Build a 3D level out of blocks: stairs, doors, monsters, traps and treasure. Press Play and walk it in first person. Free, in your browser, works on phones.
How to use
- Pick a block in the palette and tap or click a face to build on it. Drag to keep building; Page Up and Page Down (or the arrows by Layer) change the layer you build on.
- Add a Start and an Exit, then stairs, doors and levers, keys, monsters, chests and traps such as spikes, fire vents, arrow traps, trap doors and springs.
- Use Plan view to draw a layer from above like a map, and Check level to see whether the level can be finished and what is in the way.
- Press Play. On a computer, look with the mouse and move with W A S D, Space to jump. On a phone, the stick on the left walks, dragging the view looks round, and the buttons jump, fire and use.
- Copy link shares your level, and Download file saves it to open again later.
Frequently asked questions
Do I need to install anything?
No. The maker and the game run in your browser on a computer, a tablet or a phone. Your level is saved on your device as you build.
Does it work on a phone?
Yes. Full screen fills the phone for building and playing: one finger builds, two fingers turn and zoom the view, and Play has an on-screen stick and buttons.
Where do the monsters come from?
They are made by Pixel Monster Maker, our free pixel creature builder. Each one is saved with your level, so a shared link shows the same monsters.
How is it different from Retro FPS Maker?
Retro FPS Maker draws a flat maze on a grid. 3D Adventure Maker builds with cubes in layers, so levels have height: stairs, ledges, jumps, crawl spaces and secret passages behind cracked blocks.
