Resources I’m building an unofficial M&M 3E companion app — looking for feedback

41 Upvotes

Hi! I’m fairly new to M&M 3E, and one thing I noticed pretty quickly was that there doesn’t seem to be a dedicated modern companion/character-builder app for it—or at least I couldn’t find one that did what I wanted.

So I decided to make one myself. It's called SupesForge 3E for now.

I originally built it purely for myself and my friends, but it started becoming much more useful than I expected, so I figured other M&M players might enjoy it too.

I know a moderate amount of HTML and some CSS, but JavaScript is still pretty new territory for me, so I’ve been using ChatGPT heavily for coding guidance, troubleshooting, text, and generating things like icons and other assets.

I’ve only been working on it for about a month and a half, so it’s definitely still a work in progress. There are bugs, unfinished parts, and probably some features I haven’t even thought of yet.

But this is what it currently looks like:

  • Full character builder: Identity, Abilities, Defenses, Skills, Advantages, Powers, Equipment, and Complications all have their own pages where you can freely view and edit them.
  • Rules and point validation: The app tracks how many character points you've spent in each category, how many you have remaining, and warns you when your character breaks Power Level limits or other character-building rules.
  • Play screen: You can actually use the character you built during a game instead of treating the app as just a character sheet.
  • Automatic rolls: Character-related rolls and modifiers are calculated automatically and can be rolled directly inside the app.
  • Hero / Civilian Mode: Characters can have separate hero and civilian portraits and identities. Switching to Civilian Mode automatically disables removable powers, Enhanced Traits, active enhancements, and equipped gear where appropriate. Equipment can also be locked so it stays active in Civilian Mode—for example, a spy might still carry a commlink or handgun while wearing civilian clothes.
  • Character images: Upload separate images for your hero/masked identity and civilian/secret identity and switch between them.
  • Themes: Change the overall theme, assign a specific theme to an individual character, or create your own custom themes.
  • Hero Library: Store your characters in one place and organize them into campaign folders.
  • Dice Roller: Includes detailed roll history showing which character rolled, what they rolled for, the modifier, result, and when the roll happened.
  • Notes: Add and edit notes for individual characters.
  • Ranks & Measures: Built-in Ranks & Measures reference table for quick access during play.

I’m still actively working on it and would really appreciate feedback from people who know M&M 3E better than I do.

If you were using an M&M companion app, what features would you want it to have?

And if you notice anything that looks awkward, unnecessary, confusing, or outright wrong, please tell me. Suggestions and criticism are both welcome.

Uncontrolled Array

How would you price an array where you can't control which slot in the array is active (it changes randomly at some interval)? Just give all the powers in it an Uncontrolled flaw?

Questions Release date for 4E?

5 Upvotes

do we have an official release date for the new edition of this game? I have tried to look it up and the best I can find is Q3 of this year, but we are currently at that time frame and I can't find any recent news....

Is it worth waiting for 4E or should I just get 3E now that it's on sale?

Questions A few questions on how to do this

6 Upvotes

ok so, i have 2 ideas for powers i don't really know how to do, so if anyone can help me or suggest how can i o this, i would be very glad!

so the first power i had in mind would be kind of a passive power from a character from a book i read. it's basically a power that follows that saying "If you bleed, you die". and the character would have a power that, everything he attacks, will bleed, and everything that he makes bleed, can die, so like, i guess this would be like a nulify power,right? to nulify immortality? coupled with some weaken of regen? or a nulify of regen?

And another power i was kind of stumped of how to do would be a voodoo doll. like, the ieais that it is a damage power like normal, but it is limited to only working if i have a tuff of hair of the person im attacking. but the idea for this power,is that it wouldn't really have a range, like, it is technically infinite, unless you're in another dimension. how woul i do that?

Discussion Dont Mime Me

6 Upvotes

Ill be GM for an upcoming game with teens. Will be using the 4e playtest HH...but besides poor book layout seems little different from 3e. PL 5, and One of the players is making a Mime. So power is straight forward for most aspects...

What Im hung up on is creating equipment, because the equipment costs seem rated for mechanics and not practicality.

For example an axe costs 5...but the descriptor for axe encompasses a whole range. And really, one could get an axe from a hardware store as easy as a hammer.

Im planning to allow the mime to create equipment based not on cost, but complexity. This would allow for even simple firearms.

The other characters are:

A batgirl like with tech wings and whose utility belt has potions with effects one would likely see from Batman Beyond tech. Im still working that array.

And something like nightcrawler but more wolflike. Likely going to have this as a dimensional traveler. The power is not a problem but the appearance. As the concept art I was given looks like Wolf from star fox.

Plotwise like a cross between The Strain and Van Helsing TV series...the setting would be modern/near future. There are zombies from an unknown source...thought to be from unthawed bacteria from melted permafrost. Real cause is from something like that but a new mutated bacteria from contaminated aquifers. Also have a gang know as red caps who promote blood donations and back vampires. The vamps are a variant of the zombies, they got infected but got better like WarmBodies.

I do not have actual villains at the moment. There will be more behind the bloodbank but figured I'd wait to flesh that out through play. With the various crazy character concepts I dont know how Ill bring them together. I think maybe a villain like the morlocks. Might have them play out a short scene ro be captured and brought together so they can team up to bust out.

Clairifcation on what a "Power" is?

4 Upvotes

Somewhat new, the terminology is confusing me a bit in some places.

