So, back in the day, d20 Spectaculars was supposed to get released, and it never ended up doing so, to my disappointment.

Dismissing Mutants & Masterminds for d20 Supers type stuff, is there any such beast for d20 Modern that I may have overlooked?

Here a few options:

• Silver Age Sentinels: d20 Edition. I don't know much about the D20 version. https://www.drivethrurpg.com/product/383/Silver-Age-Sentinels-d20-Edition
  
• Deeds Not Words, a D20 supers game written by Scott Lynch, who would later write the Locke Lamorra novels. I don't know if it is still available.
  
• The Phoenix Project, a free RPG which updates DNW. I actually like it better. http://phoenixprojectrpg.com
  
• The Anime D20 System, which is the SRD for Big Eyes Small Mouth D20. Not exactly supers, but close. http://www.opengamingfoundation.org/animesrd.html
  

Edit: Read your post too fast. You wanted D20 Modern (not D20).That limits it to Phoenix Project:

Quote from: Phoenix ProjectThis is The Phoenix Project RPG, a completely free, superhero expansion pack for d20 Modern. These rules layer on top of Modern with relatively few changes. If you know how to play Modern or D&D 3.X, then you can play this game with relative ease.

Nope, Mutants and Masterminds ate that boat.

Quote from: Christopher Brady;1071429Nope, Mutants and Masterminds ate that boat.

Not only ate that boat, but at least in this area, ate all the other Superhero boats too (there used to be a pretty active Champions group in the area, but they went Mutants & Masterminds and never looked back).

To the OP, is there a particular reason you don't want to go with Mutants and Masterminds?

I ask because 2e is pretty close to d20 Modern overall in play (six attributes, AC/defense, three saves, skill points, feats, standard and move actions, d20 conditions) and has options hit points or wounds/vitality if you don't want the toughness saves.

Alternatively for replacing Toughness Saves we've gotten good results out of giving heroes/villains 50 hit points (staggered at 20; mooks/normals only get 10hp) and having damage dealt be 1d20 + Power Level - Toughness (or other defense). Recoveries restore 10 hit points. It maps reasonably close to the average combat length produced by Toughness saves, but is less swingy.

Thanks all for the info!

It didn't get a lot of interest from the group, and we are/were hoping to find something for d20 Modern to gradually work into the current campaign we've got running right now.

BLOOD & VENGENCE: MODERN D20 SUPERHEROES.

Thanks, Lou!

These days, D20 would just not be the system I'd use for Supers. No D&D-derived system would be.

Eh, it's what we all want to play.  By and large, my group has little desire to jump to a new system.

Well, if you can kludge a functioning supers system onto D20 Modern, who are we to dissuade you?  Happy gaming!
