About This Game

Myriad: Radiant Frontlines is a free-to-play idle RPG that fits in a corner of your desktop.

Join Joan of Arc and recruit 30 adult heroines from history and mythology around the world. Build your team, equip them and challenge six mythic bosses. Between battles, give gifts to your favorites, grow closer to them and collect their artwork.

Keep them nearby while you work. Open up the battle when you're free.


Keep a small battle window in a corner of your desktop while you work or study. Your heroines fight automatically. Check in on the action, their expressions and their little remarks whenever you like.

When you have time, expand the battlefield to watch them take on a boss, or open your team and try a different lineup. Switch between the two window sizes while the battle continues.

Raise your favorite heroines and build your team


Each heroine has her own skills and traits. Collect heroines and fragments, develop your favorites, unlock skills and choose their order of entry.

Up to three heroines fight at once, with reserves joining in turn. You decide who goes first, who deals damage and who provides protection or healing. Assemble your team and let them fight.

Challenge mythic bosses and upgrade your gear


Fight bosses for equipment and growth materials. Find suitable weapons for your heroines, compare random affixes, enhance their gear and take on tougher stages.

Stuck on a stage? Try a different lineup, or farm gear and develop your heroines before coming back.

Fight together, give gifts and collect their artwork


Fight alongside your favorites and give them gifts they like. Raise affinity to unlock illustrations in their Affinity Albums.

Separate Private Albums feature them in different outfits and settings. Revisit any picture you've collected and gradually complete your favorites' collections.

A 25-minute focus timer with rewards


Start a 25-minute Pomodoro timer when you need to focus on work or study.

Battles pause during focus time while materials and gifts accumulate. Finish the timer, collect your rewards and return to your adventure.

Free to play, with offline play


The base game is free. Keep battling and developing your heroines without an internet connection. Progress is saved locally.

A note from the developer


Hi! I'm the developer of Myriad: Radiant Frontlines, and I'm new to game development, learning as I go.

I wanted a game I'd happily keep running on my desktop: let the heroines fight while I'm busy, then spend my free time trying team setups, farming equipment, giving gifts to my favorites and collecting nice artwork.

That's how Myriad came about.

I've used a lot of AI assistance in creating and developing this game. You could call it my experiment in "AI overdrive": try an idea, throw it out if it doesn't work, and learn along the way. AI has helped me make things I could only imagine before, then keep revising them until I'm happy with them.

There's still plenty to improve. If you find bugs, stuttering, confusing controls or a stage that feels unfair, please tell me in the Steam community. Screenshots and a description of what you were doing make it easier to track down the problem.

I'll keep fixing bugs, prioritizing issues that block play, damage saves or leave rewards missing. I'll explain the fixes in the update notes.

I'll also keep adding artwork, improving animations and skill effects, and adjusting progression. Let me know your favorite heroines, outfits or settings you'd like to see, or anything that's bothering you.

Thanks for checking out my game. I hope you have fun and find a heroine you love.

Future plans


Here's what I'll keep working on:

  • Bug fixes and smoother performance: improve startup, page changes, battles and picture viewing.
  • More collectible artwork: add outfits and settings, and touch up existing pictures.
  • Battle and progression adjustments: improve animations and skill effects, and tune stage difficulty and growth pacing.

I'd also like to add:

Asynchronous team battles


Save your defensive lineup, challenge other players' teams and see whose lineup is stronger.

Equipment trading


I plan to integrate the Steam Community Market so players can trade selected UR equipment with one another.

If that sounds like your kind of game, wishlist it and follow along for updates.

Stand beside Joan of Arc, gather heroines from across the world, and open the Radiant Frontlines.
