If you're making a map for R2DA, you can use this page as a reference to help you out.
Standards have been raised, and even if you follow all of the rules, that doesn't mean that it'll be added.
- Preferably, no free models of all should be in the map.
- If you must, it has to be of a small quantity that matches the build quality already set in the map.
- This is only if the map looked okay with free models to begin with.
- Map design that supports R2DA's gameplay and Gamemodes.
- Consider choke points, zombie spawning.
- This depends on map size.
- Don't make the map too open, or way too small.
- A moderate amount of detail.
- No effortless block-like builds. Put some time into it.
- Maps don't necessarily have to be dark and gritty, but you shouldn't make it look saturated enough to the point that it came from a cartoon.
- Meshes are fine within the map if they are replacing unions. If you are using unions, limit the number used within the map.
- You can put water into the map as long as it's terrain-water and not just some big blue block.
For your map to be accepted by PlaceRebuilder, tweet him at him or make a thread here on the Wikia.
It isn't guaranteed if your map is going to be added unless he messages you outright confirming it.