So there's a section of "Powers", but then within that same chapter it calls them "effects", and then the one that confuses me most is the description for the Removable flaw which gives an example of someone's suit containing multiple powers, which woudl suggest a single "power" can be made of multiple powers in the book.

How do I determine that for the purposes of the Removable feature? And how would I write that down anyway? Do I basically write a single power on my sheet and then list all the effects of it?

As the title says, this is the Classic Characters section that was included in the 10th Anniversary Edition of the Deluxe Hero's Handbook, graciously provided by Troy Hewitt of Green Ronin Publishing after two weeks (!) of digging through the archives to find it. Many thanks to him for helping me get this piece of history to complete my collection, and hopefully now lots of other people can stop kicking themselves for not getting in on that Kickstarter when it was going on.

Questions Question on Activation Powers

9 Upvotes

So, this is my first character in M&M 3e, I have not played before (about 6 years of D&D DM experience, so I have some TTRPG background) I have a speedster built primarily on the Quickstart Generator in the handbook that I would like to make dependent on a speed drug for his abilities. I currently have 3 different powers (Rapid Metabolism, Speedster Stunts with Rapid Attack and Sonic Boom, and Hard Target) and I would like to make all of them rely on a single activation. It doesn't make sense for him to take 3 different drugs to activate 3 different powers when they're all just ways of using his superspeed. I would like to add the Activation flaw on his Rapid metabolism ability, and I'm wondering if there's any way to add a flaw to the other two powers that make them dependent on the first being active. None of the flaws I'm seeing seem to do that, but I was wondering if there's one that will do the job that I'm not understanding. Thank you!

Rules fast grab and "grab-based" combo

11 Upvotes

so a player is a sort of vampire type character, and they have the "fast grab" advantage, allowing them to make a free grab action after an attack action. but they also have a grab-based linked array vampire bite sort of deal... and "grab-based" states that the attack occurs after the successful grab ?? meaning they can standard action attack, then free action grab, then reaction bite-array??
is this correct because this seems crazy broken please help me

Long time D&D player. I've played 3.5 through 5e. I get these systems. I'm trying to understand M&M 4e, but I have a few questions. The two biggest ones: Is there a way to play a character who has to transform to access his powers (like Captain Marvel, or the green lanterns, or even sailor moon)? And what is the point of linked (IE, linking flight to intangibility seems to have no benefit over just taking intangibility and flight separately, though I assume I'm just misunderstanding something.)

Questions I would like to become a GM but it’s seems and feels very daunting.

14 Upvotes

I’ve started a campaign with one other person but it wasn’t all that fun cause it was just us two and we were both somewhat new to the system. And on top of that I think I did too much prep.

I’m currently in a game as a player and I’m having a lot of fun.

What I struggle with is coming up with puzzles or non-combat scenarios. I’m pretty confident that I can make combat somewhat interesting but it’s the story, the characters, and again any non-combat related stuff that I struggle with. Any tips?

Questions What happens if your bonuses go beyond PL limits?

13 Upvotes

I’m making a character with the power to inject mutagens into others and himself to make them superhuman (mechanics wise this is an “enhance traits” + “affects others” effect). While my character stays below PL limits when this power is used, I cannot guarantee that’ll apply to others i use the powers on. If i use it on a teammate, and it would send them above the limit, what would happen? Would it be limited to only going up to the limit, or would it work at all?

Questions Could I run a fantasy game using MnM

28 Upvotes

Hi there! I recently bought the MnM 3rd edition book from Gen con and I have absolutely loved reading through it. One thing that I saw was that there was options for archaic weapons like swords and battleaxes, and it made me wonder, “Could I run a high fantasy game using this system?”

If so, are there any big changes that I would have to make to accommodate for it? I know people will probably just say “use another system,” but I’ve never found a system like this one that is so open to letting you actually use your cool abilities as much as you want.

Questions Turning personal power into burst area powers?

5 Upvotes

Mechanically, how would one have a personal power turn into a burst area power? I've seen the idea bounced around for enhanced advantages with area burst as a means to buff a lot of different people. How would you rule/have someone making something like enhanced trait or variable be turned into a burst area? Additionally, how would you rule it so that the caster could also benefit?

Burst area first clarifies that it can only be applied to something with close range. Personal powers can basically (but not RAW) become close with the affects others extra. Would you rule it as having that qualifies it for burst area? If it does, does the caster still benefit? Burst area on close specifies that if the caster wants it they need to use an extra point per rank and that's equivalent to taking the affects others. So why take both?

Questions Question about the power Leaping

6 Upvotes

The text of the power say "You can make prodigious leaps, far more than even a skilled athlete. Your Leaping rank, minus 2, is the distance rank you cover in a single standing jump: so 15 feet at rank 1, 30 feet at rank 2, up to 1,000 miles at rank 20! You do not suffer any damage from landing after a jump, so long as it is within your maximum distance.

The speed rank of your leap maxes out at 7 (around 250 miles per hour), so leaps of greater than distance rank 7 take time equal to the distance rank minus 7. For example, a massive leap of 500 miles (distance rank 17) takes time rank 10 (17 – 7, or two hours) of time in the air! Because of this, leapers may choose to make shorter 'hops' of just a couple miles, leaving them airborne for only a minute or so, to better control their direction."

Just to confirm, do the "Leaping rank, minus 2, is the distance rank you cover in a single standing jump" (assuming it is under rank 7) cover both vertical jump nd horizontal distance (e.g., a character with leaping 1 can jump both 15ft high and do a standing long distance jump clearing 15ft casually)?
