Isometric Dungeon & Caves

A pixel art isometric dungeon, cave and mine: 337 pieces on the exact 32x16 diamond grid of Gridwright Isometric Tiles: rock, dirt, moss, crystal and volcanic ground, ore in the ground and in the walls (coal, copper, iron, silver, gold, gems), mine rails that join by themselves and mine carts, cave water, acid and magma with a waterfall and a lavafall, dungeon rooms with cut-away walls, prison cells, doors and a portcullis, chests that open and a mimic that bites, traps, glowing crystals and mushrooms, and three entrances for the overworld. Every standing piece has its own shadow sprite. For dungeon crawlers, roguelikes, tactics games, mining and colony sims.

Build scenes with this pack: every piece of it is in the Gridwright Isometric Builder, an isometric map maker that runs in your browser, with all seven Gridwright isometric packs inside and Godot, Tiled and PNG export.

Licence in one line: use it in your commercial games; do not resell the files. No credit required.

What you get

• Ground (30 blocks, 18 floors, 12 ramps and stairs): cave rock, cave dirt, dungeon stone, mossy cave, crystal rock and volcanic rock (lava glowing in the cracks); 3 blocks, a half block and 3 floors each; 6 ore blocks; ramps and dungeon stairs in 4 directions.
• Liquids (40 frames): animated cave water, bubbling acid and magma, each as a block and a floor, and a waterfall and a lavafall for the left or right face of a cliff; 4 frames each.
• Mine rails (15): straights, curves, junctions, a crossing and track ends, picked by neighbour mask (the JSON and README say how), so any track joins.
• Walls (58): natural cave rock with a rough top, dressed dungeon stone and timbered mine walls; full and cut-away pieces, doorways, corners and end posts; dungeon barred windows and prison-cell bars; cave walls with ore veins in 6 ores.
• Doors (24 frames) and wall decor (28): a wooden door, a barred cell door and a portcullis that rises, 4 frames each; hook lanterns (unlit and lit), wall levers that move, shackles, a chained skeleton, a crystal lamp, hanging roots and a tool rack.
• The mine (27): mine carts (empty, coal, gold, gems) along both axes, rail bumpers, timber supports, dynamite and ore crates, a powder barrel, a pick in a rock, ore piles, a lamp post (unlit and lit) and a winch over a shaft.
• The dungeon (57 with the frames): wooden, iron and gold chests and a mimic, facing both ways, opening in 4 frames; gold and gem treasure; a spike trap and a fire trap (4 frames), pressure plates, a trapdoor shut and open, a pedestal with a glowing orb, weapon racks, straw beds, a bucket and a hanging cage.
• Cave nature (22): stalagmites, a rock column, crystal clusters in 4 colours, a giant glowing mushroom and mushroom clusters, boulders, rubble, roots, a puddle and a moss patch.
• Entrances (6): a cave mouth, a mine headframe over its shaft and a dungeon gate with stairs going down, 2x2 cells, opening left or right (drawn both ways, not mirrored), to put on an overworld map.
• 49 shadow sprites: nothing is baked into the art; each standing piece has its own shadow with the same anchor.

Made to drop in

• The same grid as our other isometric packs: 32x16 diamond, 16 px blocks, every file a multiple of 16 px. It mixes with Isometric Tiles, Isometric Characters and Isometric Monsters (sold separately).
• One JSON for everything (isometric.json): footprint, anchor, height, facing, frames and rail joins, plus the placement formula and the draw order in the README.
• Dark-ready: lanterns, fire, lava, acid, crystals and glowing fungi use their own colours, so a simple darkening shader keeps them bright, as in the screenshots.
• Clear names: rail_07.png, minecart_gold_nwse.png, chest_iron_se_f3.png, wall_cave_nw_ore_gold.png, portcullis_ne_f2.png.
• Single PNGs and sheets at 1x, 2x and 3x, and the palette (.hex, .gpl).
• The maps in the screenshots were put together from these same sprites.

Try before you buy

The free sample has 52 sprites: cave-rock and dungeon-stone blocks and floors, a gold ore block, all 15 rail pieces, cave water, a mine cart full of gold, a stalagmite, violet crystals, glowing mushrooms, six cave-wall pieces and a gold ore wall, a chest that opens and a hook lantern, with their shadows.

This pack is also in the Gridwright Megabundle: every Gridwright pack and tool for $20.

What it does not include

No characters or monsters (see Isometric Characters and Isometric Monsters), no rail ramps or rail switches that move, no corner ramps, no RPG Maker sheets and no engine project files (the README gives the placement formula and the draw order). The dark look in the screenshots is a darkening shader, not separate night sprites. The art is drawn at 1x; the 2x and 3x files are scaled copies.

Use and modify in personal and commercial projects. Shipping the tiles inside your game is fine. No resale or redistribution of the assets, modified or not. Credit is appreciated, not required. Not for AI training or NFTs.

How it was made

Every piece is drawn by code: a small ray caster draws each block, wall, cart, chest and crystal from simple solids on the exact 2:1 grid, lights it from the left and bands it onto 6-tone colour ramps. The code was written with AI-assisted tools. No image generator was used, and no third-party art is included.
