Frigga - Procedural Dungeon, Level & Map Generator

Work the way you prefer: generate procedurally, hand-author with the built-in Level Editor, or combine both. Frigga ships with layout generators for different terrain types, an extensible API for custom generators, and deterministic seeding so every seed reproduces exactly - across platforms and Unity versions.

🗺️ Generate the map you need

From natural islands and cave networks to organic dungeons and open overworlds - Frigga covers a wide range of 2D maps and terrain types:

• Procedural terrain - islands, forests, biomes, overworlds
• Caves and dungeons - winding corridors, cave networks, organic dungeon maps
• Your own generator - extend Frigga with custom generators via a clean API

Each generator comes with sensible defaults and deep configurability. Need something specific? The Level Editor lets you paint levels by hand - or mix hand-authored Structures into procedurally generated maps. See Demos →

🎨 Decorate your map with the Theme Engine

Torches appear on walls. Trees grow only on grass. Moss creeps across old stone. The Theme Engine handles all of this through placement rules you set up in a dedicated editor - similar in spirit to Unity's Rule Tiles, but expanded to work across multiple layers.

🏰 Mix handmade design with procedural power

Need guaranteed features like a spawn area, boss arena, or treasure room? Structures are hand-authored chunks placed into generated levels - with control over where they appear, how often, and how far apart they sit.

⚙️ Designed for modern Unity workflows

• Fully supports Unity 6
• Runs in the editor or at runtime
• Works with both Tilemaps and GameObjects
• Easy Collider and NavMesh integration
• Deterministic seeding - same seed, same level on any platform or version
• Extensible with custom generators, post-processing, and generation hooks
• Great for 2D levels and some 3D tile-based setups
• Comprehensive documentation + full source code

Building strict room+corridor dungeons (Enter the Gungeon-style)? Our other asset, Edgar Pro, is built specifically for that. Frigga is built for organic, natural-feeling levels and maps - whether procedurally generated, hand-authored, or a mix of both.
