Collapsion: Demolition Sandbox

Collapsion Sandbox is a voxel destruction sandbox where buildings behave like the real thing. Every structure holds itself up. Cut a load-bearing support, and the whole thing collapses under its own weight!

Ever notice how in other destruction games a building stands on a single thread of blocks and refuses to fall? Here it works differently. This demolition sandbox runs on real structural integrity with actual load calculation. Nothing floats in mid-air or balances on a fragile support. It comes down the way it really would.

WHAT'S INSIDE

💥 Real collapse physics. Nothing is scripted: buildings fold, topple and crumble under their own weight. Knock out a support, the weight does the rest!
🏗️ Fully destructible voxel sandbox: every voxel can be broken, all the way down to the last one
🌍 Community levels: build your own destructible levels, publish them, and download levels made by other players
📦 Spawn menu: pick any object and drop it straight into the scene
🚗 Cars and planes: drive through walls, crash a plane into anything you like
🧍 Ragdoll physics: throw them around, bury them in the rubble
🔫 Physics gun: grab anything, lift it, launch it
🔥 Tools of destruction: pistol, bomb, rocket launcher, flamethrower, and a spray can for those who'd rather paint the ruins. Blow up buildings however you like
💾 Save your scenes: build it once, come back and wreck it again
🐢 Slow motion: watch every explosion and collapse frame by frame
📱 Optimized for phones: massive destruction without turning into a slideshow

IN DEVELOPMENT

Multiplayer, more vehicles and new destruction tools are on the way.

Built by one person who just wanted buildings to fall properly. Play it, break it, tell me what's missing. Reviews genuinely decide what gets built next.

Build it, publish it. Then knock out a support and watch it all come down!
