Dungeon Flop

Build a party. Brave a dungeon. Make the next adventure your own.
Dungeon Flop is a real-time tactical RPG and dungeon-building sandbox for solo play and online co-op. Recruit a squad, equip your characters, and take them into dangerous rooms in search of loot. Then use the included creation tools to build the classes, creatures, equipment, abilities, and dungeons you want to play.
Your squad, your approach
Choose up to four characters from your roster and build around their strengths. Combine class abilities with equipment bonuses, develop your characters as they gain levels, and prepare a party that can handle what comes next. Command your units with RTS-style orders or switch to direct control of a character.
Fight, collect loot, and bring your survivors home. Between runs, manage your roster, change equipment, and decide who joins the next expedition.
Set the terms of the adventure
Play alone or join friends in a shared dungeon. The host chooses the room pool and House Rules, including enemy and reward modifiers, timers, and optional permadeath. Explore generated layouts, play an authored dungeon, or face a different challenge in modes such as Wave Defense and Endless Rooms.
Built-in chat, emotes, and dice rolls give your group room to add its own roleplaying alongside the dungeon crawl.
Creation tools come with the game
Open the in-game editors and make content of your own:
Classes and progression: Set starting stats, equipment, growth, and ability unlocks.

Items and equipment: Create bonuses, granted abilities, and stat or level requirements for different equipment slots.

Abilities and effects: Combine supported recipe steps, choose projectile artwork, and customize reusable visual effects.

Enemies and encounters: Configure creatures, AI behavior, abilities, and loot.

Rooms and dungeons: Paint spaces, place encounters, and connect your rooms into a playable adventure.
Make a returning boomerang with its own image. Create armor that requires a certain Strength or level. Give a class a new ability at a chosen level. Build a room around the enemies and rewards you designed.
Create by hand, with AI, or both
Have an idea for a dungeon, a new mob, or a strange new power? Build it yourself in the editors, ask an external AI assistant to create the content files, or switch between the two. You can delegate the file work and focus on the ideas, then open the results in the same tools to refine and playtest them.
Mod packages use local JSON and image files. Give a file-editing assistant access to your own mod folder and the bundled examples, and it can write new rooms, dungeons, creatures, classes, items, and abilities using the game's supported systems. Validate your package, test it, and share it with your group.
AI assistance is optional and uses a separate tool of your choice. No AI service is included or required to play or create content.
Learn from examples, then share your own
The bundled Core content and optional Brassworks example package show how the pieces fit together. Install Brassworks from the package manager to explore its Workshop Tour dungeon and inspect its classes, items, abilities, and rooms. Copy examples into your own package and start changing them.
Package tools let you validate, import, and export your creations for your group to play.
An ongoing experiment
Dungeon Flop is an ongoing experiment in tactical dungeon crawling and making your own adventures. Development continues, with more creation and testing tools planned alongside improvements to the existing editors. The tools and possibilities will evolve as the game develops; future additions will be detailed in update notes as they become available.
Playing with mods: The host and all joining players need matching mod packages and versions installed. Share your package with your group before starting your adventure.
