A physics sandbox where you build scenes, rig up characters, and watch ragdoll chaos play out. This mod build opens every locked item pack, weapon, and vehicle the moment you launch it.
What Melon Sandbox is
Melon Sandbox, also listed as Melon Playground, is a 2D physics toy from 27 Studio. You drop characters, props, weapons, and machines onto a flat stage and let the physics engine do the rest. There is no goal here, no timer, and no score. The point is simple. You set up a scene and find out what happens when you pull the trigger, drop the weight, or wire two objects together.
The open structure is what pulls people in. Younger players throw together silly contraptions and stage cartoon stunts. Veteran users go further and assemble elaborate rigs with redstone-style logic, ragdoll mechanics, and custom mods pulled from the community. It sits in the same creative-sandbox bracket as Minecraft and 2D builders like Terraria, but it drops survival and crafting to focus on pure cause-and-effect play.
The base game is free with ads and a set of locked item packs you buy through in-app purchases. The modified build on this page strips those gates out, so every pack, tool, and vehicle is ready from the start.

What this mod offers
- All mods unlocked
Every premium item pack shows up unlocked on the picker. Weapons, vehicles, animals, building blocks, and logic parts that the free build hides behind a purchase are all there.
- Full weapon and vehicle set
The full arsenal and the drivable vehicles work from launch, so you can stage stunts and battles without grinding for unlocks.
- No ad interruptions
The banner and full-screen ads that interrupt the free version are gone. Your sessions stay in the sandbox instead of stopping for an ad break.
- Community mod support
Import custom item mods and texture packs the same way the official build allows, with the unlocked picker sitting underneath as a base layer.
- Same save format
Scenes you build save in the standard project format. A layout you make here opens in the official app, and a scene from the official app opens here too.
