Destruction Physics: Building Demolition Sandbox is an interesting physics-based simulation of destruction and collapse of large structures, where you can use various types of weapons to destroy them. It lets you destroy the building by blowing it up, or just by throwing stuff at it. You can destroy it in various ways: by using weapons, or by using the special attack mode.
The game is a simple sandbox, where you can do all the things you want, and they all have a realistic effect. You can use your phone or tablet to control the game. You can choose to play in either single-player or multiplayer mode. You can also play on your own, by destroying buildings in your own sandbox.
The game lets you customize the behavior of the building, by changing its parameters: you can change the strength, the material, the size, and the shape. You can also change the environment, by choosing the type of terrain (or even the type of object that is being destroyed).
