
  • Caused some delays in implementation that have now been resolved but that added to the overall delay to this point.

Because of these issues, here is the revised schedule.

Reassessed Target Date for v13 Beta - August 29th  
Reassessed Target Date for v14 Beta - September 12th


Beta Progress
  • Actions system, Outcome system, & Roll configuration system integration  - 100% Chat Message Dependency & Management with Actions system - 100% Completed 
  • Initiative/Enter Combat Box Fix - 100%  Completed
  • Modifiers (Extras and Flaws) Reconfiguration for New Outcome and Predicate system  - 90% (Completed but in testing)
  • Review and Integrate:
    • Measurement Calculator - 0%
    • Vehicle Character Sheets - 0%
    • HQ Character Sheets  - 0%
  • V14 Refit
    • Adjustment for  v14 Data Fields and Models - 0%
    • Adjustments for  v14 Active Effects Handling - 0%
    • Adjustments for v14 Styling Changes - 0%
  • Herolab Importer - 20% (Preliminary system mapping of .POR files done but they have t0o "handshake" with our system so until we've tested everything, this may be on hold until after beta)

To reiterate, the goal is to make sure the core module is stable, usable, and genuinely helpful at the table before additional content is layered on top.

Phase Three:  Backer Access, Testing, and Feedback

After the beta reaches the appropriate stage, we will begin preparing access for backers according to pledge level and project readiness.

This stage will involve:

  • Getting the Beta into backer hands
  • Collecting bug reports
  • Reviewing usability feedback
  • Making improvements based on testing
  • Preparing updates and fixes
  • Continuing toward the final release version

We want this to be useful, stable, and fun to use. Feedback will be an important part of that process.

Beta Testing v13  (Dates from August 29th to September 12th)
Beta Testing v14  (Dates from September 12th to September 26th)

Phase Four: Final Polish and Delivery

The final phase will focus on polish, cleanup, documentation, and delivery.

This includes:

  • Final bug fixes
  • Final feature review
  • Documentation and setup guidance
  • Preparing final release materials

We will continue sharing updates as production moves forward so you know what is being worked on and where things stand.

Early Access Target Date - September 26th

Phase Five: Add-Ons and Stretch Goal Content

Once the core beta work is moving smoothly, we will continue developing the promised add-ons and stretch goal content.

This includes work connected to:

  • Advanced Attack / Power Automation:   Modifiers such as Linked, Multi-Attack, and Skill-Based are automated. Additional automation of the powers Weaken, Nullify, or powers with Partial Modifiers gain automation as well to reduce manual oversight and keep the action moving. - 20% (Some headway is being made just as an ancillary feature of the new systems implemented)
  • Interaction Skill Automation: Interaction skills such as Startle, Taunt, and Demoralize will all able to affect foes and place the appropriate conditions on them. - 100% Completed already and will be available in Beta.
  • A Simplified Character Sheet: An easy-to-read character sheet that still retains both Mouse-Over Tooltip and Click-and-Roll features when you want a simplified view of your character. - 5%
  • Foundry-Ready Maps from Emerald City: The Cannery entryway and Atlas Mall parking lot from the Emerald City Sourcebook get Foundry-ready scenes both by awesome mapmaker Kidneyboy. - 100% Completed, ready for addition to the Emerald City 
  • Additional Content (i.e. Sourcebooks)  promised through the campaign - 10%

As specific details become available, we will get them out to you.

We want to thank you for your patience. We want to make this the best it can be for you, players and Gamemasters of Mutants & Masterminds and the faithful followers of Green Ronin Publishing.

Thank you again, and...

Keep fighting the good fight.
